Identify source of a broadcast storm with PRTG

In the recent months we have seen multiple client machines causing broadcast storms on our network, usually from faulty network cards or drivers. At the moment, I try to identify the source of these storms by manually inspecting each SNMP sensor on our switches. Is there a way for PRTG to do the laborious work of sensor inspection and then give me a concise report to identify the switch ports doing the "talking" during a storm?

Dear user

There is no direct solution. However, you can do the following:

1. Set channel limits for the broadcast channel. If you use multi edit, you can set a channel limits for many sensors at the same time. Create a warning limit.

2. Create a PRTG map and use the table for sensor warnings. Filter this table for traffic sensors.

3. Use this map to see the sensors which currently exceed the limit set.
