activity result not found

[surabhighaisas]

I am using VTune command line interface.

When i use following command

vtl activity -c sampling -o "-ec en='BUS_TRANS_ANY.ALL_AGENTS'"

it says activity created successfully, however when i try "view" for the activity it says "no activity result was found". When I try "show all" it shows the activity names in the list.

Can you please tell me if I am missing some step. Why is no result associated with the activity i created?

Hi:

The command line you executed only instructs the analyzer to create the activity. In order to execute the activity, or collect the data, you must include the run parameter, as in:

C:\> vtl activity -c sampling -o "-ec en='BUS_TRANS_ANY.ALL_AGENTS'" run

Also, in the display of the 'vtl show' command, once results have been collected, you will see them listed under the activity. Right now, all that is being displayed is the activity. Here is an example with results:

C:\>vtl show

Thanks a lot for your reply. I am interested in finding the overall utilization of system Bus. I have the results for BUS_TRANS_ANY.ALL_AGENTS and CPU_CLK_UNHALTED.BUSwith me. These consist of multiple values per module running on the system.

Wouldaddition of the results per modulegive me correct "systemwide" values for BUS_TRANS_ANY.ALL_AGENTS andCPU_CLK_UNHALTED.BUS?

Is there any way to directly get system wide values for various events instead of per module?

All events are collected system-wide! You can display the system-wide results using the summary view:

Also, you can use the "Formatting Options" to make the output more parseable by scripts and create a CSV file that you can then import into a spreadsheet or something like that. Or, use awk and total up the values for each core.
