Windows PerfMon has many counters. A selection is suggested on http://technet.microsoft.com/en-us/library/cc782186(WS.10).aspx but that's still a lot.
Which counters would you suggest as being the most useful to quickly see if a remote machine has some problems? Also to which scale would you set them?
Please not that I'm interested in machine-wide issues, not just issues related to ASP, Windows Service or any other specific kind. Only general info for a Windows server.
I only wish to know if the machine is working fine or if something fishy is going on. Kind of a green, orange, red light. If the counter can help identify the origin, then better but not a must. PerfMon settings tips are welcome.
