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 start)

 Open file event.

void FileReadEvent(TFile* file, Int_t len, Double_t start)

 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() const

 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 (
   id            INT NOT NULL PRIMARY KEY AUTO_INCREMENT,
   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()

{}

void SetNumEvents(Long64_t num)

{ fNumEvents = num; }

Long64_t GetNumEvents() const

{ return fNumEvents; }
