=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.os freebsd
env.names apache2 mysqld php-cgi
Set env.os to freebsd if you are running this script on a machine which doesnt have
GNU sed installed (FreeBSD / OpenBSD / Solaris ...), else set it to linux.
The names are used to grep with directly, after cleaning. So, this plugin
only supports very basic pattern matching. To fix: see multips
=head1 INTERPRETATION
This plugin adds up the RSS of all processes matching the
regex given as the process name, as reported by ps.
=head1 MAGIC MARKERS
#%# family=manual
#%# capabilities=autoconf

0.3 light improvement in FreeBSD part of ps parsing
2010-05-28 08:58:50 +02:00
