Short-Description: carbon-cache init script

Description: An init script for Graphite's carbon-cache daemon.

END INIT INFO

Author: Jeremy Chalmer

#

This init script was written for Ubuntu 11.10 using start-stop-daemon.

Note: Make sure you set the USER field in /opt/graphite/conf/carbon.conf to be the same

user that owns the /opt/graphite/storage/ folder. Carbon-cache will be invoked as that

username on start.

#

Enable with update-rc.d carbon-cache defaults

Source init-functions:

#source /lib/lsb/init-functions
. /lib/lsb/init-functions

PATH should only include /usr/* if it runs after the mountnfs.sh script

PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

Path to Graphite

GRAPHITE_HOME=/opt/graphite

Name of executable daemon

NAME=carbon-cache
DESC=carbon-cache

#Carbon has its own logging facility, by default in /opt/graphite/storage/log/carbon-cache-*

Path to Executable

DAEMON=$GRAPHITE_HOME/bin/carbon-cache.py

NOTE: This is a hard-coded PID file, based on carbon-cache.py. If you have more the one carbon-cache

instance running on this machine, you'll need to figure out a better way to calculate the PID file.

PIDFILE=/opt/graphite/storage/carbon-cache-a.pid

SCRIPTNAME=/etc/init.d/$NAME

Exit if the package is not installed

if [ ! -x "$DAEMON" ]; then {
echo "Couldn't find $DAEMON or not executable"
exit 99
}
fi

Load the VERBOSE setting and other rcS variables

[ -f /etc/default/rcS ] && . /etc/default/rcS

Function that starts the daemon/service

#
do_start()
{

Return

#   0 if daemon has been started
#   1 if daemon was already running
#   2 if daemon could not be started

    # Test to see if the daemon is already running - return 1 if it is. 
start-stop-daemon --start --pidfile $PIDFILE \
    --exec $DAEMON --test -- start > /dev/null || return 1

    # Start the daemon for real, return 2 if failed
start-stop-daemon --start --pidfile $PIDFILE \
    --exec $DAEMON -- start > /dev/null || return 2

}

#

Function that stops the daemon/service

#
do_stop() {

Return

#   0 if daemon has been stopped
#   1 if daemon was already stopped
#   2 if daemon could not be stopped
#   other if a failure occurred
log_daemon_msg "Stopping $DESC" "$NAME"
start-stop-daemon --stop --signal 2 --retry 5 --quiet --pidfile $PIDFILE
RETVAL="$?"
[ "$RETVAL" = 2 ] && return 2

    # Delete the exisitng PID file
if [ -e "$PIDFILE" ]; then {
    rm $PIDFILE
}
    fi

    return "$RETVAL"
