2.6.3 Node group status
NNMi determines the status of a node group using one of the following algorithms:
-
Set the node group status to match the most severe status of any node in the node group. To use this approach, select the Propagate Most Severe Status check box on the Status Configuration form.
-
Set the node group status using the thresholds set for each target status. For example, the default threshold for the target status of Minor is 20%. NNMi sets the status of the node group to Minor when 20% (or more) of the nodes in the node group have Minor status. To use this approach, clear the Propagate Most Severe Status check box on the Status Configuration form. You can change the percentage thresholds for the target thresholds on the Node Group Status Settings tab of this form.
Because status calculations for large node groups can be resource-intensive, the default for calculation of node group status is set to off for new installations of NNMi. You can enable status calculation with the Calculate Status check box on the Node Group form for each node group.
