NetXMS Support Forum

Hello,

In order to monitor remote networks over a bandwidth limited link I passively SNMPwalk the ip destination MIB and detect if the network is active (function returns 1 if network is find 0 otherwise). I would like to link this to a node so I can display on a manual network map, and have it light up green when available and red otherwise. However, when I create an unmanaged node to accomplish this, the background is always blue with a question mark in the icon. When I trigger an event "SYS_NODE_DOWN" the node turns red as desired, however, upon triggering "SYS_NODE_UP" it goes back to the blue border and question mark. Is there any way to overwrite this default behavior such that the unmanaged node will appear green when directed?

Thank You,
Brent

Why not use "ping" to monitor?
In nodes properties, you can disable all options but "ICMP pings" in "Polling" tab.

You can also use ProxyAgent.
Add node without NetXMS/SNMP agent polling, use EXEC(yourscript.sh) in DCI and change polling intervall
yourscript.sh must be added to the ProxyAgent doing the polls..

Hi Borgso, thanks for the response.

The issue is our WAN link is very limited (32kbs), but there are many nodes on the other side we would like status on. So inducing more traffic with multiple pings is not an option for us.

I will look into use of ProxyAgent as you suggest.

Thanks,
Brent
