loki.echo

BETA: This is a beta component. Beta components are subject to breaking changes, and may be replaced with equivalent functionality that cover the same use case.

loki.echo receives log entries from other loki components and prints them to the process’ standard output (stdout).

Multiple loki.echo components can be specified by giving them different labels.

Usage

river

loki.echo "LABEL" {}

Arguments

loki.echo accepts no arguments.

Exported fields

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

Component health

loki.echo is only reported as unhealthy if given an invalid configuration.

Debug information

loki.echo does not expose any component-specific debug information.

Example

This example creates a pipeline that reads log files from /var/log and prints log lines to echo:

river

local.file_match "varlog" {
  path_targets = [{
    __path__ = "/var/log/*log",
    job      = "varlog",
  }]
}

loki.source.file "logs" {
  targets    = local.file_match.varlog.targets
  forward_to = [loki.echo.example.receiver]
}

loki.echo "example" { }
