NetXMS Support Forum

Hi,

Have you noticed that SSH is not working on v6.0.2?

I've configured the same SSH port on both sites (including the default port), but I'm still getting the following error:

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

Type Exception Report

Hell0!

Trying to build NetXMS for testing, currently everything works and is pulled but one thing - User Sessions tab, it gives an error "Cannot get list of active user sessionss: Operation cannot be completed due to agent error".

Server is built using a default docker file, agent is installed on 2 linux machines, one with static agent, another one was built from source.

The only error I found was in debug:

2026.02.27 11:33:32.780 *D* [comm.cs.1          ] Received message CMD_GET_TABLE (32)2026.02.27 11:33:32.780 *D* [comm.cs.1          ] Requesting table "System.ActiveUserSessions"

I wonder what can I look into to troubleshoot.

I'm running into some issues. For some reason, I'm not able to see the devices when running network discovery. I have set everything up properly, including the network credentials. Can anyone please help me see the devices after scanning?

Using the desktop client version 5.2.8  server is debian using timescaledb.  If I am using the exact OID for that device shouldn't it only list for  that device and not others ? for example the OID is for a switch vendor but the tool is also being listed for cameras with a completely different OID.  I have also tried using attributes and templates and these also do not work. It would be nice to be to apply tools by container or using filter scripts

если на сервере в его окне DCI кликнуть на этот параметр и отобразить график (line chart) - он рисуется корректно, как раньше, тут не поменялось ничего после обновления.

Quote from: Filipp Sudanov on February 26, 2026, 09:05:11 AMОк, спасибо. Покажите, плс, первую страницу настроек этого DCI.

не понял.  параметры DCI, отображаемые в этом line chart где сломалось ?

Ок, спасибо. Покажите, плс, первую страницу настроек этого DCI.
