Trap Watch

The Trap Watch tool allows you to monitor and examine details of incoming notifications (traps and inform requests) from SNMP agents. Unlike the other tools currently provided in MIB Views, the Trap Watch tool is not tied to an individual agent, but rather an individual port or ports. Thus, the Trap Watch tool is displayed in a separate window from the other tools.

To open the Trap Watch tool, select the Tools|Trap Watch menu item. You'll be asked to select a port to monitor for incoming notifications, as shown below. SNMP agents normally send traps to port 162, the default.

Trap Port Configuration
Figure - Trap Port Configuration
On Unix platforms, including Mac OS X, administrator priviledges are required to bind (listen) to port 162. On these platforms, a separate daemon is provided, called nmtrapd, whose only job is to listen to incoming traps and forward them on to connected clients. This daemon is compatible with Scotty's similar daemons, called straps in 2.x and nmtrapd in 3.x. See Trap Reflector Daemon Installation for more information.

You can have multiple Trap Watch tool windows open, each monitoring different ports. After selecting a port, the Trap Watch tool will open and will display traps as they're received.

Click the Settings button icon to change the port configuration for the Trap Watch window.

Click the Clear button icon to clear the event log.

Select an event from the Event Summary list to display details for that event -- that is, all of the values provided in the variable bindings, including values extracted from the instance identifiers for tabular data.

Tip: Click on a column header to sort events by time, source, event name (snmpTrapOID value), or event description.
