reported the following error:

an error occurred during sampling

Can you please give some suggestion for this error ?

Thanking you,

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.

Another recommendation would be to turn on the verbose option of the remote agent (vtserver) and see if the additional information provides any insight into the problem. See output of "vtserver -h".

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 ?

Thanking you,

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

Hello Sir,

Its strange I found -v option on man page of vtl command but when I tried failed saying unknown option.
