# `prometheus.exporter.statsd`

The `prometheus.exporter.statsd` component embeds the [`statsd_exporter`](https://github.com/prometheus/statsd_exporter) for collecting StatsD-style metrics and exporting them as Prometheus metrics.

At least one of `listen_udp`, `listen_tcp`, or `listen_unixgram` should be enabled. Refer to the [`statsd_exporter` documentation](https://github.com/prometheus/statsd_exporter#metric-mapping-and-configuration) more information about the mapping `config file`. Make sure the kernel parameter `net.core.rmem_max` is set to a value greater than the value specified in `read_buffer`.

### Blocks

The `prometheus.exporter.statsd` component doesn’t support any blocks. You can configure this component with arguments.

## Exported fields

The following fields are exported and can be referenced by other components.

Expand table

| Name      | Type                | Description                                               |
|-----------|---------------------|-----------------------------------------------------------|
| `targets` | `list(map(string))` | The targets that can be used to collect exporter metrics. |

For example, the `targets` can either be passed to a `discovery.relabel` component to rewrite the targets’ label sets or to a `prometheus.scrape` component that collects the exposed metrics.

The exported targets use the configured [in-memory traffic](../../../../get-started/component_controller/#in-memory-traffic) address specified by the [run command](../../../cli/run/).

## Component health

`prometheus.exporter.statsd` is only reported as unhealthy if given an invalid configuration. In those cases, exported fields retain their last healthy values.

## Debug information

`prometheus.exporter.statsd` doesn’t expose any component-specific debug information.

## Debug metrics

`prometheus.exporter.statsd` doesn’t expose any component-specific debug metrics.

## Example

The following example uses a [`prometheus.scrape` component](/docs/grafana-cloud/send-data/alloy/reference/components/prometheus/prometheus.scrape) to collect metrics from `prometheus.exporter.statsd`:

Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```alloy
prometheus.exporter.statsd "example" {
  listen_udp            = ""
  listen_tcp            = ":9125"
  listen_unixgram       = ""
  unix_socket_mode      = "755"
  mapping_config_path   = "mapTest.yaml"
  read_buffer           = 1
  cache_size            = 1000
  cache_type            = "lru"
  event_queue_size      = 10000
  event_flush_threshold = 1000
  event_flush_interval  = "200ms"
  parse_dogstatsd_tags  = true
  parse_influxdb_tags   = true
  parse_librato_tags    = true
  parse_signalfx_tags   = true
}

// Configure a prometheus.scrape component to collect statsd metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.statsd.example.targets
  forward_to = [prometheus.remote_write.demo.receiver]
}

prometheus.remote_write "demo" {
  endpoint {
    url = "<PROMETHEUS_REMOTE_WRITE_URL>"

    basic_auth {
      username = "<USERNAME>"
      password = "<PASSWORD>"
    }
  }
}
```

Replace the following:

- *`<PROMETHEUS_REMOTE_WRITE_URL>`* : The URL of the Prometheus `remote_write` compatible server to send metrics to.
- *`<USERNAME>`* : The username to use for authentication to the `remote_write` API.
- *`<PASSWORD>`* : The password to use for authentication to the `remote_write` API.
