Important: The SNMP Table monitor template should NOT be assigned to a device like other monitors in the library. Instead, it is a monitor template designed to be configured and assigned to a role or subrole prior to running a discovery scan. Discovery would then create individual instances of SNMP Monitors on devices based on their assigned roles during a scan.

This monitor allows you to create individual SNMP monitors for each row in a table on a device (e.g., interface, disk, fan) based on specific discovery conditions. While this monitor can be assigned directly to a device, it is designed to be configured and assigned to a role or subrole prior to running a discovery scan. When a device is discovered and assigned a role/subrole with the SNMP table monitor applied, individual SNMP active monitors are then applied to each table row on that device.

Provide a unique name and description for the monitor, then configure the following options.

  • Use in Rescan. Enable this option if the monitor is to be applied during rescan. Please note, this option is independent of whether or not the device has a role or subrole assigned that would apply this monitor.
  • SNMP Timeout. Specify the amount of time WhatsUp Gold waits for a reply from the device.
  • Number of SNMP retries. Set the number of times that collector attempts SNMP request.
Monitoring conditions
  • Status OID. This OID is the column to be used by the monitor to determine the state of that row. Click the icon to the right of the data entry field to launch the SNMP MIB Browser where you can select an OID.
  • Operator. This is the value type test to be made against the value returned by the MIB element retrieved using the Status OID plus index. The options are as follows:
    • Is one of. Select this option to determine if the MIB element value matches one of the values entered.
    • Range of values. Select this option to determine if the MIB element value falls within the high and low values entered.
    • Less than. Select this option to determine if the MIB element value is less than the test value entered (numerically or lexigraphically, depending on syntax).
    • Greater than. Select this option to determine if the MIB element value is greater than the test value entered (numerically or lexigraphically, depending on syntax).
    • Contains one of. Select this option to determine if the MIB element value contains one or more of the test strings entered.
    • Rate of change. Select this option to determine if the rate of change in units per second is greater that the test value entered.

Please note, the subsequent data entry field in the dialog is dependent upon and corresponds to your Value Type selection.

  • Monitor state if the value matches. Specify if the conditions set matching the returned value should result in the monitor reporting as Up or Down.
  • Comment OID. This (optional) OID is the column used when forming the name of the monitor for that row. Click the icon to the right of the data entry field to launch the SNMP MIB Browser where you can select an OID.
  • Index OID. This (optional) OID is used to gather the indexes of the rows to consider when creating a monitor for each row instance. Click the icon to the right of the data entry field to launch the SNMP MIB Browser where you can select an OID.
Discovery conditions
  • Object ID. This OID is used to get a column value which indicates if that row should receive a monitor. Click the icon to the right of the data entry field to launch the SNMP MIB Browser where you can select an OID.
  • Value Types. This is the value type test to be made against the value returned by the Object OID. Please note, Rate of Change is not supported.
    • Is one of. Select this option to determine if the MIB element value matches one of the values entered.
    • Range of values. Select this option to determine if the MIB element value falls within the high and low values entered.
    • Less than. Select this option to determine if the MIB element value is less than the test value entered (numerically or lexigraphically, depending on syntax).
    • Greater than. Select this option to determine if the MIB element value is greater than the test value entered (numerically or lexigraphically, depending on syntax).
    • Contains one of. Select this option to determine if the MIB element value contains one or more of the test strings entered.
  • Create monitor when the value. Specify if the monitor(s) should be created with the value either Matches or Doesn't Match.
