Duply: notify backup exit status to Zabbix

I’ve started using duplicity with duply since some time, and I’m quite happy with it.

I also use Zabbix, and I’m very happy of it! How to combine the two? Pretty easy: duply has the ability to run a command after the execution of a backup.

Change PROFILE according to your setup, create ~/.duply/PROFILE/post with the following content:

#!/bin/sh

if [ ! -f /etc/zabbix/zabbix_agentd.conf ] ; then
	# No zabbix installed
	exit 0;
fi
/usr/bin/zabbix_sender -z $(grep ^Server= /etc/zabbix/zabbix_agentd.conf |cut -d= -f2|cut -d, -f1) \
                 -s $(grep ^Hostname= /etc/zabbix/zabbix_agentd.conf |cut -d= -f2|cut -d, -f1) \
                 -k duply.backup -o $CMD_ERR > /dev/null

exit $?

Make it executable with

chmod +x ~/.duply/PROFILE/post

And make sure you have zabbix-sender package installed!

apt install zabbix-sender

Now that we have prepared Duply let’s move on Zabbix frontend and create the check item like the one in the image (bonus: there’s a template exported below):

Duply status Zabbix item

This will be the receiver of the zabbix-sender command we will launch in the post. The type Zabbix trapper is just a way to make it kind of passive item. Now you can create the triggers you want, for example if the last value is not 0 it means the backup didn’t complete successful. Or, since it’s a passive item, if there’s no data in the last x hours the backup didn’t run:

If you’re fit with the examples above you can download and import my template for Zabbix 3.0, and apply it to any host running duply.
