Check configuration -> Event processing policy.
The way NetXMS is built is that when something happenins (interface went down, threshold reached, etc...) it creates events (log of these can be seen in Event Log). Reaction to events is defined in Event processing policy (make sure you click "save" button when working with it).

Thank you brother, yes, here is the configuration;
One more question, how do I remove old history alerts if I disable these policies midway through? (history alert package install update etc)
