Before I forget to ask, are passive discoveries possible through a proxy as well?

Yes, but you have to enable SNMP proxy in agent (by adding EnableSNMPProxy = yes to core section) and you must use zoning, with this agent set as zone proxy.

Hi,

try to check with lsof how many file descriptors actually open. It could be descriptor leak. Also, are you sure that your changes in open file limit actually reflected on nxagentd process? If it is being started with systemd you may need to make changes to unit file.

Hi,

there is open change request for that: https://track.radensolutions.com/issue/NX-1826. Hopefully will fix it soon.

Can you please provide agent log on debug level 7 (after initiating active discovery range scan)?

Hi,

latest agent versions do store syslog records and SNMP traps in local database (since version 3.4).

Hi,

this is a bug that cannot be solved easily. Object tool filtering for displaying in context menu is done on client side. If client application does not have access to templates it cannot check if node is in that template or not. This can be solved by sending filtering request to the server, but that will require round trip to server on each right click on object (possibly combined with some sort of caching and push notifications from server when template membership changes) - this can significantly slow down UI.
Alternative approach for such filtering could be by using custom attributes - you can use configuration poll hook to set custom attribute for each parent template and then in object tool check for those custom attributes.

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

Currently client does not have built-in terminal emulation to run interactive command line tools like putty inside GUI. It is quite complex task to implement (especially on Windows).

Looks like the following query fails silently:

ALTER TABLE event_log RENAME TO event_log_v35_2;

Which is very strange. You can try to run nxdbmgr upgrade with -t option, it will print all SQL statements being executed. This particular upgrade procedure is indeed TimescaleDB specific.

Скорее всего устройство просто отдает интерфейсы в таком виде. Попробуйте сделать SNMP walk на ветки .1.3.6.1.2.1.2.2.1 и .1.3.6.1.2.1.31.1.1.1 - какой будет вывод? Можно сделать командой nxsnmpwalk или в GUI открыть MIB explorer на ноде и сделать walk оттуда.

Most likely you have broken gcc installation or some packages are missing. Make sure that you have installed: binutils, make, gcc-c++, bison, flex, openssl-devel, expat-devel, libcurl-devel, sqlite-devel, pcre-devel. Usually you do not need to specify location for openssl, pcre, etc.

Looks like files from netxms-base package are missing - try to re-install it.

Best regards,
Victor

You don't need to re-install netxms-release-latest.deb if you already did that - just run

apt update
apt upgrade

Hi,

there is no standard path for downgrade (because of DB schema changes, rest is straight forward). Schema can be downgraded manually but it could be quite complex and time consuming process, depending on what versin you want to downgrade.
Regarding desktop connection issues, please try to upgrade to version 3.6.300. We probably have identified root cause and there are chances that those connectivity problems will be solved.

Best regards,
Victor
