With a dashboard, different graphs can be displayed on the same screen. Different graphs, such as line graphs and digit graphs can be used to display resource data, so that you can view monitoring data comprehensively.
+
You can add key resource metrics to a dashboard and monitor them in real time. You can also compare the same metric of different resources on one screen. In addition, by adding routine O&M metrics to a dashboard, you can perform routine checks without re-selecting metrics when you open AOM again.
+
Before creating a dashboard, learn the types of graphs that can be added to a dashboard for accurate resource monitoring. The following graphs can be added to a dashboard:
+
Metric Data Graphs (Including Line and Digit Graphs)
Line graph: displays the metric data trend by time. Use this type of graph to monitor the metric data trend of one or more resources in a period. Titles of metric data graphs can be customized.
You can use a line graph to compare the same metric of different resources. The following figure shows the CPU usage of different hosts.
+

Viewing Alarms
+
Alarms are the information reported when AOM or an external service such as Cloud Container Engine (CCE) is abnormal or may cause exceptions. Take measures to resolve faults. Otherwise, service exceptions may occur.
+
Viewing Alarms
Log in to the management console.
Under Application, click Application Operations Management.
In the navigation pane, choose Alarm Center > Alarms.
Alarms are displayed by time. The alarm generated at the latest time is displayed at the topmost of the alarm list.
You can also click on the right of the page to view the latest three alarms.
+
+
Set the time range or filter criteria.
Set the time range.
View the alarms generated within the time range. There are two methods to set a time range:
+
Method 1: Use the predefined time label, such as Last 1 hour, Last 6 hours, or Last 1 day. You can select a time range as required.
+
Method 2: Specify the start time and end time to customize a time range. You can specify 30 days at most.
+
Set filter criteria.
Enter an alarm status, name, or source, and click Search.
+
You can click Reset to reset filter criteria.
You can enter multiple alarm sources and separate them by using commas (,) to filter alarms.
Alarm names and sources are case-sensitive.
+
+
+
View the search result.
In the bar graph, view the statistics of alarms that meet the filter criterion within the time range specified in 4.

+
In the alarm list, view the information about alarms that meet the filter criterion within the time range specified in 4.
Click View Details in the Operation column to view alarm details.
+
Figure 2 Alarm list
+
+
Clear alarms.
In the Operation column of the target alarm, click Clear.
+
In addition, AOM supports automatic clearance of alarms triggered by threshold rules. For example, you create a threshold rule. That is, if the CPU usage exceeds 85%, a threshold alarm will be generated. If the CPU usage is lower than 85%, the alarm will be cleared. In this case, you do not need to manually clear the alarm. When the CPU usage returns to normal, the threshold alarm will be automatically cleared. In addition, when the threshold rule is deleted, the threshold alarm will also be automatically cleared.

Host Monitoring
+
AOM monitors the resource usage and health status of hosts, common system devices such as disks and file systems of hosts, and service processes or instances running on hosts.
+
The ICAgent reports resource information every ten minutes. The resource status changes are described as follows:
+
If the ICAgent on a host does not report resource information for three consecutive times, the system determines that the resource has been deleted. Therefore, the host status is displayed as Deleted within 30 minutes after the host is stopped or the ICAgent is uninstalled.
When the ICAgent on a host reports resource information for one time, the system determines that the resource is restored. The host status is displayed as Normal ten minutes after the host is started or the ICAgent is reinstalled.
+
+
Precautions
A maximum of five tags can be added to a host, and each tag must be unique.
The same tag can be added to different hosts.
For hosts created on the CCE or ServiceStage console, you cannot select clusters or create aliases for them.
The host status can be Normal, Abnormal, Warning, Silent, or Deleted. The running status of a host is displayed as Abnormal when the host is faulty due to network failures, and power off or shut down of the host, or when the host generates a threshold alarm. If resources are not running properly, follow the instructions in What Can I Do If Resources Are Not Running Properly?.
+
+
Procedure
Log in to the management console.
Under Application, click Application Operations Management.
In the navigation pane, choose Host Monitoring and perform the following operations as required:
Adding an alias
If a host name is too complex to identify, you can add an alias, which makes it easy to identify a host as required.
+
In the host list, choose More > Add Alias in the Operation column of a desired host.
+
Adding a tag
Tags are identifiers of hosts. You can manage hosts using tags. After a tag is added, you can quickly identify and select a host.
+
In the host list, click Add tags in the Operation column of the row that contains the target host. In the displayed dialog box, click , enter a tag, and click and OK. After a tag is added, you can enter a tag keyword in the search box in the upper right corner of the page to search for a host. The Tags column of the host list is hidden by default. You can click in the upper right corner and select or deselect Show tag.
+
+
Set filter criteria to search for the host to be monitored and monitor resource usage and health status of the host.
Figure 1 Monitoring the resource usage and health status of the desired host
+
Click the host name to enter the Host Details page. In the instance list, monitor the resource usage and health status of the instances running on the host. Click the View Monitor Graphs tab to monitor all the metrics of the host.
Creating a view template
AOM provides the default view template (Host Template) that you can modify. You can also click the plus sign (+) in to add you own template.
+
Adding a metric graph
You can click to add a line graph or to add a digit graph to the view template. You can also delete, move, and copy metric graphs in the view template according to Dashboard.
+
Adding a view template to a dashboard
On the host details page, choose More > Add To Dashboard in the upper right corner to add the view template to a dashboard for monitoring.
+
+

Searching for Logs
+
AOM enables you to quickly query logs, and use log source information and context to locate faults.
+
Log in to the management console.
Under Application, click Application Operations Management.
In the navigation pane, choose LogManagement > Log Search.
On the Log Search page, set filter criteria as prompted.
You can search for logs by service, system, or host.
For service logs, you can set filter criteria such as Cluster, Namespace, and Service. You can also click Advanced Search and set filter criteria such as Instance, Host, and File Name, and choose whether to enable Hide System Service.
For system logs, you can set filter criteria such as Cluster and Host.
For host logs, you can set filter criteria such as Cluster and IP Address.
+
Enter a keyword in the search box. Rules are as follows:
Enter a case-sensitive keyword.
Enter a keyword for exact search. A keyword refers to a word between two adjacent delimiters.
Enter a keyword containing an asterisk (*) or a question mark (?) for fuzzy search. For example, enter ER?OR, *ROR, or ER*R.
Enter a phrase for exact search. For example, enter Start to refresh or Start-to-refresh. Note that hyphens (-) are delimiters.
Enter a keyword containing AND (&&) or OR (||) for search. For example, enter query logs&&error* or query logs||error.
If no log is found, you are advised to narrow down the search scope and add an asterisk (*) before and after the keyword for fuzzy match.
+
+
+
View the search results of logs.
The search results are sorted based on the log collection time. The keywords in the search results are highlighted.
+
By default, the descending order is used. You can click in the Time column to change the order. indicates the ascending order by time (that is, the latest log is displayed at the end). indicates the descending order by time (that is, the latest log is displayed at the top).
+
Click on the left of the log list to view details such as host IP address and source.
AOM allows you to view the surrounding logs of a specified log by clicking View Context in the Operation column, facilitating fault locating. Therefore, you do not need to search for logs in raw files.
In the Display Rows drop-down list, set the number of rows that display raw context data of the log.
For example, select 200 from the Display Rows drop-down list.
+
If there are more than or equal to 100 logs printed prior to a log and more than or equal to 99 logs printed following the log, the preceding 100 logs and following 99 logs are displayed as the context.
If there are fewer than 100 logs (for example, 90) printed prior to a log and fewer than 99 logs (for example, 80) printed following the log, the preceding 90 logs and following 80 logs are displayed as the context.

To ensure that tenant hosts and services run properly, some components (for example, kube-dns) provided by the system will run on the tenant hosts. The logs of these components are also queried during tenant log query.
+
+
(Optional) Click on the right of the Log Search page, select an export format, and export the search result to a local PC.
Logs are sorted according to the order set in 5 and a maximum of 5000 logs can be exported. For example, when 6000 logs in the search result are sorted in the descending order, only the first 5000 logs can be exported.
+
Logs can be exported in CSV or TXT format. You can select a format as required. If you select the CSV format, detailed information (such as the log content, host IP address, and source) can be exported, as shown in Figure 1. Only log content will be exported when you select the TXT format (as shown in Figure 2). Each line indicates a log.

Configuring VM Log Collection Paths
+
AOM can collect and display VM logs. VM refers to an Elastic Cloud Server (ECS) running Linux. Before collecting logs, configure a log collection path according to the following procedure.
The ICAgent collects *.log, *.trace, and *.out log files only. For example, /opt/yilu/work/xig/debug_cpu.log.
Ensure that an absolute path of the log directory or file is configured and the path exists. For example, /opt/yilu/work/xig or /opt/yilu/work/xig/debug_cpu.log.
The ICAgent does not collect log files from subdirectories. For example, the ICAgent does not collect log files from the /opt/yilu/work/xig/debug subdirectory of /opt/yilu/work/xig.
A maximum of 20 log collection paths can be configured for a VM.
For ECSs in the same resource set, only the latest log collection configuration in the system will be used. AOM and LTS log collection configurations cannot take effect at the same time. For example, if you configure log collection paths in AOM for ECSs, the previous LTS collection configurations of all ECSs under the resource set become invalid.
+
+
Procedure
Log in to the management console.
Under Application, click Application Operations Management.
In the navigation pane, choose Log Management > Path Configuration.
In the VM list, click Configure in the Operation column to configure one or more log collection paths for a VM.
You can use the paths automatically identified by the ICAgent or manually configure paths.
Using the paths automatically identified by the ICAgent
The ICAgent automatically scans the log files of your VM, and displays all the log files that have file handles and are suffixed with .log, .trace, or .out on the page.
+
You can click in the Operation column to add a path automatically identified by the ICAgent to the log collection path list. To configure multiple paths, repeat this operation.
+
Figure 1 Using the paths automatically identified by the ICAgent
+
Manually configuring log collection paths
If the paths automatically identified by the ICAgent cannot meet your requirements, enter a log directory or file (for example, /opt/yilu/work/xig/debug_cpu.log) in the Log Collection Path text box, and then click to add the path to the log collection path list. To configure multiple paths, repeat this operation.
After a log collection path is configured, the ICAgent collects log files from the configured path. The collection takes about 1 minute. After log files are collected, choose Log Management > Log Files in the navigation pane and then click the Host tab to view the collected log files.
Generally, events carry important information, informing you of the changes of AOM itself or an external service such as Cloud Container Engine (CCE). Such changes do not necessarily cause exceptions. Events do not need to be handled.
+
Viewing Events
Log in to the management console.
Under Application, click Application Operations Management.
In the navigation pane, choose Alarm Center > Events.
Events are displayed by time. The latest event is displayed at the topmost of the event list.

Set the time range.
View the events generated within the time range. There are two methods to set a time range:
+
Method 1: Use the predefined time label, such as Last 1 hour, Last 6 hours, or Last 1 day. You can select a time range as required.
+
Method 2: Specify the start time and end time to customize a time range. You can specify 30 days at most.
+
Set filter criteria.
Enter an event name and source, and click Search.
+
You can click Reset to reset filter criteria.
You can enter multiple event sources and separate them by using commas (,) to filter events.
Event names and sources are case-sensitive.
+
+

+
View the search result.
Viewing statistics in a bar chart
The bar chart shows the number of logs that meet the filter criteria set in step 4 at different time points. The horizontal axis represents the time and is divided into 30 identical rectangular blocks. The time of each rectangle block is calculated by dividing the selected time range by 30. For example, if the time range is 30 minutes, the time of each rectangle block is 1 minute. If the time range is 60 minutes, the time of each rectangle block is 2 minutes. The vertical axis represents the number of logs that meet filter criteria.
+

Sort search results: Logs are sorted based on the collection time in descending order by default. You can click in the Collection Time column to change the order. When you click the black triangle icon to sort logs by time in ascending order, the latest log is displayed at the end. When you click the black triangle icon to sort logs by time in descending order, the latest log is displayed at the top.
View the context of a specified log: AOM allows you to view the previous or next logs of a specified log by clicking View Context in the Operation column, facilitating fault locating. Therefore, you do not need to search for logs in raw files.
What Is the Relationship Between the Time Range and Statistical Cycle?
+
In AOM, a maximum of 1440 data points can be returned for a single metric query. The relationship between the time range and statistical cycle is as follows:
+
Maximum time range = Statistical cycle x 1440
+
If you select a time range shorter than or equal to the maximum time range, all the statistical cycles that meet the preceding formula can be selected. For example, if you want to query metrics in the last hour, the available statistical cycles are 1 minute and 5 minutes.
+
For a dashboard, the relationship between the time range and statistical cycle is shown in the following table.
+
+
Table 1 Relationship between the time range and statistical cycle
Application Operations Management (AOM) is a one-stop, multi-dimensional O&M management platform for cloud applications. It monitors applications and related cloud resources in real time, collects and associates resource metrics, logs, and events to analyze application health status, and provides flexible alarm reporting and data visualization, helping you detect faults in a timely manner and monitor the running status of applications, resources, and services in real time.
+
Specifically, AOM comprehensively monitors and uniformly manages cloud servers, storage devices, networks, web containers, and applications hosted in Docker and Kubernetes, effectively preventing problems, facilitating fault locating, and reducing O&M costs. In addition, AOM provides unified APIs for interconnecting self-developed monitoring or reporting systems. Unlike traditional monitoring systems, AOM monitors services by applications, meeting your requirements for high efficiency and fast iteration. It provides effective IT support for your services, and protects and optimizes your IT assets, enabling you to achieve strategic goals.
AOM supports services such as Simple Message Notification (SMN), Cloud Trace Service (CTS), and Cloud Container Engine (CCE). You can use them after subscription. For example, after you subscribe to SMN, threshold rule status changes of AOM can be sent to related personnel by email or Short Message Service (SMS) message.
+
SMN
SMN can push notifications based on your requirements, and end users can receive notifications by SMS message, email, or application. You can also integrate application functions through SMN to reduce system complexity.
+
AOM uses the message transmission mechanism provided by SMN. When it is inconvenient for you to query threshold rule status changes in time through AOM, SMN can send the changes to you by email or SMS message in a timely manner. In this way, you can obtain information such as resource running status in real time and take necessary measures to avoid service loss.
+
+
CTS
CTS records operations on cloud resources in your account. You can perform security analysis, track resource changes, conduct compliance audits, and locate faults based on operation records. To store operation records for a longer time, you can subscribe to Object Storage Service (OBS) and synchronize operation records to OBS in real time.
+
With CTS, you can record operations associated with AOM for later querying, auditing, and backtracking.
+
+
CCE
CCE provides high-performance and scalable container service, enabling you to build reliable container clusters based on cloud servers. It integrates network and storage capabilities, and is compatible with Kubernetes and Docker container ecosystems. CCE enables you to create and manage diverse container workloads easily. It also provides efficient O&M capabilities, such as self-healing of container faults, collection of monitoring logs, and auto scaling.
+
You can use AOM to monitor applications deployed on CCE.
What Can I Do If Resources Are Not Running Properly?
+
Resource statuses include Normal, Warning, Abnormal, Deleted, and Silent. Warning, Abnormal, and Silent indicate improper resource running. Analyze and rectify faults according to the following instructions.
+
Warning
If a minor alarm or warning exists, the resource status is Warning.
+
Suggestion: Handle the alarm based on alarm details.
+
+
Abnormal
If a critical or major alarm exists, the resource status is Abnormal.
+
Suggestion: Handle the alarm based on alarm details.
+
+
Silent
If the ICAgent fails to collect resource metrics, the resource status is Silent. The causes include but are not limited to:
+
Cause 1: The ICAgent is abnormal.
Suggestion: In the navigation pane, choose Agent Management. On the page that is displayed, check the ICAgent status, as shown in Figure 1. If the status is not Running, the ICAgent has been uninstalled or is abnormal. For details on how to solve the problem, see Table 1.
Wait for about 1 minute to complete the ICAgent installation.
+
+
+
Installation failed
+
+
If the ICAgent fails to be installed, reinstall it.
+
+
+
Upgrading
+
+
Wait for about 1 minute to complete the ICAgent upgrade.
+
+
+
Upgrade failed
+
+
If the ICAgent fails to be upgraded, reinstall it.
+
+
+
Offline
+
+
Check for network faults and rectify such faults.
+
+
+
Faulty
+
+
Contact technical support.
+
+
+
+
+
+
Figure 1 Checking the ICAgent status
+
+
Cause 2: AOM cannot monitor the current resource.
Suggestion: Check whether your resources can be monitored by AOM. AOM can monitor hosts, Kubernetes containers, and user processes, but does not monitor system processes.
+
Cause 3: The local time of the host is not synchronized with the NTP server time.
NTP Sync Status: indicates whether the local time of the host is synchronized with the NTP server time. The value can be 0 or 1. 0 indicates the synchronized status while 1 indicates the asynchronized status.
+
+
Suggestion: Choose View Management > Metric Monitoring and check the NTP Sync Status metric of the host. If the value of NTP Sync Status is 1, the local time of the host is not synchronized with that of the NTP server. To solve the problem, perform synchronization.
+
Cause 4: The resource is deleted or stopped.
Suggestions:
+
On the ECS page, check whether the host is restarted, stopped, or deleted.
On the Cloud Container Engine (CCE) page, check whether the component is stopped or deleted.
Metrics reflect resource performance data or status. A metric consists of the namespace, dimension, name, and unit. Metrics are classified into system metrics and custom metrics.
+
System metrics: basic metrics provided by AOM, such as CPU usage and used CPU cores.
Custom metrics: self-defined metrics. Custom metrics can be reported using the following methods:
Method 1: Use the AOM API for reporting monitoring data.
Method 2: Connect to the Prometheus platform when creating container applications on Cloud Container Engine (CCE).
+
+
Metric Namespaces
Metric namespaces indicate containers for storing metrics. Metrics in different namespaces are independent of each other so that metrics of different applications will not be aggregated to the same statistics information.
+
Namespaces of system metrics cannot be changed. These namespaces must start with PAAS., as shown in Table 1.
+
Table 1 Namespaces of system metrics

+
+
+
+

+
+
+
PAAS.CONTAINER
+
+
Namespace of service, instance, process, and container metrics
+
+
+
+
+
+
+
Namespaces of custom metrics must be in the XX.XX format (excluding PAAS.XX, SYS.XX, or SRE.XX). Each namespace must be 3 to 32 characters long and start with a letter. Only digits, uppercase letters, lowercase letters, and underscores (_) are allowed. For example, aom.host_01.
+
+
Metric Dimensions
Metric dimensions indicate the categories of metrics. Each metric has certain features, and a dimension may be considered as a category of relevant features.
The dimensions listed in Network Metrics and Dimensions to Service Metrics and Dimensions are the dimensions of metrics collected and reported by the AOM backend. You can select these dimensions when calling APIs. Resources are filtered and displayed by dimensions on the AOM frontend.
+
+
Dimensions of custom metrics must be 1 to 32 characters long, which need to be customized.

For workloads deployed on Cloud Container Engine (CCE), AOM supports drill-down from services to service instances, containers, and processes. For services that directly run on VMs, AOM supports drill-down from services to service instances and processes. In this way, you can implement multi-dimensional monitoring.
Service metrics consist of instance metrics. The dimensions of service metrics are the same as those of instance metrics. For details, see Instance Metrics and Dimensions.
Services refer to containers and common processes you deploy. For example, a workload on Cloud Container Engine (CCE) is a service, and the Tomcat running on a VM is also a service.
+
The service list displays the type, CPU usage, memory usage, and alarm status of each service, helping you learn services. You can click a service name to learn more information. AOM supports drill-down from a service to a service instance, a container, and then to a process. In this way, you can implement multi-dimensional monitoring.
+
Procedure
In the navigation pane, choose Service Monitoring and perform the following operations as required:
Adding an alias
If a service name is complex and difficult to identify, add an alias for the service.
+
Choose More > Add alias in the Operation column, and specify an alias.
+
+
Adding a tag
Tags are used to identify services. You can distinguish system and non-system services using tags. By default, AOM adds the System Service tag to system services, including icagent, css-defender, nvidia-driver-installer, nvidia-gpu-device-plugin, kube-dns, org.tanukisoftware.wrapper.WrapperSimpleApp, evs-driver, obs-driver, sfs-driver, icwatchdog, and sh. You can click in the upper right corner to select or deselect Hide system services. You can also customize tags to facilitate service management.
+
In the service list, choose More > Modify Tag in the Operation column of the service. On the displayed page, click to enter a tag, and click and OK. After the tag is added, enter a tag keyword in the search box in the upper right corner of the page to search for services.
+
By default, the Tag column of the service list is hidden. You can click in the upper right corner and select or deselect Tag to show or hide them. In the Tags column, use double quotation marks ("") to separate tags. Enter the content in double quotation marks when using tags to search for services.

Creating Threshold Rules
+
To use threshold rules, customize threshold conditions first. If a metric value meets a threshold condition, AOM generates a threshold alarm. If no metric data is reported, AOM generates an insufficient data event.
+
AOM is interconnected with Simple Message Notification (SMN). After you set a notification policy on the SMN console, notifications are sent by email or Short Message Service (SMS) message if the threshold rule status (Exceeded, OK, or Insufficient) changes. In this way, you can identify and handle exceptions at the earliest time.
+
Precautions
You can create a maximum of 1000 threshold rules. To create more rules when the maximum number is reached, delete unnecessary rules.
Setting a notification policy
To send notifications by email or SMS message if the threshold rule status (Exceeded, OK, or Insufficient) changes, set a notification policy on the SMN console according to the following procedure. If you do not need to receive notifications by email or SMS message, skip the following operations. Procedure:
Select apm for Services that can publish messages to this topic. Otherwise, notifications cannot be sent.
+
Add a subscriber (email or SMS message recipient) for the topic by referring to Adding a Subscription.
+
+
+
+
Creating Threshold Rules
Log in to the management console.
Under Application, click Application Operations Management.
In the navigation pane, choose Alarm Center > Threshold Rules. Then, click Add Threshold Rule in the upper right corner.
Create a threshold rule.
Select resources: Enter a threshold rule name, select a resource type, select the resources to be monitored from the resource tree, and click Next.
You can select a maximum of 10 resources from the resource tree.
When multiple resources are selected, multiple threshold rules will be created after the creation is complete. Each resource is monitored by a threshold rule. A rule name consists of the threshold rule name you enter in the Threshold Name text box, and a sequence number ranging from 0 to 99. The earlier a resource is selected, the smaller its sequence number.
For example, enter Monitor_Host_cpuUsage in the Threshold Name text box and select the aom-1 host and then the aom-2 host from the resource tree. In this way, threshold rules Monitor_Host_cpuUsage0 and Monitor_Host_cpuUsage1 will be generated. The former monitors the aom-1 host while the latter monitors the aom-2 host.
+
+
+
Figure 1 Selecting resources
+
Customize a threshold. Specifically, select the metric to be monitored, and set parameters such as Threshold Condition, Consecutive Period (s), Alarm Severity, Statistic, and Send Notification.
Threshold Condition: Trigger condition of a threshold alarm. A threshold condition consists of two parts: determination condition (≥, ≤, >, or <) and threshold value. For example, if Threshold Condition is set to > 85 and an actual metric value exceeds 85, a threshold alarm will be generated.
Consecutive Period (s): If a metric value meets the threshold condition for a specified number of consecutive periods, a threshold alarm will be generated.
Statistic: Method used to measure metrics.
Statistical Period: Interval at which metric data is collected. The system collects a data point every minute to determine the status of the threshold rule.
Send Notification: Whether to send a notification by email or SMS message if the threshold rule status (Exceeded, OK, or Insufficient) changes.
If you need to receive notifications by email or SMS message, select Yes, set a notification policy, select the created topic, and select a trigger condition.
If you do not need to receive notifications by email or SMS message, select No.
+
Trigger Condition: Condition for sending notifications.
You can select multiple trigger conditions for a threshold rule. For example, to receive notifications if the threshold status changes to Exceeded, select Threshold crossing. To receive notifications upon any threshold status change, select all trigger conditions.
+
+
+
Figure 2 Customizing a threshold
+
+
Click Submit. As shown in the following figure, multiple threshold rules are created. Each resource is monitored by an independent rule.
If the CPU usage of a host exceeds 85%, a threshold alarm is generated on the alarm page. You can choose Alarm Center > Alarms in the navigation pane to view the alarm. If the host meets the preset notification policy, an email or SMS message will be sent to the specified recipient.

Set an interpolation mode
+
+
By default, AOM uses Null to represent breakpoints in a metric graph, as shown in Figure 1. However, a metric graph with breakpoints is not suitable for reports or presentation. To solve the problem, set the value of Interpolation Mode to 0 or Average to interpolate values. In this way, you can replace the missing metric data and avoid breakpoints.
+
The value of Interpolation Mode can be Null, 0, or Average.
+
Null: Breakpoints are represented by Null by default.
Figure 1 Graph when the value of Interpolation Mode is Null
+
0: Breakpoints are represented by 0.
Figure 2 Graph when the value of Interpolation Mode is 0
+
Average: Breakpoints are represented by the average value.
Figure 3 Graph when the value of Interpolation Mode is Average
+
NOTE:
If the value of Interpolation Mode is set to Average, breakpoints will be represented by average values. The following describes how to calculate average values.
+
A metric graph may have multiple breakpoints. When multiple breakpoints exist, values will be interpolated for these breakpoints from left to right. The following uses the first breakpoint in a graph as an example to describe the method of calculating the average value. This method can also be applied to other breakpoints.
+
If the first breakpoint is at the start of a metric graph, the value of the breakpoint is the first valid data from its next point to the right.
For example, if a metric graph has points a, b, c, d, and e, where a = Null, b = Null, c = Null, d = Null, and e = 5, the value of the first breakpoint (that is, point a) is 5.
+
If the first breakpoint is in the middle of a metric graph, there are the following two scenarios:
Scenario 1: If the values of the previous and next points of the breakpoint are valid, the value of the breakpoint is the average value of these two points.
+
For example, if a metric graph has points a, b, c, d, and e, where a = 1, b = Null, c = 3, d = Null, and e = 5, the value of the first breakpoint (that is, point b) is (a + c)/2 = (1 + 3)/2 = 2.
+
Scenario 2: If the value of the previous point of the breakpoint is valid and the value of its next point is null, the value of the breakpoint is the average value of its previous point and the first valid data from its next point to the right.
+
For example, if a metric graph has points a, b, c, d, and e, where a = 1, b = Null, c = Null, d = Null, and e = 5, the value of the first breakpoint (that is, point b) is (a + e)/2= (1 + 5)/2 = 3. Because values are interpolated for breakpoints from left to right, the value of the second breakpoint (that is, point c) is (b + e)/2 = (3 + 5)/2 = 4, the value of the third breakpoint (that is, point d) is (c + e)/2 = (4 + 5)/2 = 4.5.
+
If the first breakpoint is at the end of a metric graph, the value of the breakpoint is the value of the previous point.
For example, if a metric graph has points a, b, c, d, and e, where a = 1, b = 2, c = 3, d = 4, and e = Null, the value of the first breakpoint (that is, point e) is 4.
+
If all points in a metric graph are breakpoints, the values of all these points are still Null, even though you set the value of Interpolation Mode to Average.
For example, if a metric graph has points a, b, c, d, and e, where a = Null, b = Null, c = Null, d = Null, and e = Null, the values of all breakpoints are Null.
