List of Plugins

The FileCount plugin does something very simple: Count the number of files in a directory and all its subdirectories. This can be used for a variety of statistics, for example the queue length of an MTA, the number of PHP sessions of a web server or simply the number of files in your home directory.

In addition to the number of files, the plugin also collects the total size of all files. Think: du(1).

In come cases collecting all files in a directory is not desired. For instance, the session files of the CGI::Session Perl module reside in /tmp. But counting all files in /tmp doesn't tell you anything about the number of sessions. For this reason the plugin also allows you to specify which files to count. Files can be selected by:

  • Name (shell wildcards)
  • Size
  • Modification time

This plugin is a generic plugin, i.e. it cannot work without configuration, because there is no reasonable default behavior. Please read the Plugin filecount section of the collectd.conf(5) manual page for an in-depth description of the plugin's configuration.
