Access apache log variables, eg %h in PerlLogHandler

[Brad <br...@intradonline.com>]

Is there any way I can read variables from apache's log system back into
a PerlLogHandler?  %h %l etc

mod_perl generally uses $r->bytes_sent() for this kind of thing

http://perl.apache.org/docs/2.0/api/Apache2/RequestRec.html#C_bytes_sent_

but note the caveat in the docs - it's unlikely bytes_sent() will match
mod_logio's results.  it's a shame mod_logio doesn't set its result in
subprocess_env, which would make accessing it's results a simple matter.

the cool thing, though, is that mod_logio itself has an api, registering
optional functions that you can call.  is, if you _really_ wanted
mod_logio's results you could use some simple xs to create a wrapper and
get at them :)

Hi, thanks for the reply Geoff.  I'm actually trying to access the %O
bytes sent that logio.c places amongst the other variables within the
logging module.  Thats something that I can't find elsewhere.  Sorry
about the %h %i example, i thought %O would over complicate the
question :)

Thanks,
Brad.

you might as well forget about %l - nobody runs with identd.  as for %h
you can use $r->c->get_remote_host()

http://perl.apache.org/docs/2.0/api/Apache2/Connection.html#C_get_remote_host_

mod_log_config merely uses the apache api to spit those bits out to the
log file.  so browse the Apache2::RequestRec, ::ServerRec, ::Conection,
etc and you'll have whatever info you need.
