Process type (child or parent), status of the process (Starting, Reading, Sending, Waiting, etc.), and how long the current request has been being processed (or how long the previous request was processed for, if the process is inactive at the moment the report was made).
How many bytes have been transferred so far, and how many requests have been served per child and per slot. (When the child process quits, it is replaced by a new process running in the same slot.)
CPU times used by the process: total, utime, stime, cutime, cstime.
For all processes (mod_perl and non-mod_perl), the following information is reported:
General process information: UID, GID, state, TTY, and command-line arguments
Memory usage: size, share, VSize, and RSS
Memory segments usage: text, shared lib, date, and stack
Memory maps: start-end, offset, device_major:device_minor, inode, perm, and library path
Sizes of loaded libraries
Just as with the multi-process mode, this mode allows you to automatically refresh the page at the desired intervals.
