Every application has a general application-level health check, which aggregates the statuses of all core kubernetes components and generates a digestable summary for human consumption. These are viewable in the application switcher in the admin console, or by running:
plural watch <app-name>
This will generate output like:
Application: console (0.5.35) READY plural admin console Components Ready: 15/15 Ready Components: - service/console :: Ready - service/console-headless :: Ready - service/console-master :: Ready - service/console-replica :: Ready - service/plural-console :: Ready - service/plural-console-repl :: Ready ...
If a component is not ready, it will also generate hints to kubectl commands which might help debug further.
