NAME

       httpdstat.d - realtime httpd statistics. Uses DTrace.

SYNOPSIS

       httpdstat.d [interval [count]]

DESCRIPTION

       This prints connection statistics for "httpd" processes, such as those from an Apache web server.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       Print statistics every second,
	      # httpdstat.d

       Print every 5 seconds, 6 times,
	      # httpdstat.d 5 6

FIELDS

       TIME   time, string

       NUM    number of connections

       GET    number of GETs

       POST   number of POSTs

       HEAD   number of HEADs

       TRACE  number of TRACEs

NOTES

       All statistics are printed as a value per interval.

       This version does not process subsequent operations on keepalives.

NAME

       newproc.d - snoop new processes. Uses DTrace.

SYNOPSIS

       newproc.d

DESCRIPTION

       newproc.d is a DTrace OneLiner to snoop new processes as they are run.  The argument listing is printed.

       This is useful to identify short lived processes that are usually difficult to spot using traditional tools.

       Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.

       Since this uses DTrace, only users with root privileges can run this command.

       This prints new processes until Ctrl-C is hit.
	      # newproc.d
