5.0 quality score

We run a couple of automated
scans to help you access a
module's quality. Each module is
given a score based on how well
the author has formatted their
code and documentation and
modules are also checked for
malware using VirusTotal.

Please note, the information below
is for guidance only and neither of
these methods should be considered
an endorsement by Puppet.

grafana/promtail — version 2.1.0 Aug 31st 2021


Build Status License

Deploy and configure Grafana's Promtail on a node.


Promtail is an agent which ships the contents of local logs to a private Loki instance or Grafana Cloud. It is usually deployed to every machine that has applications needed to be monitored.

It primarily:

  1. Discovers targets
  2. Attaches labels to log streams
  3. Pushes them to the Loki instance.

Currently, Promtail can tail logs from two sources: local log files and the systemd journal (on AMD64 machines only).


The simplest way to get started with this module is to add include promtail to a manifest and create your config settings in Hiera. Additional details and examples are contained in


This module is documented via pdk bundle exec puppet strings generate --format markdown. Please see for more info.

Changelog is generated prior to each release via pdk bundle exec rake changelog. This process relies on labels that are applied to each pull request.


At the moment, this module only supports Linux. Future versions will support additional OS's including Windows.


Pull requests are welcome! A Vagrantfile is also included in this repository that can be used during development.

Module Release

Follow the steps below to tag a new release and push to The Forge using GitHub Actions.

  1. Ensure that all closed PRs are labeled appropriately.
  2. Create a "Release Prep" PR with the label "maintenance" containing changes made by the following:
    1. Bump the module version (X.Y.Z) in metadata.json as appropriate based on closed PRs since the previous release. (i.e. "backwards-incomptible" is an X "release", "feature" is a Y release, and "bugfix" is a Z release)
    2. Run pdk bundle exec puppet strings generate --format markdown. Any missing documentation will result in a failed pipeline.
    3. Run pdk bundle exec rake changelog. Any unlabeled PRs will result in a failed pipeline.
  3. Once the PR is merged, navigate to Actions --> Publish Module --> Run workflow --> select the main branch, and Run workflow.
