When logged into the Orion Web console I goto the manage nodes tab > add node > and try to add the Orion Server via SNMP, but it does not work. Have tried restarting the server and snmp service as well. Was working and has all of the sudden stopped.
In the add node dialog does the Validate SNMP validate or fail? I'm assuming what you mean by watch orion via snmp is that you want the NPM to monitor itsself is that correct? Also are you seeing anything in the evenlogs when you try to validate the snmp?
