Я бы попробовал сделать Poll -> Configuration (full), если не поможет, то просто удалить эту ноду и создать заново (или подождать, нода сервера должна пересоздасться сама)

Test from template is actually not yet implemented, that's why the error. Apart from that your DCI should work, whether defined directly on a node, or in a template.

This message means that nxmc is older then the server.
What distribution did you use before? Was it for Windows?
Currently you can just download nxmc separately from https://www.netxms.org/download/

Тут поможет дебаг на 9 уровне. В принципе он нужен только по тегу db.query, но сейчас драйвер базы данных сделан так, что он включает нужно логирование только если глобальный дебаг при старте равен 9.
Можно сделать так - указать DebugLevel = 9 в конфиге сервера и сразу после запуска выполнить
nxadm -c "debug 0"
nxadm -c "debug db.query 9"

В логе перед строчкой SQL query failed должны будут быть строки с расшифровкой полей SQL запроса, по ним можно будет определить с какой нодой это связано.

rpm пакеты есть в планах, но точный срок назвать сложно.

Both Postgres and TimescaleDB are in one driver - Postgres. When performing nxdbmgr init it asks what type of database to use.

SSH connections are performed from netxms agent. It is either a proxy, or agent on netxms server. These agents need to have ssh subagent loaded (SubAgent=ssh.nsm in config file).

NetXMS takes CPU load information from /proc/stat. We just read this file once per second, calculate deltas and divide the deltas by sum of them.
Please run below command on a container that got into that state and share the output:

n=1; while [ $n -le 60 ]; do cat /proc/stat | grep cpu0; sleep 1; n=$((n+1)); done

Then restart the container and get these stats again so we could have some data for comparison.

Looks interesting. Does it happens for all LXC containers on Proxmox or only for some of them? What is Proxmox version and what are the systems that are insde the containers?

Do you have particular reasons to compile the agent? There are packages for Ubuntu: https://www.netxms.org/documentation/adminguide/installation.html#installing-on-debian-or-ubuntu

There's a field called Format string that accepts java8 format strings. And there's a custom thing - if there's * character after %, multiplier operation is done first and then format is applied.
So:
%*.2f will be the value with multiplier, having 2 signs after decimal

And the same input value can be even used twice:
%*1$.2f (%1$d b)

What kind of interface table do you mean? Is it a metric of netxms agent or from some SNMP device, or your custom external table? Can you show how data in that table look like?
What result do you want to get?

Most probably another copy of netxmsd is running. You can check what process has acclaimed a port with
sudo netstat -lptun
You may need to install it.
sudo apt install nettools

These are ports 4701, 4703 and 4747.

Developers are planning to rewrite the part of code that is responsible for that bug. So it makes no sense to debug the current code as it is, let's wait for a new version.

Ah, right, you have server on Windows. For Win it too complicated to set up the compiling environment. Let's get back to this next week, we will try to make a test build that should be able to get some more debug information.
