Thanks Alex, works like a charm for me!

Great! Thanks Alex.

It seems that in some versions of Linux (Debian 13 tested by me, but others too...) /var/run/utmp is no longer available.

Some further context I found: https://lists.debian.org/debian-devel/2025/04/msg00014.html

Great job, thanks everyone!

Alessio.

Many thanks Alex,

found images and working on them now...

Hello,

after updating to version 6.2.4 (server, agent, client...), opening one of our custom dashboards causes the server to crash; how can we identify the cause of the problem?

We tried disabling "Scripts.RestrictWriteAccess", but without success.

Thanks in advance,

Alessio.

Just to inform that after upgrade to 6.2.1 (server and web interface) graphs doesn't accomplish time period settings on first opening (eg. time period in properties is set to 1 day and they opens as last hour...).

Manual or auto refresh restores correct time period display settings....

Just to inform that x86_64 linux static agent is missing in today 6.1.1 release (https://netxms.com/download/releases/6.1/nxagent-6.1.1-linux-x86_64-static.tar.gz)...

Thanks so much Filipp, I looked in the documentation but hadn't noticed it,
Alessio.

I successfully deleted the data from the DB, but invalid values continue to arrive from the device...

Is there a way to filter and invalidate them directly as a transformation script?

I tried replacing them with NULL, but they appear as "zero" values in the graphs...

Thanks in advance,
ALessio.

Thanks Alex, i'll give it a try...

Hello, noted an abnormal value on snmp collected value and want to remove it, but from client and webui "Delete value" has no effect, how can we remove it from collected data?

Netxms server, client and webui versions are 6.0.5, thanks in advance...

Agent version 6.0.5 does not fix...

Just upgraded to 6.0.5 (server and webui), now it works as expected! Thanks Victor!

Found db file in %WINDIR%\System32\config\systemprofile\AppData\Local\nxagentd folder, but need enter maintenance, connect to system, stop agent, delete db file, install 5.2.8, start agent and leave maintenance for every win system... will wait for fix!

Thanks anyway, I like netxms since version 0.2.27...

Downgrade from 6.0.4 to 5.2.8 x64 agent (using deploy package) results in "Problem with agent local database: could not open database" major event for me...

The same thing happens to me on all the graphs. It seems to depend not only on the number of data points displayed but also on the size of the viewing windows (the larger the window, the fewer missing data points...).

Hello guys, just upgraded server and webui to 5.1.0 on debian linux 11 with tomcat9 and java17...

Switching to perspective graphs and selecting any returns error:
