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.

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.
