I assume/guess it could be - previous sampling session was not stopped, but next sessionstarted. (You uses many CPU events, they willrun in multiple sessions.)
My recommendations are:
1.Restart machine to ensure that vtune driver is ready
2. Change Sample After Value (SAV) ofevents to large number, sample interval will be bigger - do it on "Sample Configure" dialog.
3. (Optional) Reduce/remove CPU events to be asingle session activity, create new activity for Others.

Hello Sir,
Thanks for your reply.
Can you please explain how to turn on verbose option of vtserver ?
Do I need to run "vtserver -v" command after vtl command or need to change any vtl command parameter ?

I think that you can use original options for vtserver or vtl command, just add "-v" option which will not impact on other options.
