I recently posted an article talking about HAProxy as a load balancer<\/a>. In the article I spoke about using a HTML health check file to maintain status of each servers Apache instance. The problem is this will flood your Apache server access logs every time this health check occurs, which I believe is every 2 seconds.<\/p>\n

So you end up with a log file like this:
\n\"\"<\/a><\/p>\n

To correct this issue we need to modify the apache2.conf<\/strong> file on each server, and explicitly tell Apache NOT <\/strong>to log this URI to the access logs. So, from the previous article<\/a> the culprit URI is \/healthcheck.html. Open your Apache configuration file.<\/p>\n

sudo vi \/etc\/apache2\/apache2.conf<\/pre>\n
Now add this above the CustomLog section:<\/p>\n
#logs \nSetEnvIf Request_URI \"^\/healthcheck.html$\" dontlog \nCustomLog \/www\/logs\/mysite_access_logs combined env=!dontlog \nErrorLog \/www\/logs\/mysite_error_logs<\/pre>\n
NOTICE: <\/strong>Make sure you have the ” escape character for any special characters.<\/p>\n
That’s it! No more spamming of all the health checks to our Apache logs!!<\/p>\n
