# `loki.echo`

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

You can specify multiple `loki.echo` components by giving them different labels.

## Example

Alloy ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy

```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" { }
```
