# GrayLog Input Plugin

The Graylog plugin can collect data from remote Graylog service URLs.

Plugin currently support two type of end points:-

- multiple  (e.g. `http://[graylog-server-ip]:9000/api/system/metrics/multiple`)
- namespace (e.g. `http://[graylog-server-ip]:9000/api/system/metrics/namespace/{namespace}`)

End Point can be a mix of one  multiple end point  and several namespaces end points

Note: if namespace end point specified metrics array will be ignored for that call.

## Configuration

```toml
# Read flattened metrics from one or more GrayLog HTTP endpoints
[[inputs.graylog]]
  ## API endpoint, currently supported API:
  ##
  ##   - multiple  (e.g. `http://<host>:9000/api/system/metrics/multiple`)
  ##   - namespace (e.g. `http://<host>:9000/api/system/metrics/namespace/{namespace}`)
  ##
  ## For namespace endpoint, the metrics array will be ignored for that call.
  ## Endpoint can contain namespace and multiple type calls.
