apache - Why can't I get Apache2 mod_dumpio working under Lucid Lynx Ubuntu?

Question

I did the following to try to set mod_dumpio up properly:

1. Used a2enmod to enable mod_dumpio
2. Changed LogLevel to "debug" in apache2.config
3. Added "DumpIOInput On", "DumpIOOutput On" and "DumpIOLogLevel debug" to apache2.config
4. Issued "/etc/init.d/apache2 restart" to restart Apache
5. Issued "apache2ctl -t -D DUMP_MODULES" to make sure mod_dumpio was loaded

I'm watching /var/log/apache2/error.log, but not seeing much there, and certainly not a dump of all input and output.

Can anyone help?

Answer 1

The problem was apparently that just one of my VirtualHosts (as defined in /etc/apache2/sites-enabled) had a LogLevel declared that was something other than debug, thus interfering with the overall behavior of mod_dumpio for reasons that escape me :)
