Disk space filling with apache logs

[stebbo]

Hi All,

I've been getting warnings from the localhost system regarding the falling amount of free space on my system. I only have an 8GB hard drive, and a little bit of exploring shows me that I have 2.6GB taken up by the apache log files in /var/log/httpd

How can I reduce the size of these log files? The system appears to be keeping the last 4 week's worth of log files in addition to the current file, each around 500-700MB in size.

Thanks in advance,
Chris.

What is in those log files? I bet there are a few lines that repeat ad nauseam. Could you take a look at the logs and post any oft-repeated lines?

I gather this is logging every single request - come to think of it I have a few machines around the place continually logged in on my dashboard page which is a minemap of the entire installation. from the above it seems every refresh of each of the couple of hundred green/red lights is logged?

Cheers,
Chris.

I'm thinking I can probably just turn off these logs and turn them back on again if I'm interested in looking at them in the future.

How might I go about turning off logging to the access_log files?

Cheers,
Chris.

I would personally suggest setting up a 5-7 day log rotate instead, but if you really wish to disable them entirely. You are going to want to modify /etc/httpd/conf/httpd.conf and look for the CustomLog and ErrorLog directives. Simply commenting them out with # first should do the trick after an apache restart.

Hi sreinhardt,

thanks for the response. I I'll look into log rotate. For the moment I've lowered the logging level to error rather than warning and will see what that produces.

Cheers,
Chris.
