What tool do you use to monitor your servers?
I manage two Windows development servers which are part of a much bigger network. I would like to monitor these two servers, but I want to avoid any situation which could probe or map the entire network. Most other workstations and servers are managed by a dedicated team and mapping out the network would probably set off alarm bells. Not to mention, I'm only interested in these two servers.
As an example: Spiceworks wants to do a network scan on first run. I want to avoid that and just configure in the specific servers I need to monitor. What would be a good server monitoring package for this situation?
