httpdstat.d - realtime httpd statistics. Uses DTrace. httpdstat.d [interval [count]] This prints connection statistics for "httpd" processes, such as those from an Apache web server. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the syscall provider.

Print statistics every second, # httpdstat.d

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

TIME time, string

NUM number of connections

GET number of GETs

POST number of POSTs

HEAD number of HEADs

TRACE number of TRACEs

All statistics are printed as a value per interval. This version does not process subsequent operations on keepalives.

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output. httpdstat.d will run until Ctrl-C is hit. Brendan Gregg [Sydney, Australia] dtrace(1M)
