26.5.9 Event correlation: ScheduledMaintenance
With NNMi, you can suppress the monitoring of unusable nodes. To do this, use the Out of Service mode. Refer to 21.26 Scheduling outages about how to configure Out of Service maintenance in advance.
- Note
NNMi suppresses SNMP traps sent from devices that are in the Out of Service mode.
If your organization is using ScheduledMaintenance correlation, you can use a list of systems that will go offline together.
Check whether ScheduledMaintenance correlation is used in NNM.
In the NNMi console, from the Configuration workspace, choose Object Groups > Node Groups.
Create a node group for each node set in the NNM maintenance list. Configure the node groups so that they can be used as view filters.
For maintenance, from the Inventory workspace in the NNMi console, choose Nodes.
To filter the view for a given node group, use the Node Group Filter Configuration selector at the top of the window.
Select all nodes, and then choose Actions, Management Mode, and Out of Service.
After the maintenance has been completed, select a node, and then choose Actions, Management Mode, and Manage.
