# Munin-plugin to monitor processes on Linux

# FreeBSD, OpenBSD, NetBSD, Solaris and OSX.

#

# Require munin-server version 1.2.5 or 1.3.3 (or higher).

#

# This plugin is backwards compatible with the old processes-plugins

# found on SunOS, Linux and *BSD (i.e. the history is preserved).

#

# All fields have colours associated with them which reflect the type

# of process (sleeping/idle = blue, running = green,

# stopped/zombie/dead = red, etc.)
