NetXMS Support Forum

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:


https://wiki.netxms.org/wiki/Reseting_state_of_all_alarms_and_node_statuses

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

I suspect that this is due to certain cameras being down when they were first added, but I would like for them to show down even if they never polled up when first added.

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?

It is indeed.

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.
