Querying Time Series Objects¶
Function¶
This API is used to query the time series objects that can be monitored in the system. You can specify a namespace, name, dimension, and resource ID (format: resType_resId). You can also specify the start position and the maximum number of returned records for a pagination query.
URI¶
POST /v2/{project_id}/series
Parameter | Mandatory | Type | Description |
---|---|---|---|
project_id | Yes | String | Project ID obtained from IAM. Generally, a project ID contains 32 characters. |
Parameter | Mandatory | Type | Description |
---|---|---|---|
limit | No | String | Maximum number of returned records. Value range: 1-1000. Default value: 1000. |
offset | No | String | Start position of a pagination query. The value is a non-negative integer. |
Request Parameters¶
Parameter | Mandatory | Type | Description |
---|---|---|---|
series | Yes | Array of QuerySeriesOptionParam objects | Array for querying time series objects. |
Parameter | Mandatory | Type | Description |
---|---|---|---|
namespace | Yes | String | Namespace of time series objects. Value range: PAAS.CONTAINER, PAAS.NODE, PAAS.SLA, PAAS.AGGR, or CUSTOMMETRICS. PAAS.CONTAINER: namespace of application time series objects. PAAS.NODE: namespace of node time series objects. PAAS.SLA: namespace of SLA time series objects. PAAS.AGGR: namespace of cluster time series objects. CUSTOMMETRICS: namespace of custom time series objects. |
metric_name | No | String | Time series name. Length: 1 to 255 characters. Values: cpuUsage: CPU usage. cpuCoreUsed: used CPU cores. Custom time series names. |
dimensions | No | Array of DimensionSeries objects | List of time series dimensions. You can call the /v2/{project_id}/series API to query the time series dimension list by namespace and metric_name. |
Parameter | Mandatory | Type | Description |
---|---|---|---|
name | No | String | Dimension name. |
value | No | String | Dimension value. |
