Dear Community members :wave: ,

:warning: Promtail (default agent for Grafana Loki :grafana: :grafana_loki:) will be End-Of-Life by March 2026.

Source of Announcement: Official Promtail Page

It means that:

  • No releases of any security patches
  • No Bug fixes or new improvements

The only way to move forward is to replace Promtail with Grafana Alloy :alloy:

I have created this video tutorial that explain a very detailed step-by-step instructions on how to migrate your your existing Promtail configuration files (for you Grafana Loki deployments) to Grafana Alloy :alloy: :grafana_loki: :grafana: and be able to keep using Loki and not re-create your dashboards, queries.

This tutorial is also for those users who are new to Grafana Alloy :alloy: and can easily get started to deploy it on their machine with minimal effort.

Link to the video:

:light_bulb: All the important links are available in the video description.

The video contains the following sections:

  • Why Promtail is going EOL?
  • Intro. to Grafana Alloy (advantages, features)
  • Installation (Setting up Env.)
  • Migration Setup for your Loki :grafana_loki:
  • Understanding Configuration
  • Advanced Debugging/Troubleshooting
