Charm Statuses

WARNING : it is an work-in-progress article. Do NOT use it in production! Contact Canonical Data Platform team if you are interested in the topic.

The charm follows standard Juju applications statuses. Here you can find the expected end-users reaction on different statuses:

Juju Status Message Expectations Actions
active any Normal charm operations No actions required
waiting any Charm is waiting for relations to be finished No actions required
maintenance any Charm is performing the internal maintenance (e.g. cluster re-configuration) No actions required
blocked any The manual user activity is required! Follow the message hints (see below)
blocked Failed to set up relation The relation between two applications failed to be created. Most probably it is a regression of the recent changes in applications Check Juju debug-log. Increase debug level and reproduce the issue. Report as an issue with debug logs attached (if reproducible). Consider to try previous revision for both applications
