Register various alarm rules for your Kafka Cluster to receive alarms under specific conditions. In the Rules list, you can activate or deactivate rules using each activation toggle button. It is recommended not to deactivate important alarm rules. On the right, you can see the alarm rules list for each tab. Also, by clicking on an alarm row in the list, you can view the detailed contents of the alarm rule on a drawer.

System Rules
When you added your cluster, mKC has pre-registered alarm rules regarding important monitoring items in basic cluster management. These System Rules cannot be deleted or modified, but you can prevent the generation of alarm history using the activation button.
Admin Rules
You can view Admin Rules which the users with admin permissions created. Users who do not have admin permissions cannot modify or delete Admin Rules.
Personal Rules
The logged-in user can view the Personal Rules they have created.
Deleting Rules
You can delete alarm rules that are not needed anymore. Once deleted, alarms will no longer be generated even if the conditions are met. However, existing alarm history will still be visible during the retention period. To delete a rule, click on the [Trash Can Icon] on the right side of the alarm row, or click on the alarm row to open drawer with the details, then the [Trash Can Icon] at the top right.
