cpuload_

Sadly there is no documentation for this plugin.

#!/bin/bash
#
# Munin-plugin to monitor the CPU usage for one or more given process name(s)
#
# Use the environment variable "process" to define more than one process
# name if required. Process names must be separated by comma, no whitespace.
#
# [cpuload_postfix]
# env.process master,qmgmr,proxymap,pickup
#
# GNU GPL, Bjørn Ruberg

# Find process names from env variables for the given plugin
# If not, extract from filename.

test -n "$process" || process=`echo $0 | cut -d _ -f 2`

if [ "$1" = "config" ]; then
    echo "graph_title CPU load for $process"
    echo 'graph_category processes'
    echo "graph_info This graph shows the CPU load for $process, as reported by 'ps'"
    echo 'cpuload.label CPU load'
    echo "cpuload.info CPU load of $process"
    echo "cpuload.type GAUGE"
    exit 0

echo -n "cpuload.value "
ps -C $process -o pcpu,comm --no-header | awk '{ sum += $1 } END { print sum }'
