How to Use

mkdir -p /etc/zabbix/scripts
cd /etc/zabbix/scripts
curl -O https://raw.githubusercontent.com/sebastian13/zabbix-template-rescript/master/scripts/log-rescript.sh
curl -O https://github.com/sebastian13/zabbix-template-rescript/blob/master/scripts/rescript-repo-discovery.pl

2. Upload the template zbx_template_rescript-backup to Zabbix Server and assign it to a host

3. Run the script after each rescript call

Examples

• As simple as

   rescript reponame && /etc/zabbix/scripts/log-rescript.sh

• Running as cronjob, I'm reccomending using chronic from moreutils

   26 3 * * * chronic rescript reponame && chronic /etc/zabbix/scripts/log-rescript.sh

• Within a script

   #!/bin/bash
   
   set -e
   
   # Rescript's automatic function (https://gitlab.com/sulfuror/rescript.sh/wikis/usage)
   # reads the "LOGGING" variable. By default, the "LOGGING" variable is set to "yes".
   # This will create a log file with the output, which is necessary for this script.
   rescript example.repo.1
   # Run this script after each "rescript ..." call.
   source /etc/zabbix/scripts/log-rescript.sh
   
   # If using a rescript command, you have to use the logging flag -l or --log
   # to create a logfile, which is necessary fort his script.
   # -l, --log: create log file with command output.
   rescript example.repo.2 backup -l
   source /etc/zabbix/scripts/log-rescript.sh
   
   # This script will also log the output of a restic check.
   # -C, --check: check for errors in repository
   rescript example.repo.2 backup -lC
   source /etc/zabbix/scripts/log-rescript.sh
   

Adjust Triggers
