otelcol.exporter.logging

otelcol.exporter.logging accepts telemetry data from other otelcol components and writes them to the console.

This component writes logs at the info level. The logging config block must be configured to write logs at the info level.

Multiple otelcol.exporter.logging components can be specified by giving them different labels.

Example

This example scrapes prometheus unix metrics and writes them to the console:

prometheus.exporter.unix { }

prometheus.scrape "default" {
	targets    = prometheus.exporter.unix.targets
	forward_to = [otelcol.receiver.prometheus.default.receiver]
}

otelcol.receiver.prometheus "default" {
	output {
		metrics = [otelcol.exporter.logging.default.input]
	}
}

otelcol.exporter.logging "default" {
	verbosity           = "detailed"
	sampling_initial    = 1
	sampling_thereafter = 1
}
