| # otelcol.exporter.debug | ||
|
|
||
| `otelcol.exporter.debug` accepts telemetry data from other `otelcol` components and writes them to the console (stderr). | ||
| You can control the verbosity of the logs. | ||
|
|
||
| {{< admonition type="note" >}} | ||
| `otelcol.exporter.debug` is a wrapper over the upstream OpenTelemetry Collector `debug` exporter. | ||
| If necessary, bug reports or feature requests are redirected to the upstream repository. | ||
| {{< /admonition >}} | ||
|
|
||
| Multiple `otelcol.exporter.debug` components can be specified by giving them different labels. | ||
|
|
||
| ## Usage | ||
|
|
||
| ```river | ||
| otelcol.exporter.debug "LABEL" { } | ||
| ``` | ||
|
|
||
| ## Arguments | ||
|
|
||
| `otelcol.exporter.debug` supports the following arguments: | ||
|
|
||
| Name | Type | Description | Default | Required | ||
| ---- | ---- | ----------- | ------- | -------- | ||
| `verbosity` | `string` | Verbosity of the generated logs. | `"basic"` | no | ||
| `sampling_initial` | `int` | Number of messages initially logged each second. | `2` | no | ||
| `sampling_thereafter` | `int` | Sampling rate after the initial messages are logged. | `500` | no | ||
|
|
||
| The `verbosity` argument must be one of `"basic"`, `"normal"`, or `"detailed"`. | ||
|
|
||
| ## Exported fields | ||
|
|
||
| The following fields are exported and can be referenced by other components: | ||
|
|
||
| Name | Type | Description | ||
| ---- | ---- | ----------- | ||
| `input` | `otelcol.Consumer` | A value that other components can use to send telemetry data to. | ||
|
|
||
| `input` accepts `otelcol.Consumer` data for any telemetry signal (metrics, | ||
| logs, or traces). | ||
|
|
||
| ## Component health | ||
|
|
||
| `otelcol.exporter.debug` is only reported as unhealthy if given an invalid | ||
| configuration. | ||
|
|
||
| ## Debug information | ||
|
|
||
| `otelcol.exporter.debug` does not expose any component-specific debug | ||
| information. | ||
|
|
||
| ## Example | ||
|
|
||
| This example scrapes Prometheus UNIX metrics and writes them to the console: | ||
|
|
||
| ```river | ||
| prometheus.exporter.unix "default" { } | ||
| prometheus.scrape "default" { | ||
| targets = prometheus.exporter.unix.default.targets | ||
| forward_to = [otelcol.receiver.prometheus.default.receiver] | ||
| } | ||
| otelcol.receiver.prometheus "default" { | ||
| output { | ||
| metrics = [otelcol.exporter.debug.default.input] | ||
| } | ||
| } | ||
| otelcol.exporter.debug "default" { | ||
| verbosity = "detailed" | ||
| sampling_initial = 1 | ||
| sampling_thereafter = 1 | ||
| } | ||
| ``` |
