Health Metric Rules
Health metrics are available for cluster members at each level: cluster, machine, process, and agent. The Cluster Overview panel in MM provides information about the overall health of the cluster, and of each of the cluster members.
Health of the cluster is defined in terms of the following three levels:
The colored bulb icons are currently used only in the overall cluster health metric and in alerts. The use of icons is not configurable.
Health metric thresholds are set in the MM.cdd file, which you edit in TIBCO BusinessEvents Studio.
Note the following main points:
- You can configure health metrics for none, some, or all types of cluster members as desired
- When configuring health level thresholds, you do not have to set thresholds for all three health levels (critical, warning, and normal). Use only the ones that are useful to you.
- When configuring rules for more than one health level for a single member, ensure that the conditions have no overlap so that it is clear which condition sets the appropriate health level.
- Cluster Member Paths
The cluster metrics scope is defined using a cluster path: site/cluster/machine/process/inference. - Two Types of Thresholds
You can compute health for a cluster member using either of two methods: Health of Child Cluster Members or Number of Alerts. - Health Metric Rule Examples
Rules can be configured to display a health level indicator on a cluster member based on the health levels of its child members. - Examples Using Alerts
Rules can be configured to display a health level indicator for a cluster member based on the number of alerts received in a time window.
