Function documentation

TPerfStats(TList* input, TList* output)
 Normal constructor.
void SimpleEvent(TVirtualPerfStats::EEventType type)
 Simple event.
void PacketEvent(const char* slave, const char* slavename, const char* filename, Long64_t eventsprocessed, Double_t latency, Double_t proctime, Double_t cputime, Long64_t bytesRead)
 Packet event.
void FileEvent(const char* slave, const char* slavename, const char* nodename, const char* filename, Bool_t isStart)
 File event.
void FileOpenEvent(TFile* file, const char* filename, Double_t proctime)
 Open file event.
void FileReadEvent(TFile* file, Int_t len, Double_t proctime)
 Read file event.
void RateEvent(Double_t proctime, Double_t deltatime, Long64_t eventsprocessed, Long64_t bytesRead)
 Rate event.
void SetBytesRead(Long64_t num)
 Set number of bytes read.
Long64_t GetBytesRead()
 Get number of bytes read.
void WriteQueryLog()
 Connect to SQL server and register query log used for quotas.
 The proofquerylog table has the format:
 CREATE TABLE proofquerylog (
   user          VARCHAR(32) NOT NULL,
   group         VARCHAR(32),
   begin         DATETIME,
   end           DATETIME,
   walltime      INT,
   cputime       FLOAT,
   bytesread     BIGINT,
   events        BIGINT,
   workers       INT
 The same info is send to Monalisa (or other monitoring systems) in the
 form of a list of name,value pairs.
void Setup(TList* input)
 Setup the PROOF input list with requested statistics and tracing options.
void Start(TList* input, TList* output)
 Initialize PROOF statistics run.
void Stop()
 Terminate the PROOF statistics run.
TPerfStats(TList* input, TList* output)
virtual ~TPerfStats()
