Check for and report on PHP Fatal Errors in the logs about apache2buddy

[richardforth]

While technically we are drifting into application land, I added this because parsing apache error logs is in theory an apache administration task. So, This does not come under "scope creep" and I am happy to work on this if it is popular.

[richardforth]

Slight snag though, apache2buddy has traditionally only scanned the generic apache error log in /var/log/httpd/[error.log / error_log](depending on distro).

Would it be worth the time scanning all the error logs and reporting on each one individually? What if they have 200 vhosts with individual log files? Hmmm. Also would this produce too much data? No, not if we limit it to the top 5 maybe.But the 200 vhosts = 200 logs....still thats a lot of output. It might take too long.

Thoughts?

Kept it simple for now, similar to maxclients hit detection, show last 5 PHP Fatal Errrors

Only checking the main error log in apache, not sure if php fatal errors are logged in both vhost AND main error logs or not.

may adjust code slightly
