+* If the rule group is marked as **Available**, it is working as expected.
+* If the rule group is marked as **Degraded**, one or more rules in the group are not working as expected. This can be due to the rule query being throttled, or to other issues that may cause the rule evaluation to fail. Expand the status entry for more information on the detected problem, as well as suggestions for mitigation or for further troubleshooting.
+* If the rule group is marked as **Unavailable**, the entire rule group is not working as expected. This can be due the configuration issue (for example, the Azure Monitor Workspace can't be detected) or due to internal service issues. Expand the status entry for more information on the detected problem, as well as suggestions for mitigation or for further troubleshooting.
+* If the rule group is marked as **Unknown**, the entire rule group is disabled or is in an unknown state.

+## Disable and enable rule groups 
+To enable or disable a rule, select the rule group in the Azure portal. Select either **Enable** or **Disable** to change its status.
