# Description This simplifies our OTEL setup by: * Getting rid of some deprecated things. * Using `autoexport` and letting things get configured by the `OTEL_` environment variables. * Removing all the unnecessary config options. ## Checklist Please put an x inside each checkbox to indicate that you've read and followed it: `[ ]` -> `[x]` If this is a documentation change, only the first checkbox must be filled (you can delete the others if you want). - [x] I/we have read the [GoToSocial contribution guidelines](https://codeberg.org/superseriousbusiness/gotosocial/src/branch/main/CONTRIBUTING.md). - [x] I/we have discussed the proposed changes already, either in an issue on the repository, or in the Matrix chat. - [x] I/we have not leveraged AI to create the proposed changes. - [x] I/we have performed a self-review of added code. - [x] I/we have written code that is legible and maintainable by others. - [ ] I/we have commented the added code, particularly in hard-to-understand areas. - [x] I/we have made any necessary changes to documentation. - [ ] I/we have added tests that cover new code. - [x] I/we have run tests and they pass locally with the changes. - [x] I/we have run `go fmt ./...` and `golangci-lint run`.

# Observability
|
|
|
|
These settings let you tune and configure certain observability related behaviours.
|
|
|
|
GoToSocial uses OpenTelemetry. The metrics and trace exporters can be configured using the standard OpenTelemetry SDK environment variables. For a full reference, see [the OpenTelemetry docs](https://opentelemetry.io/docs/languages/sdk-configuration/).
|
|
|
|
## Metrics
|
|
|
|
Before enabling metrics, [read the guide](../advanced/metrics.md) and ensure you've taken the appropriate security measures for your setup.
|
|
|
|
### Tracing
|
|
|
|
To enable tracing, set `tracing-enabled` to `true`.
|
|
|
|
Valid values for `OTEL_TRACES_EXPORTER` are [documented here](https://opentelemetry.io/docs/languages/sdk-configuration/general/#otel_traces_exporter).
|
|
|
|
### Metrics
|
|
|
|
To enable metrics, set `metrics-enabled` to `true`. By default this'll use OTLP to push metrics to an OpenTelemetry receiver.
|
|
|
|
Valid values for `OTEL_METRICS_EXPORTER` are [documented here](https://opentelemetry.io/docs/languages/sdk-configuration/general/#otel_metrics_exporter)
|
|
|
|
For Prometheus, set `OTEL_METRICS_EXPORTER` to `prometheus`. This will start a **second** HTTP server, bound for `localhost:9464` with the OpenTelemetry metrics. You can change this using:
|
|
* `OTEL_EXPORTER_PROMETHEUS_HOST`
|
|
* `OTEL_EXPORTER_PROMETHEUS_PORT`
|
|
|
|
### Authentication
|
|
|
|
If you want to expose the metrics with authentication, you'll need a reverse proxy. You can configure it to proxy to `http://localhost:9464/metrics` and handle authentication in your reverse proxy however you like.
|

|
