# Enabling synapse-usage-exporter for Synapse usage statistics (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
|
|
|
|
## Adjusting the playbook configuration
|
|
|
|
To enable synapse-usage-exporter, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```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
|
|
```
|
|
|
|
### Adjusting the synapse-usage-exporter URL
|
|
|
|
By default, this playbook installs synapse-usage-exporter on the `matrix.` subdomain, at the `/report-usage-stats/push` path (https://matrix.example.com/report-usage-stats/push). This makes it easy to install it, because it **doesn't require additional DNS records to be set up**. If that's okay, you can skip this section.
|
|
|
|
By tweaking the `matrix_synapse_usage_exporter_hostname` and `matrix_synapse_usage_exporter_path_prefix` variables, you can easily make the service available at a **different hostname and/or path** than the default one.
|
|
|
|
Example additional configuration for your `inventory/host_vars/matrix.example.com/vars.yml` file:
|
|
|
|
```yaml
|
|
# Change the default hostname and path prefix
|
|
# These variables are used only if (`matrix_synapse_usage_exporter_proxying_enabled: true`)
|
|
matrix_synapse_usage_exporter_hostname: sue.example.com
|
|
matrix_synapse_usage_exporter_path_prefix: /
|
|
```
|
|
|
|
## Adjusting DNS records
|
|
|
|
If you've changed the default hostname, **you may need to adjust your DNS** records to point the synapse-usage-exporter domain to the Matrix server.
|
|
|
|
See [Configuring DNS](configuring-dns.md) for details about DNS changes.
|
|
|
|
If you've decided to use the default hostname, you won't need to do any extra DNS configuration.
|
|
|
|
## Installing
|
|
|
|
After configuring the playbook and potentially [adjusting your DNS records](#adjusting-dns-records), run the playbook with [playbook tags](playbook-tags.md) as below:
|
|
|
|
<!-- NOTE: let this conservative command run (instead of install-all) to make it clear that failure of the command means something is clearly broken. -->
|
|
```sh
|
|
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
|
|
```
|
|
|
|
The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
|
|
|
|
`just install-all` is useful for maintaining your setup quickly ([2x-5x faster](../CHANGELOG.md#2x-5x-performance-improvements-in-playbook-runtime) than `just setup-all`) when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed. Note these shortcuts run the `ensure-matrix-users-created` tag too.
