contrib-munin/plugins/apache/apache_byprojects

The 'byprojects' family

Those plugins are used to monitor different projects or vhost (i.e. either different log files or using regular expression as filters) on the same web server.

munin_byprojects_access

Count the number of hits per projects/vhost.

munin_byprojects_bandwidth

Count the total bandwidth used by each projects/vhost. [Logtail] (https://www.fourmilab.ch/webtools/logtail/) is required.

munin_byprojects_inout_bandwidth

Counts the in/out bandwidth used by each projects/vhost. [Logtail] (https://www.fourmilab.ch/webtools/logtail/) is required.

Installation

The setup is pretty straight forward. First you need to configure the plugin:

Define the path to logtail:

  $logtail = '/usr/local/bin/logtail';

Multiple logs can be used for the same project/vhost and a regular expression (regex) can be used as a filter:

  my %logs = (
    'prod' => [
                {'path' => '/home/prod/log/access.log'}
              ],
     'dev' => [
                {'path' => '/var/log/httpd/ssl-dev-access.log'},
                {'path' => '/home/dev/log/access.log'}
              ],
    'test' => [
                {'path' => '/var/log/access.log', 'regex' => '"[A-Z]+ /test/'},
                {'path' => '/home/test/log/access.log'}
              ],
  );

In the previous example the prod project graph will be using everything in /home/prod/log/access.log. The test project will be using eveything in /home/test/log/access.log and stuff that match '"[A-Z] /test/' in /var/log/httpd/access.log (e.g. "GET /test/).

Then link the file just as any other plugins.

  ln -s /usr/local/sbin/<plugin> /usr/local/etc/munin/plugins/<plugin>
