NAME
pprof - manual page for pprof (part of google-perftools)

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 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
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()
