Currently there is no out of the box functionality for that. It would be nice to have, but it depends of available development resources. And the other question is how this should be implemented. Should we compare the actual value with average for, say an hour? Or with average value one day ago? Or with average on the same day of week or last business day? First of all, you can try mean deviation threshold, it probably should increase if the value drops significantly. Number of samples in this case is the time during which the mean deviation is calculated. You need to experiment on this. The other approach is to have two DCIs. First is collecting data as usual. Second is scheduled, e.g. every 10 minutes (it should not be too frequent to avoid producing load on the system), calculates average value of the first DCI for a period of time and stores it. First DCI then has script threshold that compares actual value with the average value. This script threshold can be quite advanced - compare value 24h ago, etc... Please give an update how you implement this for you.

Looks strange. Could you please provide screenshots of DCI configuration and values history? Best regards, Victor

Hi, you can use DBQuery subagent for it: https://www.netxms.org/documentation/adminguide/application-monitoring.html?highlight=dbquery#application-database-monitoring Best regards, Victor

I would rather execute such nxshell script as an action for SYS_NODE_ADDED events - that way it will run only once when switch is added, because normally you don't need it to run on schedule. Best regards, Victor

Hi! Let me comment the steps that you've performed. Part starting from tar zxvf netxms-3.5.90.tar.gz You did compilation from sources here. For Ubuntu it's actually not needed, since we provide packages (which allow to install/upgrade software via apt-get) Part starting from wget http://packages.netxms.org/netxms-release-latest.deb If you look in the documentation, there are two sections there - "Using netxms-release package" and "Manually". Only one of these was meant to be performed and the recommended is first one. You can delete the last line in /etc/apt/sources.list.d/netxms.list that was added by steps from "Manually" section, but it's probably not causing problems (at least, for now). Now, the reason for the error: Your database has format version 35.15, but server is compiled for version 34.16 When you did installation from sources, you used netxms-3.5.90.tar.gz., so it's version 3.5.90. And you did /usr/local/bin/nxdbmgr init there, so the database was initialized for that version. But when you did install from packages, you got previous netxms version, because 3.5.90 was not available in packages yet (it was just released on that day and the packages were still prepared). As of today, you can do apt-get update apt-get upgrade and you should get 3.5.90 from packages. You can check package versions by running dpkg -l | grep netxms When you have 3.5.90, chances are that netxms will just start. But I am not sure about that, since you had /usr/local/bin/nxdbmgr: error while loading shared libraries: libnxdbmgr.so.35: cannot open shared object file: No such file or directory error when initializing the database. So it's recommended that you delete your netxms database, recreate it and initialize it: echo "DROP DATABASE netxms;" | mysql -u root -p echo "CREATE DATABASE netxms;" | mysql -u root -p echo "GRANT ALL on netxms.*to 'netxms'@'localhost' IDENTIFIED BY 'PaSsWd';" | mysql -˓→u root -p in netxmsd.conf you have some old way of specifying database driver, please specify this way (a proper file example usually installs when installing package, but you already had this file, so it was not overwritten): DBDriver=mysql.ddr Then initialize the database - you also had old way of doing this, currently you should do just: nxdbmgr init

Dear Kirhenshtein, This is the reason why I have not seen the MIB tree, Thank you for your time and consideration. Best regards

Hello Alex, thank you so much, with netxms-dbdrv-mariadb it's work like a charm! Have a nice day

I first tried updating my Server to 3.5.90 and, clicking through all the switches, i didn't find a single one with empty interfaces tab. So this seems to be fixed, thanks for the update and for the really great software in general! Frank

32bit builds are not supported by the framework we use (Eclipse RCP), so it's not possible for the moment. You can install Web interface instead (on any 64bit capable system) and access it from 32bit system with the web browser.

Hi! There is an option called tunnel, when agents are establishing connection to NetXMS server. Connections are performed to port 4703 (configurable in server configuration parameters), so you need to open this port on the router where your server is running. Configuration is a bit tricky - you need to create security certificates, just follow the sequence in the documentation: https://www.netxms.org/documentation/adminguide/server-management.html?highlight=tunnel#server-configuration-for-agent-to-server-connection-tunnel-connection

It works great, thank you!

Should be available now

Memory leak has been fixed. It will be included in next release. It should be possible to run without administrative rights. Communication of user support application happens through main agent process. So it's necessary to start agent process as well. This could be done by some sort of bat file, so you can try packing all this into self extracting archive or something. Current issue will be that agent process will produce a console window while it's running. It could be possible to add hiding of it's window is some of future releases. You can try experimenting with all this - may be there will be some other issues on that way.

Hi! It worked like a charm, thanks!

Hi, is it possible to organize SNMP access for us to few TPLink devices so we can test how server see them and fix any discovered issues? Best regards, Victor

Hi,, The problem was due to a library conflict... https://www.netxms.org/forum/general-support/nxdbmgr-init-segmentation-fault/msg28226/ all is ok now. Thank you for your help. BB

This is how the integration was designed - currently it's not possible to close alarm while helpdesk ticket is open.

If I understand you correctly, you are trying to use a Table DCI and fill it in with data. Did you consider using summary tables - it's a way to show a DCI from multiple nodes in table format. https://www.netxms.org/documentation/adminguide/visualisation.html#summary-table

It's a known bug - https://track.radensolutions.com/issue/NX-1897. Fixed in 3.4.284. Best regards, Victor

Hi, we've fixed it in version 3.4.313. Windows installer and source package are already available for download and deb repository will be updated soon. Best regards, Victor
