NAME

       forkstat - a tool to show process fork/exec/exit activity

SYNOPSIS

       forkstat [-d] [-D] [-e] [-h] [-s] [-S] [-q]

DESCRIPTION

       Forkstat  is a program that logs process fork(), exec(), exit(), coredump and process name
       change activity.  It is useful for monitoring system behaviour and  to  track  down  rogue
       processes that are spawning off processes and potentially abusing the system.

       Note  that  forkstat  uses the Linux netlink connector to gather process activity and this
       may miss events if the system  is  overly  busy.  Netlink  connector  also  requires  root
       privilege.

       Forkstat will display several columns of process related information:

       Title      Description
       Time       When the fork/exec/exit event occurred.
       Event      Type of event.
       PID        Process or thread ID.
       Info       Parent or child if a fork, or exit value.
       Duration   On exit, the duration the command ran for in seconds.
       Process    The process name. The name will be in [ ] brackets if it is a kernel thread.

OPTIONS

       forkstat options are as follow:

       -d     strip off the directory path from the process name.

       -D seconds
              specify duration in seconds to run forkstat.

       -e     specify  events  to  trace as a comma seperated list. By default the fork, exec and
              exit events are traced. Available events are:

              Event   Description
              fork    forks
              exec    execs
              exit    exits
              core    core dumps
              comm    process name changes in comm field
              clone   clone (normally on thread creation)
              all     all the events above

       -h     show brief help summary.

       -s     show short process name information.

       -S     show event statistics.

       -q     run quietly and enable the -S option.

EXAMPLES

       Show process activity with short process names and directory base path stripped off:
               forkstat -s -d

       Trace forks and core dumps only:
               forkstat -e fork,core

       Trace all events and print statistics at end:
               forkstat -e all -S

       Trace all events for 10 minutes:
               forkstat -e all -D 600

       Trace clones for 1 minute:
               forkstat -e clone -D 60
