Deploy the SNMPTD probe.
Select the settings button (top left) and "Enable Generic" bottom left of the settings window. [You might also like to bump up the log level/size while your here in case of debug]
Then on the generic tab of the settings page tick the "Convert to Nimsoft alarm" box.
In later updates I might go a little further into the options here but for now lets just go ahead and use the defaults.
I use a free windows tool in my testing to generate traps which the monitor picks up. If your SNMP device is correctly configured to point to the SNMPTD probe you should see entries here when you click play (when and how many depends on the interval traps are being sent)
You can see the top trap has a different icon to the rest. That's because I had a profile in place for "Generic" when that trap was received.
Again in the main config window under V2 & V3 traps create a new profile:
Name it something like "Generic" and set the "Trap Object Identifier" to . [dot, period] and tick the "Convert to Nimsoft Alarm".
Applying the probe settings should now start to generate traps -> Nimsoft Alarms - possibly a lot so use with care.
