|
|
||
| This receiver accepts [metrics](https://druid.apache.org/docs/latest/operations/metrics) data from the [HTTP Emitter](https://druid.apache.org/docs/latest/configuration/#http-emitter-module) of Apache Druid. | ||
|
|
||
| ## Prerequisites | ||
|
|
||
| Apache Druid cluster needs to be configured to enable metrics, see [Enabling Metrics](https://druid.apache.org/docs/latest/configuration/#enabling-metrics) and the [HTTP Emitter Module](https://druid.apache.org/docs/latest/configuration/#http-emitter-module). | ||
|
|
||
| ## Configuration | ||
|
|
||
| The following configuration options are supported: | ||
|
|
||
| - `endpoint` (default = 0.0.0.0:9000) HTTP service endpoint for the line protocol receiver | ||
| - `metrics_path` (default = `/services/collector/metrics`) The path accepting Apache Druid metrics. | ||
| - `logs_path` (default = `/services/collector/logs`) The path accepting Apache Druid logs. | ||
| - `cluster_name` (default = `default`) The default name of Druid cluster. Note that the [HTTP Emitter](https://druid.apache.org/docs/latest/configuration/#http-emitter-module) of Apache Druid `28.0.0` doesn't include cluster name information in metrics. | ||
|
|
||
| The full list of settings exposed for this receiver are documented in [config.go](config.go). | ||
|
|
||
| Example: | ||
|
|
||
| ```yaml | ||
| receivers: | ||
| apachedruid: | ||
| endpoint: 0.0.0.0:9000 | ||
| ``` | ||
| ## Metrics | ||
| Details about the metrics produced by this receiver can be found in [metadata.yaml](./metadata.yaml) |
