Verifying response from agents

[Dwayne Skinner]

I've had several incidences where servers in SIM looked like they were working properly but really weren't. For example, I've had servers showing green when in truth they weren't responding at all. I've had servers that do the contract and warranty but don't put an alert up when a harddrive goes bad.

How do I know that my servers are responding in SIM?

I have over 200 servers and I'm hoping there is a method I can use to test response thats automated so that I won't have to go to each server physically and test.
