• .NET threads trend graph—Shows changes of the number of .NET threads (including physical
threads and logical threads) running on the .NET server over the selected time period in a line

Physical Threads—Number of native OS threads created and managed by the .NET server to

Logical Threads—Number of current .NET thread objects created and managed by the .NET
server in the last polling interval.
Total Connections—Total number of failure attempts made by the threads in the Common

Set Threshold icon —Click the Set Threshold icon to set alarm thresholds for the

the level-1 threshold, and is highlighted in red when it reaches the level-2 threshold. You can
use either the global thresholds or user-defined thresholds.
History icon —Click the History icon for a monitor index to view trend statistics of the
physical threads, logical threads, total connections, or thread queue length in a line graph. By
