Prometheus

Connects today

The metrics format most services and exporters already speak.

Point Prometheus remote-write at Plexus and every series you already scrape lands next to your hardware's telemetry.

What Plexus reads

  • Samples sent over remote-write, with their labels

What it does not read

  • Anything you do not forward. Plexus does not scrape your targets

Connecting it

  1. 1Add a remote_write block with your Plexus URL and API key

Tutorial

Send Prometheus metrics to Plexus with remote_write

Add one block to prometheus.yml. Everything Prometheus scrapes is forwarded to Plexus, next to your hardware's telemetry.

  1. 1

    Create an API key with write access at app.plexus.company/api.

  2. 2

    Add this to prometheus.yml. source_id is required: it names the source these series land under.

    yaml
    remote_write:
  - url: https://gateway.plexus.company/api/v1/write?source_id=prometheus-01
    authorization:
      credentials: plx_xxx
  3. 3

    Reload Prometheus, or restart it.

What you’ll see: prometheus-01 appears in Plexus. Each series comes in under its metric name, with its labels as tags. Stale markers are dropped rather than stored as gaps.

Connect it, and the dashboards build themselves from the first data that lands.
