NetXMS Forum

Hi Alex, thanks for the hint. I give it a try... Greetings Marco

nxdbmgr actually do this migration for all images - but stock images (there are 9) are deleted by the upgrade process before the actual migration. Current build of both debs and rpms have workaround for that, and it's completely fixed in upcoming 6.2.1.

Hi, The problem is the servlet container version, not Java. The NetXMS 6.2 web client (nxmc-6.2.0.war) is built against the Jakarta Servlet API (jakarta.servlet.* namespace) and requires a container that supports it. You are running Tomcat 9.0.58, which still uses the older javax.servlet.* namespace. Because of that, Tomcat 9 cannot load the application's context listeners, which is exactly the "One or more listeners failed to start" / "Context startup failed" error you see. The ClassCastException about ObjectStreamClass$Caches is a harmless secondary warning. It comes from Tomcat's cleanup routine running on a newer JDK while it tears down the already-failed context - it is not the cause. That is also why switching from JDK 17 to 21 made no difference; the JDK was never the issue. To fix it, deploy the WAR on a container that supports the Jakarta Servlet API: Tomcat 10.1 or later - on Ubuntu use the tomcat10 package, webapps directory /var/lib/tomcat10/webapps. Jetty 11 or later is also fine (Jetty 11/12 support the Jakarta Servlet API). Java 17 or 21 works with either. Do not run it under Tomcat 9 - the javax vs jakarta namespace difference cannot be bridged by a config change or a different JDK.

For XML error - I don't see it in current development version log, so changes are that it's already fixed, pls double-check when v.6.2 is out. For MIB error - I guess MIB compiler is failing on some specific MIB file. You can try removing some of your MIB files until you find which one is causing the issue (you can remove half of them, recomplie, then another half, etc...). Or you can just share your whole MIB file collection.

Make sure that IP address in node's Properties -> Communications is correct. Then run Configuration Poll on that node. If it's still not working, try enabling debug, from Tools -> Server Console: debug syslog 6 and check server log lines when your device sends something.

This is logical flaw in exclusion processing. I've registered an issue: https://github.com/netxms/netxms/issues/3349 Will be fixed as part of 6.2.0 release. Best regards, Victor

Just added physical interface marking in FortiSwitch driver.

Thank you!

We just published patch release 4 for version 6.1. It fixes few important issues: slow data conversion after migration from 5.2 or older versions, and client freeze or slow drawing of stacked charts. Some other small fixes and improvements made their way to the release as well: #3284 (nxdbmgr: migration fails on empty items.transformed_datatype with PostgreSQL) #3290 (Text in Status Explanation unreadable due to it's color) #3291 (Fixed time frame setting not preserved when chart view is pinned or moved between areas) #3298 (DCI image map element tooltip shows only DCI name, not current value) #3306 (Agent list instance discovery not working via gateway node on sensor) #3309 (Add /health endpoint in nxmc/web)

Thanks a lot for your help. I'll give it a try.

Comments are available in open testing track (https://play.google.com/apps/testing/org.netxms.android); 1.0.6 / build 27.

NX-2437 only adds option to change MAC address for interfaces that were created manually, so guess this won't work in your case.

The Portuguese translation is much better now. Congratulations to everyone!

@victor said in Information about the 802.1x status on the switch ports: Just closed issue 3023 (former NX-2821) - will be part of release 6.2.0. Thank you, Victor!

Filipp, Thank you for the clarification I appreciate it. I will look into using Execute.Script

What NetXMS version are you using? Pls show screenshot of properties of a specific subnet in network discovery. Do you use proxies in these zones or server has direct connectivity to nodes in these zones?

I've created tickets covering above-mentioned issues: https://github.com/netxms/netxms/issues/3278 https://github.com/netxms/netxms/issues/3277 https://github.com/netxms/netxms/issues/3276

We suspect it might be a switch configuration problem, yet it functions normally occasionally. We’ll keep an eye on it. Thanks for your help.
