synapse/contrib/prometheus/README.md

This directory contains some sample monitoring config for using the 'Prometheus' monitoring server against synapse.

To use it, first install prometheus by following the instructions at

http://prometheus.io/

for Prometheus v1

Add a new job to the main prometheus.conf file:

  job: {
    name: "synapse"

    target_group: {
      target: "http://SERVER.LOCATION.HERE:PORT/_synapse/metrics"
    }
  }

for Prometheus v2

Add a new job to the main prometheus.yml file:

  - job_name: "synapse"
    metrics_path: "/_synapse/metrics"
    # when endpoint uses https:
    scheme: "https"

    static_configs:
    - targets: ["my.server.here:port"]

An example of a Prometheus configuration with workers can be found in metrics-howto.md.

To use synapse.rules add

  rule_files:
    - "/PATH/TO/synapse-v2.rules"

Metrics are disabled by default when running synapse; they must be enabled with the 'enable-metrics' option, either in the synapse config file or as a command-line option.
