NetXMS Support Forum

What is your NetXMS Server version exactly?
Can you show reporting server log for the moment when - if you are on Linux, this command will show it
journalctl -u netxms-reporting.service
Also note, that if you changed some parameters in SMTP-Text notification channel properties you need to restart reporting server for the changes to have effect

Your server is v. 6.1.1, but web UI still stays on 6.0.x.

Have you replaced the .war file in Tomcat/Jetty with the new one (https://netxms.com/download/releases/6.1/nxmc-6.1.1.war)?

If yes, sometimes Tomcat/Jetty is hesitant with switching to new file, try removing .war file, restarting Tomcat/Jetty, putting .war file and restarting again.

Database query planning is a separate mystery on its own. Anyways, developers restored additional index as it was before v. 6.0, that will be included in next patch release.

Еще одной штуки не хватает, когда этот тикет закроется тогда можно будет прикручивать:

А как сконфигурированы прокси - они прописаны в свойствах ноды, или ноды в удаленных офисах выделены в зоны? Если второе, то прокси тоже нужно поставить тоже в эти зоны.

Да, сейчас мы читаем только нормализованное значение, а нужны raw. Сделал тикет: https://github.com/netxms/netxms/issues/3199

raw_dci_values table is just a cache of most recent DCI values. You can just truncate it and proceed with the upgrade:

TRUNCATE TABLE raw_dci_values;

Possible case could be a locking of some server thread. You can capture server threads when you see delays in working with the server from the GUI, here's the script: https://github.com/netxms/netxms/blob/master/tools/capture_netxmsd_threads.sh
Script should be executed 3 times with 20-30 second interval. It needs gdb and netxms-dbg packages installed on the system.

Also to check - on netxms server node there should be Server: Number of Processed Events (based on internal Server.TotalEventsProcessed metric) - just to verify that there we no sudden spikes in event quantity.
In overall there's quite a few metrics there, e.g. Server QueueSize ones, it's worth checking them for any big spikes.
If you don't have Server.ImportConfigurationOnStartup set to Always, you might not have the most recent template with above mentioned DCIs, you may want to import them from /usr/share/netxms/templates/netxms_server.xml

Hi,

Please show value of
DefaultNotificationChannel.SMTP.Text
from Configuration->Server Configuration.

If above is set to "SMTP-Text", pls show configuration of SMTP-Text notification channel. If above is set to something else, pls show configuration of that notification channel.

Can you show a screenshot to understand what exactly is in which language?

Pls show output of the following from debug console:

sh st
sh th
sh qu

What are the overall specs of the server? What are CPU and memory for a few days?

I've created a ticket for this: https://github.com/netxms/netxms/issues/3195

This should be fixed in the current version

Sorry, this was overlooked for a while. First guess is that there are some issues with syncer thread. It's not visible in show threads, as there's just one syncer threads. In debug console there's

netxmsd: sh sy
Last run at .........: 16.Apr.2026 15:22:58
Last run time .......: 1 ms
Average run time ....: 119 ms
Max run time ........: 132 ms
Min run time ........: 0 ms

And System -> NetXMS Server -> Server Performance has metrics for it, specifically Server.SyncerRunTime.Last. Pls check if this metric looks reasonable.

Slow log opening might indicate problems with DB performance, DB might need tuning. What are the specs on DB VM, is it dedicated to NetXMS or a shared database? How's CPU consumption and IO stats? How big is the database on disk?
You can also use mysql subagent to collect stats about DB operation - https://netxms.org/documentation/adminguide/database-monitoring.html#mysql

Which database you are using?
