Should exist: mod_log_dbus?

[Andy Armstrong <an...@apache.org>]

(Apologies for posting here and on the modules list - it just occured  
to me that this might be a better place)

I'm playing around with log analysis at the moment - particularly  
real time analysis. Currently I just pipe logs through a Perl script  
that does the actual analysis. I'd quite like to be able to have  
multiple filters analysing the incoming log entries at the same time.  
I can of course do that just by building a pipeline of filters - but  
it starts to get messy.

So, I was looking at d-bus [1] and thinking how convenient it would  
be if I had a d-bus based logging module. Then I could just write  
filters that subscribed to the log messages. I could easily add,  
remove and restart filters without touching Apache.

I'm prepared to do some work on such a module but I don't want to do  
it if there's some obvious alternative I'm missing. Is this something  
that might be useful? Is there something out there already that I've  
missed?

I've been pointed in the direction of mod_log_spread which appears to  
do the same thing. My Google-fu is clearly weak - I didn't spot it :)

So I'm going to investigate that - and if it doesn't do what I think  
it should I'll either patch that (and submit the patches of course)  
or do mod_log_dbus - if I do I'll give you a shout. Thanks for the  
offer of help :)

Hi Brian,

I think this is another good example where one could use of your
mod_log_config with providers patch.  It should be fairy easy to write
provider for something like dbus.

This may not be the most appropriate place to discuss it, but I am 
willing to help do some work as well.  From the quick overview of dbus I 
just read, it doesn't look too complicated to do.
