impl MetricsManager

Source

pub fn boot_metrics_service(listen_addr: String)

Source

async fn metrics( __arg0: ExtraQuery<Filter>, __arg1: Extension<Registry>, ) -> impl IntoResponse

Gather metrics from the global registry and encode them in the Prometheus text format.

The handler accepts the following query parameters to filter metrics. Note that include and exclude should not be used together.

  • /metrics (without filter)
  • /metrics?include=foo (include one metric)
  • /metrics?include=foo&include=bar (include multiple metrics)
  • /metrics?exclude=foo&exclude=bar (include all but foo and bar)

One can specify parameters by configuring Prometheus scrape config like below:

- job_name: compute-node
  params:
    include: ["foo", "bar"]
