# Enabling metrics and graphs for your Matrix server (optional)
|
||
|
|
|
||
|
|
It can be useful to have some (visual) insight in the performance of your homeserver.
|
||
|
|
|
||
|
|
You can enable this with the following settings in your configuration file (`inventory/host_vars/matrix.<your-domain>/vars.yml`):
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
matrix_prometheus_enabled: true
|
||
|
|
|
||
|
|
matrix_synapse_metrics_enabled: true
|
||
|
|
matrix_prometheus_node_exporter_enabled: true
|
||
|
|
|
||
|
|
matrix_grafana_enabled: true
|
||
|
|
matrix_grafana_anonymous_access: true
|
||
|
|
matrix_grafana_default_admin_user: yourname
|
||
|
|
matrix_grafana_default_admin_password: securelongpassword
|
||
|
|
```
|
||
|
|
|
||
|
|
## What does it do?
|
||
|
|
|
||
|
|
Name | Description
|
||
|
|
-----|----------
|
||
|
|
`matrix_prometheus_enabled`|Prometheus is a time series database. It holds all the data we're going to talk about.
|
||
|
|
`matrix_synapse_metrics_enabled`|Enables metrics specific to Synapse
|
||
|
|
`matrix_prometheus_node_exporter_enabled`|Node Exporter is an addon of sorts to Prometheus that collects generic system information such as CPU, memory, filesystem, and even system temperatures
|
||
|
|
`matrix_grafana_enabled`|Grafana is the visual component. It shows the dashboards with the graphs that we're interested in
|
||
|
|
`matrix_grafana_anonymous_access`|By default you need to login to see graphs. If you want to publicly share your graphs (e.g. when asking for help in [`#synapse:matrix.org`](https://matrix.to/#/#synapse:matrix.org?via=matrix.org&via=privacytools.io&via=mozilla.org)) you'll want to enable this option.
|
||
|
|
`matrix_grafana_default_admin_user`<br>`matrix_grafana_default_admin_password`|By default Grafana creates a user with `admin` as the username and password. If you feel this is insecure and you want to change it beforehand, you can do that here
