Managing System Performance

Im configuring a Memory counter with System Monitor.
Sybex says the Memory>Available Mbytes should be less then 4mb or you should add more memory.
With that said- when I look at report view it states 1130 for the Available Mbytes WTF?
1MB =1K bytes so as long as I'm under 4000 I'm okay concerning memory.
If I'm reading this right or wrong someone please respond.

Don't tell co-workers your going for a Cert that they don't have. They may think your trying to take their job.

I have a feel that system monitor isn't really used in the field.
Whats you guys take on this?
basicly this along with a few other system monitors which we ran every month provided us a good overview of how the system was running and gave us the chance to forsee (if thats how u spell forsee... probably not lol) any problems that might occur EG: maybe the proccessor was starting to slow over the months so you could say... right in 2 months (going from what the KPI has indicated) you are going to need a new... HDD... processor etc...
pretty important if a company doesn't have a full time techy - which alot of smaller companys don't have
