## Metrics server
|
||||||
|
|
||||||
|
Anubis includes support for [Prometheus-style metrics](https://prometheus.io/docs/introduction/overview/), allowing systems administrators to monitor Anubis' performance and effectiveness. This is a separate HTTP server with metrics, health checking, and debug routes.
|
||||||
|
|
||||||
|
Anubis' metrics server is configured with the `metrics` block in the configuration file:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
metrics:
|
||||||
|
bind: ":9090"
|
||||||
|
network: "tcp"
|
||||||
|
```
|
||||||
|
|
||||||
|
If you want to bind metrics to a Unix socket, make sure to set the network to `unix` and add a socket mode:
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
metrics:
|
||||||
|
bind: "/tmp/anubis_metrics.sock"
|
||||||
|
network: unix
|
||||||
|
socketMode: "0700" # must be a string
|
||||||
|
```
