Enterprise Library Test Guide
Area Performance counter name Threshold
Logical Disk (drive) % Idle Time This value should be higher
than 90 percent. Values lower
indicate that either there is
paging or the application block
writes to the SQL Server database.
This value should be
high for computers that host
Enterprise Library.
System Threads This value should be stable
and read in conjunction with
the Process\ThreadCount
performance counter.
System Context Switches/sec This is the rate of switches
from one thread to another.
The value should not be
higher than System\Threads
* 20. Higher values indicate
that there is either contention
or context switching from
kernel mode to user mode.
The ContextSwitchesPerSec
performance counter should
linearly increase as the
throughput, load, and the number
of CPUs increases. If it
increases exponentially, there
is a problem. For Enterprise
Library, this number should
be low in all test cases for all
application blocks.
.NET CLR Security % Time in RT Checks This value should be less than
7 percent. It is the percentage
of elapsed time spent performing
runtime code access
security checks since the last
sample.
.NET CLR Exceptions (w3wp) # Exceptions Thrown This value should be zero,
except for the Exception
Handling Application Block,
when it should be ignored.
This application block causes
exceptions that are recorded
in the performance monitor.
SqlServer:AccessMethods Full Scans/sec This value should be less than
3.
