Right now i am working at several things tu customize NPM. I Build a custom property called Customer for nodes in the database that allows me to user X, Y and Z only to see the nodes that are theirs, but with no traps Syslog event. Theres no way to add some relate propery withi the traps.
I dont know what to do whith this issue.
You shouldn't need to build a customer property or anything else. They should only see the traps and syslog for the devices in which they have rights to see
