Measurement
Unit |
Interpretation |
| Request_rate |
The rate of requests for ASP pages during the last measurement period
|
Reqs/Sec
|
|
| Transaction_rate |
The rate of transactions started per second
|
Trans/Sec
|
|
| Error_rate |
Rate of errors during ASP processing per second
|
Errors/Sec
|
|
| Data_rcvd_rate |
The rate of data being received by the web
server for ASP processing
|
Kbytes/Sec
|
|
| Data_xmit_rate |
The rate of data being transmitted by the web
server in response to ASP requests during the last measurement period
|
Kbytes/Sec
|
|
| Execution_time |
The execution time of the last request in seconds. To
determine where the bottleneck is, compare the execution time with the wait time.
|
Secs
|
If the wait time is low, but
execution time is high, this indicates that
the application logic in the ASP pages could be causing the high execution
time. On the other hand, if wait time is high
and execution time is low, this indicates a server-side bottleneck (e.g.,
due to too few processing threads).
|
| Wait_time |
The amount of time that the last request had to wait for
service
|
Secs
|
During ideal operation, the wait
time should be near 0. If this value is high, it indicates that many
requests are being queued for ASP processing.
|
| Current_executions |
The number of requests being currently executed
by the ASP engine.
|
Number
|
|
| Current_queue_length |
The number of requests that are currently
waiting for service
|
Number
|
Ideally, this metric should be 0. A consistent non-zero
value is an indicator of a server-side processing bottleneck.
|
| Failed_requests |
The number of requests that failed during the last
measurement period. This includes
authorization failures and rejections.
|
Number
|
|
| Rejected_requests |
The number of requests that were rejected during the last measurement period
|
Number
|
|
| Pending_transactions |
The number of transactions awaiting processing during the last measurement period
|
Number
|
|
| Transaction_commits |
The number of transactions that were committed during the last measurement period
|
Number
|
|
| Transaction_aborts |
The number of transactions that were aborted during the last measurement period
|
Number
|
A very high value of this measure could indicate a server-processing bottleneck.
