I want to save the information displayed in the progess bar window (the popup) as the number of events processed, the total time, the initialization time, the rate, …

I tried to look here: … mance-tree
but the meaning of the branches are not very well documented, and I can’t find the simplest information.

I tried to use function like GetCpuTime after the proof session, but it returns 0.



The query info (including the results) are enveloped into a TQueryResult object which can be accessed via TProof::GetQueryResult(); e.g.

root [] proof->Process(dset, "myselector")
root [] proof->GetQueryResut()->GetUsedCPU()

should give you the CPU time used by master and workers.
I will check why proof->GetCPUTime() returns always 0.
