This script was born out of a desire to monitor and alert on cronjobs using Prometheus and Alertmanager. This script was inspired by https://janikvonrotz.ch/2020/09/07/monitor-cron-jobs-with-prometheus-grafana-and-node-exporter/ As far as I'm aware there isn't another facility for exposing metrics related to this in Node Exporter. This script receives two arguments, the description of the cronjob as a string and the exit status of the previous command. It prints the metric to stdout. Usage: ```bash <command> ; cronjob "<description>" $? ``` Example crontab entry: ``` * * * * * echo "Hello world!"; cronjob "greeting" $? | sponge /var/lib/prometheus/node-exporter/cronjob_greeting.prom ``` Example textfile: ``` [vagrant@rocky8 ~]$ cat /var/lib/prometheus/node-exporter/cronjob_greeting.prom node_cronjob_status{user="vagrant", description="greeting"} 0 ``` Signed-off-by: Alex Kraker <alex.kraker@benimbl.com>
Give this script a more descriptive name. This script will be seen in crontab files and this will be more descriptive of what the script is doing. Signed-off-by: Alex Kraker <alex.kraker@benimbl.com>
