SPAM: : Checking for Apache Errors

[Paul Weaver]

I just ran through a 639,000 line gz compressed apache log file, using
zcat access.log.gz|awk '{print $9}'|sort|uniq -c in 7 seconds
 
That gives you the return code (404, 302, 200), and the number.
Percenting it is an exercise for the reader, but something like
 
tac /var/log/apache/access.log|head -10000|awk '{print $9}'|sort|uniq -c

There is no time like the present for postponing what you ought to be
doing.

	I would really recommend Splunk for this task over
Nagios...assuming you don't generate more than 500 MB of logs per day,
it's free! Assuming you really wanted to do it in Nagios, you'd probably
be stuck writing your own plugin in C in order to make it fast enough to
comb throw MB of logs without too much overhead (like the Nagios
avail.cgi does...)

	I'm trying to check my apache logs to make sure there is not
more than a reasonable number of 404 errors for any given chunk of time.
Does anyone have a apache log checking plugin?  I would prefer something
that allowed me to alarm if the number of 404s exceeded a certain
percentage.
	
	I didn't see anything on nagiosexchange, and check_log is a bit
too generic for what I'm trying to do.
	
	If nothing exists, I'll probably write something.
