NAME

       pprof - manual page for pprof (part of gperftools)


SYNOPSIS

       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 Postscript 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

       pprof /bin/ls ls.prof

              Outputs one line per procedure

       pprof --gv /bin/ls ls.prof

              Displays annotated call-graph via 'gv'

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

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

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

              Code paths including Mutex but not string

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

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

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

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