NAME

   google-pprof - manual page for google-pprof (part of gperftools)

SYNOPSIS

   google-pprof [options] <program> <profile>

DESCRIPTION

          Prints specified cpu- or heap-profile

OPTIONS

   --cum  Sort by cumulative data

   --base=<base>
          Subtract <base> from <profile> before display

   Reporting Granularity:
   --addresses
          Report at address level

   --lines
          Report at source line level

   --functions
          Report at function level [default]

   --files
          Report at source file level

   Output type:
   --text Generate text report [default]

   --gv   Generate Postscript and display

   --list=<regexp>
          Generate source listing of matching routines

   --disasm=<regexp>
          Generate disassembly of matching routines

   --dot  Generate DOT file to stdout

   --ps   Generate Postcript to stdout

   --pdf  Generate PDF to stdout

   --gif  Generate GIF to stdout

   Heap-Profile Options:
   --inuse_space
          Display in-use (mega)bytes [default]

   --inuse_objects
          Display in-use objects

   --alloc_space
          Display allocated (mega)bytes

   --alloc_objects
          Display allocated objects

   --show_bytes
          Display space in bytes

   --drop_negative
          Ignore negaive differences

   Call-graph Options:
   --nodecount=<n>
          Show at most so many nodes [default=80]

   --nodefraction=<f>
          Hide nodes below <f>*total [default=.005]

   --edgefraction=<f>
          Hide edges below <f>*total [default=.001]

   --focus=<regexp>
          Focus on nodes matching <regexp>

   --ignore=<regexp>
          Ignore nodes matching <regexp>

   --scale=<n>
          Set GV scaling [default=0]

EXAMPLES

   google-pprof /bin/ls ls.prof

          Outputs one line per procedure

   google-pprof --gv /bin/ls ls.prof

          Displays annotated call-graph via 'gv'

   google-pprof --gv --focus=Mutex /bin/ls ls.prof

          Restricts to code paths including a .*Mutex.* entry

   google-pprof --gv --focus=Mutex --ignore=string /bin/ls ls.prof

          Code paths including Mutex but not string

   google-pprof --list=getdir /bin/ls ls.prof

          Dissassembly (with per-line annotations) for getdir()

   google-pprof --disasm=getdir /bin/ls ls.prof

          Dissassembly (with per-PC annotations) for getdir()
