Add support for outputing apache access and error logs to loggregator about cf-php-apache-buildpack

[dmikusa]

This is definitely something that I want to add. I'm in the middle of restructuring the build pack at the moment. After that work is done, I'll make sure to add this.

In regards to prefix, I'm not exactly sure I understand what you mean there. Do you mean the LogFormat should be prepended with the literal text "s=access"? Is this something understood by loggregator? or is it purely for organizational purposes?

LogFormat "s=access %h %l %u %t \"%r\" %>s %b" common

In regards to the ErrorLog, I think you can format this, but only in 2.4.x. I don't think 2.2.x supports custom formats.

Great thanks!

The prefix won't be processed by the loggregator but is a way to add meta data to the log entries to that clients can sort them and try to reconstitute distinct files out of the stdout/stderr streams. Having the prefix formatted as a key/value pair makes it easy for most log processors to then filter logs using them.
