We are attempting to create a LUA script to enter data into custom_4 in the NAS pre-processing section. The end result is that we want custom_4 = custom_3 hostname subsystem. Those three items. Custom_3 is created in a alarm_enrichment rule. We attempted to fill custom_4 with an alarm_enrichment, but since the alarm hasn't been put into a database the subsystem value was coming out incorrectly some of the time. We got random data for subsystem.
So that left us to create a LUA script. Can anyone help us with the syntax we would need?
