Agent Plugin's what do they do?

Question

I have been deploying the Agent with success, but can not find any information on what each plugin does and some seem redundant. Thanks for any details.

Hello,

Agent plugins more or less mirror product structure on pollers. JobEngine is job execution plugin, similar to JobEngine service on pollers. If this fails to install nothing is polled. Other plugins cover parts of whole product polling in the same way you have it when polling agent-less. Two interfaces plugins are just internal separation that SAM uses.

You don't have any way how to choose what plugins are installed and what not, agent always gets all that are needed for full polling support. As long as they are green you are good. If some failed (usually just JobEngine can fail) you should have option to reinstall the plugin from UI. It may also fails due to some dependency failure - JobEngine needs Visual C++ Redistributable package and if that fails to be installed for any reason JobEngine also fails. You should see some hint in the error message in such case so you may try to install VC++ package manually if automatic installation fails.
