7.2.2 What Can NNMi Monitor?
The State Poller Service monitors each discovered interface, address, and SNMP agent that is designated to be actively monitored in your management domain. State Poller can also be configured to provide Card, Chassis, Node Sensor, Physical Sensor, and Router Redundancy Group monitoring.
- Note
-
In most cases, polling only connected interfaces provides sufficiently accurate root-cause analysis. Extending the set of monitored interfaces can impact polling performance.
If NNMi is monitoring a hypervisor network environment, it will also monitor additional objects, including the following:
-
Hypervisors
-
Virtual Machines (VMs) that are hosted on hypervisors
-
Virtual Switches
-
Uplinks (represented as interface objects)
- Tip
-
- Ensure that VMware Tools is installed on your virtual machines and then use the Virtual Machines Node Group provided by NNMi to enable fault polling for the IP addresses associated with your VMs. This is a recommended practice to ensure that NNMi can identify any VM nodes where the underlying Virtual Machine has been deleted or moved to a hypervisor NNMi does not manage. For more information about enabling fault polling, see "Default Settings for Monitoring" in the NNMi Help for Administer.
