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. byproject_access

munin_byprojects_bandwidth

Count the total bandwidth used by each projects/vhost. Logtail is required. byproject_bandwidth

munin_byprojects_inout_bandwidth

Counts the in/out bandwidth used by each projects/vhost. Logtail is required. byproject_inout_bandwidth

Installation

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

In your munin plugin configuration file (for example, a new dedicated /etc/munin/plugin-conf.d/nginx_byprojects), configure the plugins:

  [byprojects_*]
  env.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. Each log is defined in a dedicated environment variable, named env.site.[siteName]. The value is JSON formatted.

  env.site.prod 	[{"path":"/home/prod/log/access.log"}]
  env.site.dev		[{"path":"/var/log/httpd/ssl-dev-access.log"}, {"path":"/home/dev/log/access*.log"}]
  env.site.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>

And restart the munin-node service.
