actually, you should have gotten this error regardless of the agent's status. it's basically telling you that there's no point to ignoring a platform. since agent's have a one-to-one correspondence with platforms, this action would be analogous to starting an agent and then not wanting any of its results. although this is technically possible, we assume that the user clicked the wrong thing. so, we tell the user through the error message in the exception that they need to commit the platform first, and then they can ignore servers.

Hm. I started an agent on a machine and then decided I didn't want that machine to be monitored. By then the resource had been discovered. I wanted it to go away, so I clicked "ignore". I think that was a perfectly valid thing to do.

What was my alternative? To import it and then delete the resource? Seems a lot more intuitive to just "Ignore" it. Also, it seems like this button would be a simple way for admins to "ignore" machines where someone else installed an agent without permission. I know we have security features one can use to prevent that, but this is a 'simple' way.

Edit: Also, this error message is not helpful to the end user.

ok, jeff, you convinced me. this would be a simple way of getting around mistakes and whatnot. just gotta change the server-side ignore logic.
