httpdstat.d

httpdstat.d(1m) 						   USER COMMANDS						   httpdstat.d(1m)

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.

IDEA

       Ryan Matteson (who first wrote a solution to this).

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       httpdstat.d will run until Ctrl-C is hit.
