Querying Metrics

Function

This API is used to query the metrics that can be monitored in the system. You can query specific metrics by specifying a namespace, metric 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.

Calling Method

For details, see Calling APIs.

URI

POST /v1/{project_id}/ams/metrics

Table 1 Path Parameters

Parameter

Mandatory

Type

Description

project_id

Yes

String

Project ID obtained from IAM. Generally, a project ID contains 32 characters.
Table 2 Query Parameters

Parameter

Mandatory

Type

Description

type

No

String

Metric query mode.

limit

No

String

Maximum number of returned records. Value range: 1–1000. Default value: 1000.

Minimum: 0

Maximum: 4

start

No

String

Start position of a pagination query. The value is a non-negative integer.

Request Parameters

Table 3 Request header parameters

Parameter

Mandatory

Type

Description

X-Auth-Token

Yes

String

User token obtained from IAM.

Content-Type

Yes

String

Content type, which is application/json.

Enumeration values:

  • application/json
Table 4 Request body parameters

Parameter

Mandatory

Type

Description

inventoryId

No

String

Resource ID, which must be in the format of resType_resId. Enumerated values of resType: host, application, instance, container, process, network, storage, and volume.When type (a URI parameter) is inventory, this parameter instead of metricItems is used for associated metric queries.

metricItems

No

Array of QueryMetricItemOptionParam objects

If the value of type in the URI is not inventory, metrics are queried based on the information carried by metricItems.
Table 5 QueryMetricItemOptionParam

Parameter

Mandatory

Type

Description

dimensions

No

Array of Dimension objects

List of metric dimensions.

metricName

No

String

Metric name. Length: 1 to 255 characters. Value range: cpuUsage, cpuCoreUsed, and other basic metrics provided by AOM. cpuUsage: CPU usage. cpuCoreUsed: used CPU cores. Custom metrics.

namespace

Yes

String

Metric namespace. Values: PAAS.CONTAINER: namespace of component, instance, process, and container metrics. PAAS.NODE: namespace of host, network, disk, and file system metrics. PAAS.SLA: namespace of SLA metrics. PAAS.AGGR: namespace of cluster metrics. CUSTOMMETRICS: default namespace of custom metrics.

Enumeration values:

  • PAAS.CONTAINER

  • PAAS.NODE

  • PAAS.SLA

  • PAAS.AGGR

  • CUSTOMMETRICS
