I would like to use the class TTreePerfStats for the jobs that run in the proof slaves.
I saw there was an similar thread opened by Ana, but I couldnt arrive to a conclusion
What Im trying to do is to create a TTreePerfStats object in the Init function
if (!tree) return; fChain = tree; m_ps = new TTreePerfStats("ioperf",fChain );
and in the SlaveTerminate I save it to a file locally, I didnt even try to added to fOutput. And when I do that
m_ps->SaveAs( "/home/proof/DiskPerf.root" );
I get a segmentation fault:
TCanvas::MakeDefCanvas: created default TCanvas with name c1

while running the same job in a local machine, out of proof, it works and I can see the file generated by the class TTreePerfStats.
Should the TTreePerfStats works within proof jobs? anyway to make it working?
