Adding and editing a SNMP Active Monitor

The Simple Network Management Protocol (SNMP) is the protocol governing network management and monitoring of network devices and their functions. In this monitor, WhatsUp Gold utilizes SNMP to gather specific information about the functions of SNMP-enabled network devices by querying a device to verify that it returns an expected value. Depending on the state you choose, the monitor is considered either up or down according to the returned value.

To add a new SNMP active monitor:

1. From the WhatsUp Gold web interface, go to Admin > Monitors. The Monitor Library dialog appears.
2. Click the Active tab. The Active Monitor list appears.
3. Click New. The Select Active Monitor Type dialog appears.
4. Select SNMP Monitor, then click OK. The Add SNMP Monitor dialog appears.
5. Enter the appropriate information in the following fields:
   • Name. Enter a name for the active monitor. This name displays in the Active Monitor Library.
   • Description. Enter a short description for the monitor. This description displays next to the monitor in the Active Monitor Library.
6. Click browse (...) to select the appropriate SNMP object in the MIB Browser.
7. Select Check Type.
8. Complete the check type detailed information.

   When Constant Value is selected:

   • Value. Depending on the Object ID you selected, enter the appropriate value.
   • If the value matches, then the monitor is: select Up or Down.

   When Range of Values is selected:

   • Low Value. Depending on the Object ID you selected, enter the appropriate value.
   • High Value. Depending on the Object ID you selected, enter the appropriate value.

   When Rate of Change in Value is selected:

   • Rate of Change (in variable units per second). Enter the desired value.
   • If the value is above the rate, then the monitor is: select Up or Down.
