Chapter 4 MM Metrics and Features Configuration : Configuring Health Metric Rules

Configuring Health Metric Rules
Health metric rules have two levels. First you specify the cluster member for which a set of rules will apply. Then you configure the individual rules. You can use either of the following as the basis of the rule:
See Understanding Health Metric Rules for more details.
To Set Up a Health Metric Rule
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.

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.

Click Add. You see a configuration panel.

Click Add. You see fields to define a health metric rule for this cluster member.

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:
To Configure a Health Metric Rule Using Child Member Health Status
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.

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.

To Configure a Health Metric Using Cluster Member Alerts

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.

In the Properties sheet add a property called severity. As the value specify one of critical, warning, or normal.
