loki.echo
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
alloy
loki.echo "LABEL" {}
Arguments
loki.echo
accepts no arguments.
Exported fields
The following fields are exported and can be referenced by other components:
Name | Type | Description |
---|---|---|
receiver | LogsReceiver | A value that other components can use to send log entries to. |
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:
alloy
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" { }
Compatible components
loki.echo
has exports that can be consumed by the following components:
