This counter shows the percentage of pages in the buffer pool without needing to read from disk. Thresholds are
expressed as a percentage of hits; instances in which the requested page was found in the cache.

This counter is typically a good indicator of whether there is sufficient RAM installed in the server.
If you are using SQL Server Standard Edition in a large enterprise or hosted environment and this counter (as
well as other performance counters) is not within the recommended range, upgrading SQL Server to Enterprise
Edition may be the next step. Upgrading SQL Server to Enterprise Edition requires an upgrade of the operating
system to Windows Server 2008 R2 Enterprise Edition.

Platform Diagnostic Counters
– Automatic Collection
The following counters values are sampled and collected automatically (by the Node Manager):
Counter values are stored in a disk file on the server.
Counter values are sampled at a “one minute” interval.
Data files contain a rolling window of counter values – older data is discarded in lieu of new
data. Data is stored in multiple files (maximum size is 1 MB each) and a maximum of 45
days of data is saved.

Percentage (0 – 100%)
% Processor Time is the percentage of elapsed time that the processor spends to execute a non-Idle thread. It is
calculated by measuring the duration of the idle thread is active in the sample interval, and subtracting that time
from interval duration. (Each processor has an idle thread that consumes cycles when no other threads are ready
to run.) This counter is the primary indicator of processor activity, and displays the average percentage of busy
time observed during the sample interval. It is calculated by monitoring the time that the service is inactive and
subtracting that value from 100%.
