Alarms for the dhcp_response probe default to using the subsystemID 184.108.40.206. There is no way to change this within the probe itself.
Our incident routing only uses Private subsystem ID's starting with 3.4 to route alarms to the correct group in our service desk system.
I believe I can use a NAS script combined with a Pre-Processing rule to catch alarms that have a subsystemID of 220.127.116.11 and change it a different ID starting with 3.4.
How would I set this up?
