NNMi uses the following statuses when monitoring its health:

NNMi Overall Health Status
Status	Description
Warning	Indicates performance issues that are not significantly affecting NNMi.
Minor	Indicates problems that might result in out of date data. For example, an NNMi component, such as State Poller might be out of synch because it is operating outside of expected ranges.
Major	Indicates problems that are significantly affecting the NNMi management server's operations, but are not yet critical. Major Status usually indicates that some action is required. For example, a trap threshold is reached.
Critcal	Indicates NNMi is not functioning. For example, NNMi is out of memory, all database connections are lost, or a major NNMi component has failed.

Use the Tools → NNMi Self-Monitoring Graphs to view information about NNMi components and their usage. NNMi Self-Monitoring Graphs include:
- SNMP Trap Pipeline Rate
- SNMP Trap Forwarding Rate
- Discovery Progress
- SNMP Requests
Tip Use the SNMP Requests Graph to tune Communication Configuration settings.
NNMi administrators can use the command line on any NNMi management server to generate a report about NNMi health. See the nnmhealth.ovpl Reference Page for more information.
