<![CDATA[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?

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.

I'd check the alarm log for the node, maybe the alarm was terminated after its creation.

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?

So it looks like ICMP status check updates for cameras that were added when they were online.

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.

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