# ECS Monitoring Metrics

#### Function

This section describes metrics reported by ECS to Cloud Eye as well as their namespaces and dimensions. You can use APIs provided by Cloud Eye to query the metrics of the monitored object and alarms generated for ECS.

#### Namespace

SYS.ECS

#### Metrics

Metric | Name | Description | Value Range | Remarks
--- | --- | --- | --- | ---
cpu_util | CPU Usage | This metric is used to show CPU usages (%) of monitored objects. | 0% to 100% | ECS monitored NOTE: The metrics collected using OTC Tools are accurate.
mem_util | Memory Usage | This metric is used to show memory usages (%) of monitored objects. | 0% to 100% | ECS monitored NOTE: This metric is unavailable if the image has no OTC Tools installed.
disk_util_inband | Disks Usage | This metric is used to show disk usages (%) of monitored objects. | 0% to 100% | ECS monitored NOTE: This metric is unavailable if the image has no OTC Tools installed.
disk_read_bytes_rate | Disk Read Bandwidth | This metric is used to show the number of bytes read from the monitored object per second (byte/s). | ≥ 0 | ECS monitored
disk_write_bytes_rate | Disk Write Bandwidth | This metric is used to show the number of bytes written to the monitored object per second (byte/s). | ≥ 0 | ECS monitored
disk_read_requests_rate | Disk Read IOPS | This metric is used to show the number of read requests sent to the monitored object per second (requests/second). | ≥ 0 | ECS monitored
disk_write_requests_rate | Disk Write IOPS | This metric is used to show the number of write requests sent to the monitored object per second (requests/second). | ≥ 0 | ECS monitored
network_incoming_bytes_rate_inband | Inband Incoming Rate | This metric is used to show the number of incoming bytes received by the monitored object per second (byte/s). | ≥ 0 | ECS monitored
network_outgoing_bytes_rate_inband | Inband Outgoing Rate | This metric is used to show the number of outgoing bytes sent by the monitored object per second (byte/s). | ≥ 0 | ECS monitored
network_incoming_bytes_aggregate_rate | Outband Incoming Rate | This metric is used to show the number of incoming bytes received by the monitored object per second (byte/s) at the virtualization layer. | ≥ 0 | ECS monitored NOTE: This metric is unavailable if SR-IOV is enabled.
network_outgoing_bytes_ aggregate_rate | Outband Outgoing Rate | This metric is used to show the number of outgoing bytes sent by the monitored object per second (byte/s) at the virtualization layer. | ≥ 0 | ECS monitored NOTE: This metric is unavailable if SR-IOV is enabled.

ib_card_state

InfiniBand NIC status

This metric is used to monitor the status of an InfiniBand NIC on a high-performance h2 ECS to ensure proper InfiniBand NIC running.

The system periodically checks the NIC status and returns check results using value 0 or 1.

- 0: The system is running properly. That is, the InfiniBand NIC is functional.
- 1: The system is not running properly. That is, the InfiniBand NIC malfunctions.

0 or 1

ECS monitored

NOTE:

Only Mellanox EDR 100 GB single-port InfiniBand NICs are supported.

The image based on which the target ECS is created must have OTC Tools installed. Otherwise, the Memory Usage and Disk Usage metrics are unavailable. For details about how to install the OTC Tools, visit https://github.com/UVP-Tools/UVP-Tools/.

#### Dimension

Key | Value
--- | ---
instance_id | Specifies the ECS ID.
