# Telemetry for backend
|
|
By default, the telemetry is disabled by setting `selector` to `none`, like this
|
|
|
|
```yaml
|
|
telemetry:
|
|
selector: ${SW_TELEMETRY:none}
|
|
none:
|
|
prometheus:
|
|
host: ${SW_TELEMETRY_PROMETHEUS_HOST:0.0.0.0}
|
|
port: ${SW_TELEMETRY_PROMETHEUS_PORT:1234}
|
|
so11y:
|
|
prometheusExporterEnabled: ${SW_TELEMETRY_SO11Y_PROMETHEUS_ENABLED:true}
|
|
prometheusExporterHost: ${SW_TELEMETRY_PROMETHEUS_HOST:0.0.0.0}
|
|
prometheusExporterPort: ${SW_TELEMETRY_PROMETHEUS_PORT:1234}
|
|
```
|
|
|
|
but you can set one of `prometheus` or `so11y` to enable them, for more information, refer to the details below.
|
|
|
|
## Prometheus
|
|
Prometheus is supported as telemetry implementor.
|
|
By using this, prometheus collects metrics from SkyWalking backend.
|
|
|
|
Set `prometheus` to provider. The endpoint open at `http://0.0.0.0:1234/` and `http://0.0.0.0:1234/metrics`.
|
|
```yaml
|
|
telemetry:
|
|
selector: ${SW_TELEMETRY:prometheus}
|
|
prometheus:
|
|
```
|
|
|
|
Set host and port if needed.
|
|
```yaml
|
|
telemetry:
|
|
selector: ${SW_TELEMETRY:prometheus}
|
|
prometheus:
|
|
host: 127.0.0.1
|
|
port: 1543
|
|
```
|
|
|
|
### Grafana Visualization
|
|
Provide the grafana dashboard settings. Check [SkyWalking Telemetry dashboard](grafana.json) config.
|
|
|
|
|
|
## Self Observability
|
|
|
|
SkyWalking supports to collect telemetry data into OAP backend directly. Users could check them out through UI or
|
|
GraphQL API then.
|
|
|
|
Adding following configuration to enable `so11y`(self-observability) related modules.
|
|
|
|
```yaml
|
|
receiver-so11y:
|
|
selector: ${SW_RECEIVER_SO11Y:default}
|
|
default:
|
|
telemetry:
|
|
selector: ${SW_TELEMETRY:so11y}
|
|
# ... other configurations
|
|
```
|
|
|
|
Another example represents how to combine `promethues` and `so11y`. Adding some items in `so11y` to make it happen.
|
|
|
|
```yaml
|
|
telemetry:
|
|
selector: ${SW_TELEMETRY:so11y}
|
|
so11y:
|
|
prometheusExporterEnabled: true
|
|
prometheusExporterHost: 0.0.0.0
|
|
prometheusExporterPort: 1234
|
|
```
|
|
|
|
Then prometheus exporter is listening on `0.0.0.0:1234`.
