See Understanding Health Metric Rules for more details.
Put the most severe health level first Within each clustermember element, the MM server examines the setproperty element that is closest to the top of the file first. When a health metric threshold for a cluster member is met, the application stops and does not process additional thresholds for that member. If you are configuring all three levels, you would put critical first, then warning, and finally normal.See Health Metric Rule Configuration Reference for more details on the settings referenced in this procedure.
1.
2. Open the MM.cdd in the Cluster Deployment Descriptor editor and select the Agent Classes tab
3. Select mm-class (Monitoring & Management) > Health Metric Rule Configurations.
4. Click Add. You see a configuration panel.
7. Click Add. You see fields to define a health metric rule for this cluster member.
8. You can configure health metric rules in two ways. See Two Types of Thresholds for advice on which method to use. Go to one of the following procedures to continue, depending on how you want to configure this rule:This procedure flows from the procedure To Set Up a Health Metric Rule. See Health Metric Rule Configuration Reference for more details on the properties referenced in this procedure.
3. In the Condition Type field, select Child Cluster Member.
4. In the Path field, enter the cluster path of the child cluster member you want to use to compute this health level metric. For example, in computing cluster health you might specify cluster/machine, and for machine health, you might specify cluster/machine/process.
− To use the number of active or inactive child members, add a property called active. Set the value to false to count only inactive members. Set the value to true to count only active members.
− To use the number of child members at a certain health level, add a property called healthLevel and set the value to one of critical, warning, or normal.

9. This procedure flows from the procedure To Set Up a Health Metric Rule. See Health Metric Rule Configuration Reference for more details on the properties referenced in this procedure.
3. In the Condition Type field, select Notification.
4. In the Range field enter a time period in milliseconds. Or enter 0 to specify no time period. If the Threshold number of alerts (of the severity value) is received in the Range period, the health metric is set to the Health Level value. If you specify zero (0) then the health level is changed after receiving the Threshold number without regard to any time window.
6. In the Properties sheet add a property called severity. As the value specify one of critical, warning, or normal.
