scanerrlog - Generate summaries/reports from Apache error logs

17 Jun, 2009  Tips

scanerrlog offers the possibility to generate a summary or report about Apache errors and sort them depending on how frequent they are.

To install it (for Ubuntu users):

sudo apt-get install scanerrlog

or use Synaptic and search for scanerrlog.

It's written in Python, and it is very easy to use it. (type 'man scanerrlog' in a terminal to see the manual page)

I tested it with Apache2 log files using the following command:

scanerrlog -f text -o /tmp/log.txt /var/log/apache2/*.log
  • -f : format (text, pdf, html, xml)
  • -o : output file
  • args : log files


And it produces the following text file (I stripped personal info from it):

The html output is also very neat, you can try it with something like:

scanerrlog -f html -o /tmp/log.html /var/log/apache2/*.log
