Resolve Inconsistencies between State and Status
At times, differences between State and Status values might occur. These differences generally indicate the system is busy processing large volumes of data, perhaps due to a significant configuration change or network outage.
Note the following:
- NNMi updates State before Status. A delay in Status updates might be due in part to the processing required for root cause analysis performed by the Causal Engine.
- As NNMi completes this processing, the consistency of State and Status is restored.
- Associated incidents might also be delayed during this time.
- Status updates can run behind by the amount of time listed for Delay Processing Input in the System Information dialog's Causal Engine tab.
If the consistency of State and Status is not restored, NNMi enables you to correct the State or Status inconsistencies for each of the following:
Resolve State or Status Inconsistencies on a Single Node
To correct either an unexpected State or inconsistent Status value on a node:
1. Navigate to the node view or map of interest and right-click the node
2. Select Polling → Configuration Poll
3. Select Polling → Status Poll
To correct inconsistent Status values on a node for which the State value is correct:
1. Navigate to the nodes view or map of interest and right-click the node
2. Select Polling → Status Poll
Resolve State or Status Inconsistencies on Multiple Nodes
To correct State or Status inconsistencies on multiple nodes, use the nnmnoderediscover.ovpl command.
The nnmnoderediscover.ovpl command, when used with the –fullsync option, enables you to re-synchronize the nodes specified.
The re-synchronization process performs the following for each node:
- Rediscovers the node.
- Reloads and refreshes the monitoring configuration for the node.
- Reanalyzes State and Status for the node.
To re-synchronize a single node:
nnmnoderediscover.ovpl –node hostname –fullsync
To re-synchronize all nodes in a file:
nnmnoderediscover.ovpl –file filename –fullsync
Tip To quickly generate the file needed for this command-line tool,consider using the nnmnodegroup.ovpl command-line tool. See the nnmnodegroup.ovpl Reference Page.
To re-syncrhonize all the nodes on an NNMi management server:
nnmnoderediscover.ovpl -all –fullsync
If a large number of nodes (for example, thousands) are being re-synchronized, it is recommended that you re-synchronize these nodes during off-peak periods, when possible.
NNMi must remain running until the re-sychronization is complete. If NNMi is stopped before the re-synchronization is complete, run the nnmnoderediscover.ovpl command again and allow the re-synchronization to complete.
For more information, see nnmnoderediscover.ovpl.
