Yup - the SSH monitoring runs small programs you install on the remote PC. They have mostly fallen by the wayside as most people prefer SNMP + command based monitoring vs an agent (if they wanted an agent I guess they'd just use a monitoring tool that uses agents).

You could write your own performance collectors to do "everything" (well, whatever you wanted to write) using commands or whatever makes sense. You can use Zenpacks on the zenoss server to extend it if any do what you want.

It's not horribly difficult to write command datasources, but it's not easy either IME. It definitely takes some time to understand Zenoss and how to get everything working. Oh - you can look for Nagios plugins, that's basically what Zenoss command datasources *are*. If one already exists, that's half the battle, and you just need to do the graphing/alerting integration in Zenoss.

I'm not sure that any of this helps...

Uh-oh, I think I have a conceptual problem here...

So, "Zenoss-Plugins" is a Python package that must be installed on the _remote_ 
system, not a package for the monitoring computer?

This also seems to imply that some of the collectors just use standard shell 
commands and so they don't need the plugins? Is that why I'm getting some data 
now?

And that leads to the question of why have a requirement for installing 
programs on the remote system at all?

Why are these called "plugins", then? What do they plug into? They appear to be 
independent programs that ZenOSS calls via SSH?
