Network discovery
-
Hello,
i would like to use NetXMS primary to make LAN maps for our remote offices / locations. I have question for Network Discovery. I have setup active / passive as well, correct SNMP community and IP ranges. I had successes to add 3 locations, but after several hours remaining locations are not being added, even after using option from menu to start manual scan.
Do i need to use proxy for remote scan ?
Current setup is show in attached image.
Any help is welcome

Proxies should not be required, if your servers is able to communicate to these subnets directly.
Passive discovery requires that there's netxms agent or SNMP agent on the remote machines - this way we are getting neighbors from arp tables (and not sure from where exactly in case of SNMP).
For active scanning nodes should reply either ICMP, SNMP or netxms agent - if none is happening we can not discover a node.You can try temporarily increasing netxms server debug log
nxadm -c "debug 7"and manually launching a scan of a subnet to better understand what's happening.
Or, alternatively you can try capturing network traffic to that subnet with tcpdump, this can also give some insight.
