Newbie questions

I have just gotten started. And have a couple of questions (for now)

1. I have deployed agents to a little over 40 Windows hosts. The "required server performance" number has jumped from a little over 1 to about 55. Is there a value above which I should be really concerned? I did read the manual, which stated it is the expected number of values processed per second but there wasn't much guidance on what to do with this number. I'm guessing it is displayed prominently on the Dashboard for a reason. Any insights would be appreciated.

2. I used the "Template OS Windows" template only on the hosts. I have a few reports that some nodes have "Disk Space on C is less than 20%". However, when looking at that template, I don't see any triggers that would indicate this warning. Sorry if this is a totally stupid newbie question, but where did this come from? Where is this trigger defined? (not that I am complaining about it - I just want to understand it so that I can create/develop my own custom template)

1: Is just an indication, it really doesn't say a lot. I just shows you how much data per seconde is pushed to the server. There is no rule on what the limit is, it all depends on your environment.

2: The trigger is defined in the Discovery rule of the windows template (Template OS Windows - Discovery Rules -> Mounted filesystem discovery -> Trigger prototypes)
It's in there because the trigger depends on the item discovery.

The higher the number, the more performance you'll likely need. It's nothing much to be concerned about, but if you start having performance issues you can use it as an indication.
