This functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.

This is the query metricset to query from querying API of Promtheus.

Configurationedit

Instant queriesedit

The following configuration performs an instant query for up metric at a single point in time:

- module: prometheus
  period: 10s
  hosts: ["localhost:9090"]
  metricsets: ["query"]
  queries:
  - name: 'up'
    path: '/api/v1/query'
    params:
      query: "up"

More complex PromQL expressions can also be used like the following one which calculates the per-second rate of HTTP requests as measured over the last 5 minutes.

- module: prometheus
  period: 10s
  hosts: ["localhost:9090"]
  metricsets: ["query"]
  queries:
  - name: "rate_http_requests_total"
    path: "/api/v1/query"
    params:
      query: "rate(prometheus_http_requests_total[5m])"

Range queriesedit

The following example evaluates the expression up over a 30-second range with a query resolution of 15 seconds:

- module: prometheus
  period: 10s
  metricsets: ["query"]
  hosts: ["node:9100"]
  queries:
  - name: "up_master"
    path: "/api/v1/query_range"
    params:
      query: "up{node='master01'}"
      start: "2019-12-20T23:30:30.000Z"
      end: "2019-12-21T23:31:00.000Z"
      step: 15s

Fieldsedit

For a description of each field in the metricset, see the exported fields section.

Here is an example document generated by this metricset:
