+/*
+ Origin: marian.ivanov@cern.ch
+ Make sys watch default plots (see $ALICE_ROOT/STEER/AliSysInfo.cxx):
+ Input - syswatch.log - text log file created by process to be monitored
+ Output - syswatch.root - root files with default histograms
+ Number of top violators - only top consumer displayed
+
+ Default histogram:
+
+ TOP violateors - CPU and Virtual memory usage
+ Detector reports - CPU and Virtual memory usage per detector
+
+
+
+
+
+ Usage example:
+ .x ~/rootlogon.C
+ gROOT->LoadMacro("$ALICE_ROOT/macros/PlotSys.C+");
+ MakePlots("syswatch.log","syswatch.root",10);
+ TFile f("syswatch.root");
