=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.
