Thanks for your comment. I appreciate the help, but I'm still missing something.
I've built a second table and modeled it on the NAS_ALARMS table in the NimsoftSLM database. I am subscribing to all "alarm" messages and am getting data. Some of the columns have correct data compared to the NAS_ALARMS table for the row with the same nimid) but many columns contain "NULL" - time_origin, time_arrival, hostname, nas, etc.
I think I'm getting close, since there are some columns with correct data, but I'd like to get everything that I can. I believe that the $variables in the adogtw profile are based on column names, and I suspect that some of them don't match up.
I'm really looking for a list of the $variables available in adogtw profiles so I can do some more testing and comparison.
