Usage

river
loki.echo "LABEL" {}

Arguments

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" { }
