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

accepts no arguments.
Exported fields

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" { }
