=head1 NAME
 
multimemory - Munin plugin to monitor memory usage of processes. Which processes
are configured in client-conf.d
 
=head1 APPLICABLE SYSTEMS
 
Any system with a compatible ps command.
 
=head1 CONFIGURATION
 
There is no default configuration.  This is an example:
 
  [multimemory]
     env.names apache2 mysqld php-cgi
 
The names are used to grep with directly, after cleaning. So, this plugin
only supports very basic pattern matching. To fix: see multips

This plugin adds up the RSS of all processes matching the
regex given as the process name, as reported by ps.
