NetXMS Support Forum

Thank you so much for taking the time to reply to my post and offer your help!

I'm trying to set up reliable alarm and recovery notifications for my monitoring setup, and I was hoping you could advise me on the best way to achieve this using **native EPP rule configurations** in NetXMS 6.1.3, without needing to write custom NXSL scripts.

The core functionality I need is:
1.  **Alarm deduplication**: Only send one notification for the same issue within a 2-hour window, to avoid spamming
2.  **Proper alarm-recovery pairing**: Ensure recovery notifications are only sent for issues that actually triggered an alarm earlier
3.  **Targeted device filtering**: Only send notifications for devices I've marked as "focused" (not all devices in the system)

I did try writing my own NXSL scripts to implement this, but I got stuck on one critical part: I couldn't figure out how to design a **universal key value that works across all types of events and alarms** (similar to what I've seen others refer to as an "alarm key") to properly link alarm events with their corresponding recovery events. Without this, I can't reliably ensure that a recovery notification is only sent if an alarm notification was actually sent for that specific issue first.

I've looked through the EPP rule settings but I'm not sure how to combine these three requirements correctly using the built-in options. Could you walk me through how to configure the EPP rules to achieve this, or point me to the relevant documentation sections?

Thanks again for your time and generosity.
