Hi all! 
We would like to announce a new 12-factor app feature, delivered with the 1.11 release of paas-charm. This feature allows you to create your own custom Grafana dashboards and Loki and Prometheus alert rules.
This can easily be done now by creating a directory called cos_custom with the required assets alongside charmcraft.yaml to be packed with charm.
Important Note
Some apps already do this by overriding the get_cos_dir() method in their charm. The release of this feature will break apps doing it this way. Please follow the docs to see how to implement the custom COS directories using the new way.
See the full documentation for this feature here:
