I had a look at mod_status and noticed that it already has a nice
extension hook. I extended peruser to register this hook and to dump its
child_info table when the status is requested. Please find the patch
attached to this email. You should compile and enable mod_status as
usual (don't forget to set ExtendedStatus to "on"). If you call your
/server-status handler as usual you should notice a new section at the
end of the output which will look like this:
> ID PID STATUS TYPE UID GID CHROOT INPUT OUTPUT
> SOCK_FD TOTAL P MAX P IDLE P MIN FREE PROCESSORS
> 0 30450 ACTIVE MULTIPLEXER 65534 65534 (null) 11 12
> -1 1 10 1 2
> 1 30451 ACTIVE PROCESSOR 1002 407 (null) 13 14
> -1 4 20 3 4
> 2 30455 ACTIVE PROCESSOR 1003 408 (null) 17 18
> -1 4 20 4 4
> 3 30452 ACTIVE WORKER 1002 407 (null) 13 14
> -1 4 20 3 4
> 4 30453 ACTIVE WORKER 1002 407 (null) 13 14
> -1 4 20 3 4
> 5 30454 ACTIVE WORKER 1002 407 (null) 13 14
> -1 4 20 3 4
> 6 30456 ACTIVE WORKER 1003 408 (null) 17 18
> -1 4 20 4 4
> 7 30457 ACTIVE WORKER 1003 408 (null) 17 18
> -1 4 20 4 4
> 8 30458 ACTIVE WORKER 1003 408 (null) 17 18
> -1 4 20 4 4
I hope that people will find this useful in monitoring/debugging peruser.
Janno: Can you try to figure out what's going on using this patch? The
stuff in your last emails was pretty hard to analyze because of all the
word wrapping. If you cannot teach your email client to leave the lines
intact then an attachment/url might be the better choice.
Sean: It looks like a lot of nice patches and fixes are floating around
right now. Can you please try to wrap them up in a new release? At the
moment everybody seems to have different patches applied which makes
sorting out stuff really ugly. Call it "beta" or something like that if
you feel that it is not stable enough for a release.
