Is it already possible to generate an alert based on text contained in the Trap Details field in the Trap Viewer? Can you help me please?
yes. See my post on this thread: http://thwack.solarwinds.com/ideas/1139 (and vote it up)
more information -- you'll have to try the SQL query in the database viewer to make sure it generates the correct list of nodes with the alert on them.
