Just-in-time polling

The SNMP poller’s MIB variable poll list is driven by a Just-In-Time polling algorithm, which ensures that only those MIB variables needed for correlation are polled. For example, if a port monitored for performance data is disabled, or goes down, the SNMP poller automatically removes the relevant MIB variables from the poll list. If the port is re-enabled, or comes back up, the variables are automatically put back onto the MIB poll list.
