The Any passive monitor receives all type-specific (SNMP, Syslog, Windows Event Log) traps and events sent from the device to which it is assigned. This monitor can be useful when you are trying to pinpoint the specific trap and coinciding MIB for which you want to WhatsUp Gold to listen and monitor. As the monitor gathers traps and events, this data is added to the respective log (SNMP Trap Log, Syslog Entries, Windows Event Log). You can scan the report entries to find the specific trap that you would like to monitor, and create a passive monitor for that specific trap.
If, after running the monitor for some time, you do not notice the trap for which you are looking, the MIB may not be loaded in the WhatsUp Gold MIB directory. If this is the case, import the MIB. For more information, see Using the SNMP MIB Manager.
Important: Because of the volume of data gathered when this monitor is enabled, we strongly advise that this monitor only be used for troubleshooting purposes. If this monitor is enabled for more than short periods of time, you run the risk of flooding your database and compromising the performance of WhatsUp Gold.
As the monitor has been pre-configured for you, to use it, you are required only to assign it to the device for which you researching traps and events. For more information, see Assigning passive monitors.
It is important that you remember to remove the monitor when you have completed troubleshooting because of the monitor's potential to fill up the WhatsUp Gold database.
