Configuring a Health Metric Rule with the Child Member Health status

Use either the number of active or inactive child members or their health level to configure a health metric rule.

Procedure

  1. In the Health Metric Rule ID field, enter a descriptive name to identify the rule.
  2. In the Health Level field, select the health level that the rule will indicate.
  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.
  5. In the Threshold field enter the threshold percentage.
    If the percentage of child cluster members that match the criteria specified meets or exceeds this threshold, then the health level of the parent cluster member is set to the Health Level field value.
  6. In the Properties sheet add one or both of the following properties to set the criteria for counting child members:
    • 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.
  7. Repeat this procedure to configure this cluster member’s thresholds for remaining health levels (critical, warning, or normal), as desired.
  8. Save.
  9. If you have finished configuration, start the emonitor project using the modified CDD file.
    This starts the MM server.
