+=head1 NAME
+
+services - Plugin to monitor number of processes of different services
+
+=head1 CONFIGURATION
+
+This plugin uses the following configuration variables
+
+ [services]
+   env.datafile		- Path to file which contains list of services (default: /root/munin/services.list)
+
+Datafile should contain lines which are used to detect number of running processes (ps ax | grep "LINE FROM FILE").
+If a number of processes of some service is below 1 (e.g. 0) critical event happens (configure your munin.conf about "contact.NAME.command" to send mail or something else;
+also nice line is 'contact.NAME.always_send critical' - not to stop sending alerts after critical event appears the first time).
+
+Datafile may contain comment lines (begin with "#"), empty lines and even regular expressions (WARNING - not tested, use carefully)
+Example of datafile:
+#############################
+# This line is a comment and next lines are names of some services
+sshd
+smbd
+nmbd
+lighttpd
+# Next line is an empty line
+
+named
+# Next line is a name of service with a path
+/usr/local/sbin/upsd
+# Next line is a line with spaces
+BackupPC -d
+#############################
+
+This plugin does not draw any graphs. It is only written to send alerts via mail or something else.
