Yes, Postgres should be installed prior to installing NetXMS. https://www.enterprisedb.com/downloads/postgres-postgresql-downloads
During installation of Posgres you will enter password for super user named "postgres". When installing NetXMS, use DBA login name "postgres" and the password that you entered.

Login name, database name and password could be anything - the installed will create postgres uses with that login name and password and will create a database. These credential will be written to NetXMS server configuration file (netxmsd.conf), so when it starts, it will use this information to communication to the database.

Watchdog process is checking if all threads are running by communicating with them. There is some timeout, if watchdog does not receive reply within that timeout, these events are generated. In this case after 15 milliseconds after the error was generated watchdog received reply from the thread which resolved the error.
This could be if there's high CPU and/or RAM usage on the system. Check monitoring data on CPU and RAM consumption on your server.

В планах есть мысли сделать NXSL функции для конвертации текста в разных кодировках.

На линуксах это определяется CodePage в конфигурационном файле сервера.

What database are you using? What's the contents of netxmsd.conf? Did you install or upgrade?

Try installing mysql-libs package.

Also, it could be easier to use Debian or Ubuntu, as we provide packages for these systems.

Looks that without zoning only agent running on netxms server is user for web service queries.
So you need to enable zoning, create a zone, configure that agent that has permissions as proxy for that zone and put the node that has the DCIs to that zone.

You can make add an Agent configuration policy to a template and apply that template to these nodes. Agent merges lines in it's configuration file with lines coming in configuration policy.

It all depends on the user under which netxmsd process is running. You can see that by issuing
ps aux | grep netxmsd

If netxms is installed from packages on Debian, it install systemd startup script and from there it runs under root.

Was netxms compiled? Try adding --with-mysql to ./configure command. There's also ./configure --help that might be helpful.

Yes, it's so for some historical reasons. Will stay so in 3.x versions, but hopefully will be reworked in 4.0

You can use the desktop app on any machine, not necessarily it should run on the server. It just connects to the server on TCP port 4701.

Try using desktop console. It might work much faster with maps.
There also is an option to export map to image in desktop console.

Имя лог файла задается в конфиге сервера - netxmsd.conf. Под линуксом это обычно /var/log/netxmsd

В клиенте зайти в Tools -> Server Console. Там дать команду
debug 6
сервер перейдет на 6 уровень отладки. В лог при этом будет сыпаться очень много строк.
Выполнить опрос и дать команду на уменьшения уровня отладки
debug 0

Еще там есть команда logmark, она добавляет в лог "******* MARK *******". По этим отметкам удобнее искать, какая часть лог файла нужна.

Are you using desktop console or web console?
