My line in /etc/crontab looks like this:
*/5 * * * * root /usr/local/sbin/watchdog.cfengine
The script that is called via cron contains:
/bin/sh
processname="cf-execd"
if ! [ `pidof $processname` ] ; then
$processname
logger -t WATCHDOG "$processname not running, tried to restart
$processname"
fi
The init.d script is as follows:
#! /bin/sh
#####################################################################
# /etc/init.d/cfengine3 (Client)
#
# Init script for cfengine3
#
# This file is protected by cfengine. Whatever you do,
# it will be changed back to a promising state.

And finally, here's the /etc/default/cfengine3:
#####################################################################
# /etc/default/cfengine3 (Client)

# Cfengine3 default configuration

# This file is protected by cfengine. Whatever you do,

#####################################################################
# Set variable to 1 to start the daemon; 0 otherwise.
RUN_CF_SERVERD=0
RUN_CF_EXECD=1
RUN_CF_MONITORD=0
I got this somewhere off the internet, and I had zero problems so far.
Cheers,
Robert
