Can Netxms automatically traceroute the given IP address and add all traces into its databases and show connection status accordingly.
Automatic Graphs - like IP neighbourhood may be generated showing status background.
this way One can easily identify why a particular node is unreachable, where is the problem just we simply troubleshoot through tracert DOS command, can similar type of functionality be provided in netxms.

I am quite hopeful that you shall consider this request in subsequent 1.2.10 release.

It will add great functionality to netxms discovery and IP neighbourhood graphs

Thanks!
