Monitor any OID

You can monitor all SNMP traps. By setting “SNMP Trap (All)” in advance, you can perform common actions based on those settings when receiving an SNMP trap. This is useful when you have not clearly decided which traps to monitor, or when you want to monitor all SNMP traps and register incidents.

Note:

The “SNMP Trap (All)” and “SNMP Trap (Optional)” settings can be used together. If used together, the “SNMP Trap (optional)” setting takes precedence.

  1. Click the [Inventory] tab, and doubleclick the device for which you want to set up a monitor.

  1. Click the button. at the bottom left, and then click “Catch All Trap (All).”

  1. Enter any monitor name.

  1. Click [Triggers], then click [Catch All Trigger Alert].

  1. Specify the alert policy.

  1. Click [Save].

With the above settings, alerts will be issued for all SNMP traps received from monitored devices.
