Function documentation

TPerfStats(TList* input, TList* output)

 Normal constructor.

~TPerfStats()

 Destructor

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.
 See WriteQueryLog for the descripition of the structure sent for monitoring
 when fMonitorPerPacket is kTRUE.

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 UnzipEvent(TObject* tree, Long64_t pos, Double_t start, Int_t complen, Int_t objlen)

 Record TTree file unzip event.
 start is the TimeStamp before unzip
 pos is where in the file the compressed buffer came from
 complen is the length of the compressed buffer
 objlen is the length of the de-compressed buffer

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()

 Send to the connected monitoring servers information related to this query.
 The information is of three types: 'summary', 'dataset' and 'files'.
 Actual 'table' formatting is done by the relevant sender, implementation of
 TProofMonSender, where the details are given.

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.

void SetMemValues()

 Record memory usage

void GetMemValues(Long_t& vmax, Long_t& rmax)

 Get memory usage

TPerfStats(TList* input, TList* output)

void SetNumEvents(Long64_t num)

{ fNumEvents = num; }

Long64_t GetNumEvents() const

{ return fNumEvents; }
