Zabbix Agent2 install - why mongodb, postgresql plugins?

[stevene1900]

Hello, I am wondering about Zabbix agent2 dependencies - zabbix-agent2-plugin-mongodb, zabbix-agent2-plugin-postgresql.

Why are these plugins listed as dependencies? Are they used at all by Zabbix agent, if we are not monitoring mongodb and/or postgres?

Thing is, initially support for monitoring of PostgreSQL and MongoDB was built into Agent 2. Then, at some point, Zabbix decided to make Agent 2 as modular as possible, moving all the specific functionality to the modules. So, since Zabbix didn't want to break things for those that used this functionality it was decided to make the modules as dependencies. Think of it as, they are still build-in but not exactly. :-)

Seems useful for the initial transition, but at this point it seems like it could be dropped, or at least downgraded to "Suggests".
