# Setting up synapse-usage-exporter (optional)
|
|
|
|
[synapse-usage-exporter](https://github.com/loelkes/synapse-usage-exporter) allows you to export the usage statistics of a Synapse homeserver to this container service and for the collected metrics to later be scraped by Prometheus.
|
|
|
|
Synapse does not include usage statistics in its Prometheus metrics. They can be reported to an HTTP `PUT` endpoint 5 minutes after startup and from then on at a fixed interval of once every three hours. This role integrates a simple [Flask](https://flask.palletsprojects.com) project that offers an HTTP `PUT` endpoint and holds the most recent received record available to be scraped by Prometheus.
|
|
|
|
Enabling this service will automatically:
|
|
|
|
- install the synapse-usage-exporter service
|
|
- re-configure Synapse to push (via HTTP `PUT`) usage statistics information to synapse-usage-exporter
|
|
- re-configure [Prometheus](./configuring-playbook-prometheus-grafana.md) (if Prometheus is enabled), to periodically scrape metrics from synapse-usage-exporter
|
|
- add a new [Grafana](./configuring-playbook-prometheus-grafana.md) dashboard (if Grafana is enabled) containing Synapse usage statistics
|
|
|
|
## Quickstart
|
|
|
|
Add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file and [re-run the installation process](./installing.md) for the playbook:
|
|
|
|
```yaml
|
|
matrix_synapse_usage_exporter_enabled: true
|
|
|
|
# (Optional) Expose endpoint if you want to collect statistics from outside (from other homeservers).
|
|
# If enabled, synapse-usage-exporter will be exposed publicly at `matrix.example.com/report-usage-stats/push`.
|
|
# When collecting usage statistics for Synapse running on the same host, you don't need to enable this.
|
|
# You can adjust the hostname and path via `matrix_synapse_usage_exporter_hostname` and `matrix_synapse_usage_exporter_path_prefix`.
|
|
# matrix_synapse_usage_exporter_proxying_enabled: true
|
|
```
