Child Cluster Member  Computes the threshold using the health level of specified child cluster members.
Notification  Computes the threshold as a number of alerts of a specified severity for the cluster member, during a given time period.
See Two Types of Thresholds for more details on this choice.
This field appears if you choose Child Cluster Member in the Condition Type field. Enter the cluster path that defines which child cluster members to use in computing this health metric. For example, in computing cluster health you might specify cluster/machine, and for machine health, you might specify cluster/machine/process.
See Cluster Member Paths for more on defining paths.
You can use any child of the cluster member specified in the Cluster Member ID field of the cluster member node. It doesn’t have to be an immediate child, and it doesn’t have to be the same child member in rules you configure for the other health levels for this cluster member.
In the Properties sheet add a property called active and set it to true or false. This defines whether the active or inactive state of the cluster members specified in this path is used in computing the status.
Optionally, add a property called healthLevel and set it to normal, warning, or critical. When you do this, the Threshold percentage applies only to those specified child members whose health level matches this setting (and that are active or inactive as specified in the active property).
The health level rule is defined as a percentage (as defined in the Threshold field) of all child cluster members of the specified type that are active or inactive (as specified in the active property) and optionally: that are at the specified health level.
This field appears if you choose Notification in the Condition Type field. Enter the number of milliseconds to be used as a range. The Threshold count is reset at the end of each range period.
When used for a Child Cluster Members Condition Type  Defines a percentage. Enter a value between 0 and 100 as desired. When the number of child cluster members that satisfy the rule criteria meets or exceeds the percentage, the health indicator specified for the health level specified in this rule displays.
When used for a Notification Condition Type  Defines a number of alerts. When the number of alerts notification/property@severity alerts for the enclosing clustermember meets or exceeds this value, within the time period specified in the range setting, the health indicator specified for the health level specified in this rule displays. Note  If either the Threshold or Range settings is not defined, then a single alert for the cluster member causes the health indicator to change.
The active and health level properties are used only when computing the health level using child cluster members. You can use both active and healthlevel properties in one rule, although there may be few use cases for using both properties.
