EXAMPLES

91       pprof /bin/ls ls.prof
92
93              Outputs one line per procedure
94
95       pprof --gv /bin/ls ls.prof
96
97              Displays annotated call-graph via 'gv'

100
101              Restricts to code paths including a .*Mutex.* entry
102
103       pprof --gv --focus=Mutex --ignore=string /bin/ls ls.prof
104
105              Code paths including Mutex but not string
