About Custom Poller

The NNMi Custom Polling feature enables your NNMi administrator to take a proactive approach to network management by gathering additional device information using SNMP MIB Expressions. For example, an NNMi administrator might want NNMi to monitor the Status of COM (communication) ports on all of your Windows servers or determine disk utilization on a specified group of servers.

Using Custom Poller, your NNMi administrator can also configure NNMi to do the following:

Send incidents when certain MIB Expression values are detected.
Map returned MIB Expression values to Thresholds (High State / Low State values) or Comparison Map (State Mapping = the NNMi administrator assigns a State value for each possible Polled Instance value). And include any appropriate State values as part of node Status calculations.

The NNMi Custom Poller feature enables network operators to:

View the list of topology nodes for which additional information is being polled as well as the name of the associated Policy.
View the polling results.
View incidents that are generated by Custom Poller for a MIB Expression.
View Line Graphs for an incident that has a Source Node that is associated with one or more Custom Poller Collections. Click here for more information about Custom Poller Collections.

A Custom Poller Collection defines the information that NNMi should gather (Custom Poll) as well as how NNMi reacts to the gathered data.

Each Custom Poller Collection can have one or more Policies. Each Policy specifies the Node Group from which to gather the additional Custom Poll information. The first time a MIB Expression is validated with discovery information, the results appear in a Polled Instance object. The Polled Instance object is updated whenever a change in State occurs and includes the most recent polled value that caused the State to change.
