Why are the SNMP traps sent out from the snmpgtw probe to a trap receiver not sending all of the data?  No alarms will ever send values for the custom 1-5 fields; the varbind is present, but the string text field is blank.  There is a NAS AO preprocessing rule configured to add values for the custom 1-5 fields before the event is created as an alarm. The snmpgtw probe is listening for a standard "alarm" queue as is set by default as well.
UIM 8.51
hub 7.93
snmpgtw 1.40
snmpcollector 3.437hf
nas 9.00
The "alarm" subject field is the initial alarm received by the NAS and will not contain any pre-processing rules the NAS runs on it. What would be suggested to do is to repost the alarm using an Auto-Operator Profile rule, for example:

1. Create an AO profile with the setting below in NAS probe
-Action type: repost
-Subject : AddCustomFields (this is example subject name)
-NMS Probe Name: logmon (use what ever filter would work for you, in this case this is reposting all logmon messages)

2.Now use AddCustomFields as Subject(s) under Setup in snmpgtw probe configuration.
