Metrics API examples - Select multiple metrics

The GET metrics endpoint provides you the ability to query multiple metrics, along with partial or even full descriptors of metrics.

This example shows how to fetch the descriptors of several metrics of one parent:

CPU idle (builtin:host.cpu.idle)
System load (builtin:host.cpu.load)
CPU usage % (builtin:host.cpu.usage)

For each, we'll query the full descriptors:

Metric key
Display name
Description
Units
Supported entity types
Supported aggregations
Default aggregation
Supported transformations
Dimensions

Configure the request

We have to set the following query parameters:

metricSelector to builtin:host.cpu.(idle,usage,load)
fields to displayName,description,unit,entityType,aggregationTypes,transformations,defaultAggregation,dimensionDefinitions. Note that metricId is omitted here, because it is always presented in the response.

You can get the response in two formats:

JSON: set the Accept header of the request to application/json.
CSV table: set the Accept header of the request to text/csv; header=present. If you're not interested in the header row, use text/csv; header=absent.

To authenticate the request, set the Authorization header of the request to Api-token {your-token}. The token must have the Read metrics (metrics.read) permission.

Curl

Here's the Curl code of the request. Be sure to use the URL of your own environment and a real API token.
