Yes. You have to have

SubAgent = ping.nsm

in nxagentd.conf.

That helped, thank you.

Did you load ping subagent on proxy?

Negative. This is the agent config:

# Log File
LogFile = /var/log/nxagentd
DebugLevel = 9

MasterServers = lab.lab-network.example
ServerConnection = lab.lab-network.example

EnableProxy = Yes
EnableSNMPProxy = Yes
EnableSNMPTrapProxy = Yes
EnableTCPProxy = Yes

Does that mean that the ICMP subagent is required for active discovery?

If updated the server, and changed from Raspberry to a Ubuntu, but the problem still exists:

probe-user@probe-box:~$ nxagentd -v

That's all the updates i can do. Building it myself from the GIT sources is above my Linux knowledge.  :-)

Thanks, understood.
I will try again with Ubuntu proxy and report back.

Unfortunately, the version for Raspberry is lacking behind.

I experience problems with active subnet discovery which I can't make sense of. I allready set the logging to Level 9 on the server and Level 7 on the proxy. The "probe" i use is a raspberry in a different location, tunneling in. Everything works fine for nodes which I added manual.

However, active discovery does not discover anything, and seems not too run at all:


2019.07.17 02:47:48.841 *D* [poll.discovery     ] Starting active discovery check on range 10.85.27.5 - 10.85.27.252 via proxy probe-box-085-Q21 [596]
2019.07.17 02:47:49.150 *D* [poll.discovery     ] Finished active discovery check on range 10.85.28.5 - 10.85.27.252 via proxy probe-box-085-Q21 [596]

That doesn't look right, does it? The subnet is wrong in the second line.

I tested several ways to enter the 10.85.27.0/24 into the Active Discovery Targets (see GUI-setting-Discovery.png):

Subnet 10.85.27.0/24
Range 10.85.27.1 - 10.85.27.254
Range 10.85.27.5 - 10.85.27.252

The error does not disappear, and no nodes are added.

On the proxy probe, the log shows:

Any ideas where to look?
