Querying Alarm Rules

Function

This API is used to query alarm rules. You can specify the paging parameters to limit the number of query results displayed on a page. You can also set the sorting order of query results.

URI

GET /V1.0/{project_id}/alarms

Parameter description

**Table 1** Parameter description
Parameter	Mandatory	Description
project_id	Yes	Specifies the project ID. For details about how to obtain the project ID, see Obtaining a Project ID. Minimum: 1 Maximum: 64 Regular expression matching: ^[a-zA-Z0-9-]{1,64}$

**Table 2** Parameter description
Parameter	Type	Description
alarms	Array of objects	Specifies the alarm rule list. For details, see Table 3.

**Table 3** Query parameter description
Parameter	Mandatory	Type	Description
start	No	String	Specifies the first queried alarm to be displayed on a page. The value is alarm_id.
limit	No	Integer	Range: 1 to 100 (default) This parameter is used to limit the number of query results.
order	No	String	Specifies the result sorting method, which is sorted by timestamp. The default method is desc. asc: The query results are displayed in the ascending order. desc: The query results are displayed in the descending order.

Example
Request example 1: Query the current alarm rule list.
```
GET https://{Cloud Eye endpoint}/V1.0/{project_id}/alarms
```
Request example 2: Query the alarm rule list. Start by setting alarm_id to al1441967036681YkazZ0deN and retain 10 records in the descending order of time stamps.
```
GET https://{Cloud Eye endpoint}/V1.0/{project_id}/alarms?start=al1441967036681YkazZ0deN&limit=10&order=desc
```
