<![CDATA[Devices not being added after scan]]>I have configured a remote agent trough the agent tunnel and linked the agent to a container in a zone. I have setup network discovery for the zone and selected the agent as the proxy node. In the agent logs, I can see the scan is being activated and lots of devices are found with both icmp and snmp scan, but nodes are not being added. Anyone who can guide me where to look for issues?

  • Active discovery targets in Network Discovery
  • Communication page from properties of the zone object (under Entire Network)

Here is the log from a node with 192.168.1.205, which does not get added.

Agent should be specified in Zone's properties on Communications page. Zones are found under "Entire network" (Network perspective).
From agent's side it's configuration should have
EnableProxy = yes
EnableSNMPProxy = yes

If issue still persist, please grep the log for 2-3 specific IP addresses so that we have full process for each of them.

You can enable debug, in server debug console:
debug poll.discovery 6

Then check server log, there should be some messages on what's happening.

To disable debug:
debug poll.discovery -1
