ICMP Ping to monitor surveillance cameras
-
Hello,
I am trying to monitor network security cameras that have no SNMP functionality. I set the objects to use ICMP to determine node status, but the objects don't generate alarms even though they are offline. I tried resetting the alarms using the link below:
Cameras showing 100% ICMP packet loss show as normal and don't have any alarms even after alarm status reset. Any suggestions?

Hi,
Can you please share the textual output of status poll for the node when your camera is online and offline

Ok, next thing to check - it you have a look at Event Log for a node that went from online to offline, what events are there?
-
ID Time Origin time Origin Source Zone DCI Event Severity Message Event tags Root ID 48056062 11.05.2025 06:03:47 11.05.2025 06:03:47 System 4th Fl Stair 2 Default 0 SYS_ICMP_UNREACHABLE Major Node is unreachable by ICMP 48056060 48056061 11.05.2025 06:03:46 11.05.2025 06:03:46 System 4th Fl Stair 2 Default 0 SYS_NODE_CRITICAL Critical Node status changed to CRITICAL NodeStatus 0 48056060 11.05.2025 06:03:46 11.05.2025 06:03:46 System 4th Fl Stair 2 Default 0 SYS_NODE_DOWN Critical Site:Vicina Main 4th Fl Stair 2 is unresponsive - 10.1.102.171 0 So it looks like ICMP status check updates for cameras that were added when they were online.
-
Ok, so SYS_NODE_DOWN event is happening. In Configuration -> Event Processing Policy there should be a default rule named "Show alarm when node is down" that should create alarm when such event happens. Is this rule present and enabled?
-
-
Ok, then an alarm should have been generated. I'd check the alarm log for the node, maybe the alarm was terminated after its creation.

Quite a few of these cameras were added to NetXMS when they were already offline. They then all polled down as they were checking for SNMP. I terminated the first alarms as I knew they didn't have SNMP functionality, but I have been unable to get them to change status based on ICMP either. They have also been offline since addition so I figure that would be why their status is not changing.
