On a running linux system.
how to find out Active StartServers (running as of now), number of active child processes and idle workers using oS commands or any other tools ?
Appreciate your help!!
apache2ctl status
And
apache2ctl fullstatus
Or apachectl depending on your setup.
See http://httpd.apache.org/docs/2.2/programs/apachectl.html You need to have mod_status enabled.
