Add missing prometheus rules for persisted events (#8802)
The official dashboard uses data from these rules, but they were never added to the synapse-v2.rules. They are mentioned in this issue: https://github.com/matrix-org/synapse/issues/7917#issuecomment-661330409, but never got added to the rules.

Adding them results in all graphs in the "Event persist rate" section to function as intended.

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.
