(NNMi) Support Tip: Force a MIB variable to a different type in custom poller


In Network Node Manager i-series (NNMi) the Custom Poller can be used to configure the collection and monitoring of a MIB expression value. The value calculated depends on the types of the MIB variables in the MIB expression but will be either

  .The actual calculated or collected value or
  .The rate of change of the value from one collection to the next.

For instance, collecting a MIB variable that is defined as an 'Integer' and represents 'the number of logged in users' will provide the actual value. However, collecting the number of packets transmitted on an interface which is defined as a 'Counter' will provide the difference between the previous value and the current value. This is done because in nearly all cases the rate of change i.e. x number of packets / second is more meaningful than the actual number of packets at each collection point.

The variable types that define each collection are :

Actual value:


Rate of Change:


There are occasions when a variable needs to be collected in the other form than its declaration would imply. How can this be done?
