I thought this could be the reason. Thanks Tomas.

It seems that cached db is getting corrupted, stop remove of the /usr/local/var/lib/netxms/nxagent.db start Is solving the issue. Thanks for guiding me.

Yes, simply create a dashboard and put all the graphs you want on it

I got it working. One thing that kept tripping me up is that when I would make a change to the discovery script and then Force DCI poll, it would say that it was unsupported. So I would make more changes and that would be unsupported. I probably had it working earlier and just needed to be patient for NetXMS to do it's thing. I had to still see if it was Windows 2003 because newer versions use both services but only the MpsSvc is the firewall. [image: Capture.JPG]

Hi, actually it is supposed not to replace existing events but get first available ID during import. Looks like corrupted database or some other bug. Please keep an eye on event definitions and let us know if something similar happens again. Best regards, Victor

Also if you dont require advanced ICMP statistics (provided by Ping Subagent) a simple "Internal" type DCI "PingTime" will allow you to collect and graph ping response time.

Problem with geo maps in web UI is that they actually downloaded by application server, not by client browser. You can set HTTP proxy settings for application server's JVM (for example, by adding -Dhttp.proxyHost=host -Dhttp.proxyPort=port to JVM command line in application server startup script).

You can add any DCI value to map link. Right click on map link, go to properties, and add DCIs to show on "data sources" page. Best regards, Victor

I suppose currently it's not possible with tables - you need something like "diff" for table row but table thresholds operates only on current table value. You can try to use instance discovery - it will create DCI for each OID, and then you can use diff threshold to detect individual OID value change. Best regards, Victor

Hi Victor, Thank you very much for your support. I am waiting for the new release. BR, Zsolt

Hi, usually there is $object global variable when relevant. Best regards, Victor

apt-get install netxms-agent apt-get install netxms-server apt-get install netxms-dbdrv-mysql I recommend checking out the video tutorials if you are new to NetXMS https://www.netxms.org/forum/general-support/netxms-video-tutorial-series/

I found that with quite a few performance counters (even some that do not say they are "averages"), I still have to configure the "Sample count" in the DCI to 2 to make them return useful data. Maybe it's the same in your case?

Ok, I solved it by script: sub main() { val1 = GetDCIValueByDescription($node, "Used physical memory"); val2 = GetDCIValueByDescription($node, "Physical memory used for buffers"); val3 = GetDCIValueByDescription($node, "Physical memory used for cache"); return val1 - val2 - val3; }

Thanks Victor, will make a note

Hi, Our NetXMS v2.0.2 server on Windows 2008 R2 stopped working today and kept crashing on startup. The event log showed [ERROR] EXCEPTION 0xC0000005 (Access violation) at 0x00659F20 (crash dump was generated); From the crash dump I found it was caused by nxcore!ScheduledMaintenance+0x150, which appears to have something to do with nodes that have been set to maintenance mode. I checked the database and found that there were some entries in the scheduled_tasks table pointing to IDs of nodes that have been deleted meanwhile. Unfortunately, running "nxdbmgr check" did not clean these up, so I deleted them manually and the problem was gone. Not sure if this is something already solved in a later version or not, but thought I'd let everyone know in any case!

Only to map, I will try to add also devices. Will let you know, thanks Edit: Yes, that was the problem. Thank you.

It the code I found that this may happen when it's not possible to run "stat" on this folder. But there is not printed why it was not possible(I can add this to code, but no idea about next release date). One of possible problems can be that user that runs NetXMS does not have access to this folder.

Hi, you need C++ compiler to build NetXMS agent. Try to install one. Best regards, Victor

Just as an addition, its also fully documented in the Administrator Guide here: https://www.netxms.org/documentation/adminguide/agent-management.html#agent-external-parameter
