Windows 32/64, RHEL 8

It has been moved into a standalone plugin.

On RHEL install zabbix-agent2-plugin-postgresql

On windows for now it's only available from sources https://cdn.zabbix.com/zabbix-agent2-plugins/sources/postgresql/zabbix-agent2-plugin-postgresql-1.2.0.tar.gz

Should i do anything else to link this plugin into agent? 

I installed zabbix-agent2-plugin-postgresql but it not listed at plugins after restart agent.

My log:

Should i do anything else to link this plugin into agent? 

Did you install from packages? There it must work out of box.

Or did you build from source? Then the plugin conf file must loaded by agent2.
Plugin comes with a *.conf file.

1. Inside you must specify the full path to the plugin binary.
2. Put the plugin conf file where agent2 is looking for includes (See agent2 conf file).

That should be it.

After updating to 6.0.10 (on Ubuntu), we're facing the same issues as described here and in ZBX-21894: PostgreSQL monitoring stopped working ("Unknown metric pgsql.*"). And on top, the all of a sudden "loadable plugin" is missing in the Ubuntu packages: It's not included in "zabbix-agent2" and there is no "zabbix-agent2-plugin-postgresql" package in the official Zabbix repo.

IMHO that change (previously built-in plugin becoming a "loadable" one - but not being shipped) was a bit too much of a breaking change for a patch version....

After updating to 6.0.10 (on Ubuntu), we're facing the same issues as described here
