NetXMS Support Forum

Oh, thanks!
I realized that I used netxms-websvc-6.0.4.war instead of nxmc-6.0.4.war.
I actually wanted to deploy the nxmc-6.0.4.war file.
Thanks for telling me!

When I try to deploy netxms-websvc-6.0.3.war on Tomcat 10 and access the webpage, I receive the following error:

I had the same problem, but after executing the satements it did work.

Hi,
Thank you for helping. The problem was, that i use 1 node for HP iLO which has 8 Network Interfaces, one of the Network interfaces has the same IP Address of the ESXi VMWare Host which is installed on this Server. So the IP-Adress is a duplicate and the new Node was deleted.
I changed the Server Property to: NetworkDiscovery.MergeDuplicateNodes = 0
Now I think it works!
Thank you so much for helping!

Bye
Woody

Hi,
I updated NetXMS:
root@netxms:~# netxmsd -v
NetXMS Server Version 3.7.116 Build 3.7-116-g133064d484 (UNICODE)
NXCP: 5.53.1.29 (AES-256, Blowfish-256, 3DES, AES-128, Blowfish-128)
Built with: g++ (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0
The problem still exists in this version.

I collected the logs and filtered only the lines with the name of the node.

Hi,
it does disappear after some time. After a server restart the node was still there.
NetworkDiscovery.MergeDuplicateNodes is enabled.
But the node is no duplicate. I searched for the ip adress and it didn't find anything.


Best regards,
Woody

Hello,
I have the problem that a node gets automatically deleted after some time.
Here is some information about my system:

Server: Ubuntu 18.04.5 LTS (GNU/Linux 4.15.0-130-generic x86_64)
NetXMS version:
root@netxms:~# netxmsd -v
NetXMS Server Version 3.7.95 Build 3.7-95-ga7a4f1d5c7 (UNICODE)
NXCP: 5.53.1.29 (AES-256, Blowfish-256, 3DES, AES-128, Blowfish-128)
Built with: g++ (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0

The name of the node is: Haas HP DL380 Gen9 (iLO)

When I serach for the name in the log file i see the following errors:

Hello,
is this still up to date? Or should I rather use the nxdbmgr export command?

Best reagrds,
