Observability Team Updates - Week 49-52

Hi everyone!

Below you’ll find the updates from the team for weeks 49 through 52.

The Team

The observability team at Canonical consists of Dylan, Jose, Leon, Luca, Pietro, Ryan, and Simme. Our goal is to provide you with the best open-source observability stack possible, turning your day-2 operations into smooth sailing.

COS Lite

COS Lite is a light-weight, highly-integrated observability suite, powered by python operators and running on Juju. Find more information on charmhub or go straight to github.


In addition, we’ve continued working on our upstream contribution to Grafana Loki. The PR is now up and ready for initial review!


  • Fix an issue that prevented bundling dashboards created in Grafana 9 (#155)
  • Simplify the catalogue charm by eliminating the need to account for path prefixes (#2, #6)
  • Fix link propagation in the catalogue library (#3, #158)
  • Fix issue where dashboards propagated by COS Config would still get dropdowns injected.
  • Fix issue where Loki would go into error state on removal (#219)

Have a great week! :snowman: :snowflake:
