 \Memory\Available Mbytes Available – MBytes measures the amount of physical memory available to processes running on the computer, as a percentage of physical memory installed on the computer. The following guidelines when measuring the value of this performance monitor counter: 50% of free memory available or more  = Healthy 25% of free memory available =  Monitor 10% of free memory available =  Warning Less than 5% of free memory available  = Critical, performance will be adversely affected \Memory\Pages/sec This performance  – monitor counter measures the rate at which pages are read from or written to disk to resolve hard page faults. To resolve hard page faults, the operating system must swap the contents of memory to disk, which negatively impacts performance. A high number of pages per second in correlation with low available physical memory may indicate a lack of physical memory. The following guidelines apply when measuring the value of this performance monitor counter: Less than 500 = Healthy  500 - 1000 = Monitor or Caution   Greater than 1000 = Critical, performance will be adversely affected Measure available memory on the guest operating system Memory that is available to – the guest operating systems can be measured with the same performance monitor counters
