NetXMS Forum

Hi, Hopping over from https://www.netxms.org/forum/general-support/netxmsd-hangs-during-startup/ to say thanks for the pointer towards alarm_events which solved my issue! I also had a huge number of rows in this table, and found the culprit in a misconfigured event processing policy which was catching too many events. You may also have something similar. In my case I discovered it by looking at alarms with very high repeat counts. If you open the alarm details it will show the EPP rule which created it.

Could be firewall issue, some limits on server that prevent process from accepting connections. It was some time ago, so I hope it's resolved. If not, what's the output of netstat -lptun on your server?

@filipp-sudanov said in Connection with NetXMS server was lost with NetXMC 4.4.2 version: This error was fixed, fix will be included in patch release that should be out this week. Hello! Exactly the same problem after updating to 4.4.2, when connecting a client, the connection is reset. Waiting patch

Hi there. I updated the NetXMC server to the 4.4.1-1 version. I did the same with the NetXMC client in MacOS 13.5.2 However, when I tried to connect to the server appeared a pop-up window with the following message: An error has ocurred See the log file /eclipse/ 1694720730883.log I share the first three lines of this file: !SESSION 2023-09-14 14:45:30.531 ----------------------------------------------- eclipse.buildId=unknown java.version=16.0.1 java.vendor=Azul Systems, Inc. However, I installed this Java version in this computer. $ /usr/libexec/java_home -V Matching Java Virtual Machines (1): 17.0.8 (x86_64) "Oracle Corporation".... Any idea how can I fix this eclipse issue ? Thanks in advance

Hi, there. I have netxms-sever to 4.4.1-1 version installed. When I log into the server in no time appear the following pop-up window: Any idea how to fix this communication issue? Thanks in advance [image: connectionetxms2023.png]

Hi, Victor. First I appreciate your time to read my message. Second, I will follow your directions to try to fix this NetXMC client issue.

Hi, Filipp. Awesome ! Thanks.

Hi, gkaudewitz. First I appreciate your time to reply my follow-up message. Second, I am going to follow your comments. Thanks. My best Jose

Hi, Filipp. our new production NetXMS server is up and running. Thanks a lot to Victor and you for your kind help. Kudos. Finally, What I did to fix the connection error window in the latest post reply. I updated the NetXMS client. Problem solved. My best Jose

@jbriseno said in Telegram channel Issue: Hi, Filipp. First I appreciate a lot your time to help me to fix my Telegram channel issue. Second, today, I found the technical reason for that Telegram channel configuration change its status in unxpected way. Because, I added an event with the Telegram bot in the Actions Configuration menu. I updated it. Then my problem is solved. Finally, according with my participation in other Open Source Projects, NetXMS project offers to its members an excellent support. Kudos. Problem solved Thanks my best Jose I have this issue too. What did you change in the actions configuration to fix this?

Hi, Filipp. I got it. This Bug message appeared when I opened the Syslog parser window from the Configuration menu. I hope this helps. [image: syslogparser.png]

It's strange - there are no errors on either side, server reports normal connection closure: 2020.12.16 16:35:57.592 *D* [client.session.0  ] readSocket: connection closed Timestamps are also quite old and not in sync between server and client - do you have correct time on server and client? If yes, are those logs latest for version 3.7? Also, are they in same time zone? Best regards, Victor

Hey, there. When I upgraded to NetXMS server 3.7 from NetXMS 3.6 the computer screen sent the following message: Setting up netxms-agent:amd64 (3.7.116-1) ... Setting up netxms-server:amd64 (3.7.116-1) ... NetXMS Database Manager Version 3.7.116 Build 3.7-116-g133064d484 (UNICODE) Upgrading database... Database is locked If you want to upgrade netXMS server succesfully, please type: nxdbmgr unlock Then nxdbmgr upgrade Finally sudo systemctl start netxmsd P.S. It works well with Desktop Managment tool 3.6 so far. My best wishes Jose

Hi, Filipp. I got it. Thanks !

Did you open User Manager recently? From the same netxms console, or from another machine? If you open Tools-> Server console, what is the output of show sessions command there? Does this error stays, if you close netxms management console and start it again? Most probably it will go away if you restart netxms server process.

Most likely it is caused by bug we have fixed recently in development branch. Fix should be included into upcoming 3.7 release. Best regards, Victor

According this: https://www.netxms.org/forum/general-support/invalid-network-mask-4369/ and this: https://www.netxms.org/forum/general-support/invalid-network-mask/ The network mask on first device found in certain subnet is considered as correct one, but I didn't test it, I have these alarms disabled in my installation.

If tables are already created - run "nxdbmgr upgrade"

On startup netxms management console downloads netxms.mib file from server (or if it's already downloaded, checks, if it needs downloading again). As a workaround you can set "Connection over slow network" checkbox on console's login screen - it will omit mib file downloading. Or you can try to copy /var/lib/netxms/netxms.mib  file from server and putting it in ~/.nxmc/data folder, but I am not sure it that will work. How fast is your network connection from your desktop to NetXMS server? What are OSes on the server and your desktop? Is your netxms console the most recent version?

You can check the list of published packages in package repository, e.g. for Ubuntu Focal Fossa: https://packages.netxms.org/ubuntu/pool/focal/main/n/netxms/ Currently it's 3.6.300 Make sure you run apt update prior to apt upgrade
