Markus Frank wrote a tool that allows tracing all accesses to the transient event store:
The package is
Online/TESTracer and can be found in svn at:
svn+ssh://svn.cern.ch/reps/lhcb/OnlineExtra/trunk/Online/TESTracer
The package should be built in order to produce the library:
libTESTracer.so
The library should be preloaded to make override symbols from Gaudi:
setenv LD_PRELOAD ~/cmtuser/Brunel_v44r5/TESTracer/x86_64-slc6-gcc46-opt/libTESTracer.so
And the option file must be modified to add the new Auditor:
AuditorSvc().Auditors.append("TES::TraceAuditor")
See the example in
cmt/testROOT.py
