I created some custom scripts to monitor things such as who logs in, load average, temps, etc. I set these up so they would send a warning to my discord server. These scripts required root privs, so added them to the root crontab. They didn't survive a reboot. Is there a way to add custom cron jobs that will survive a reboot or upgrade? I know that we have nrpe plugin, but I don't want to have another server just to receive nrpe notifications. This works without the headache or cost of another server running.
Hi,
Have a look at:
https://docs.opnsense.org/development/backend/configd.html
Of particular note is adding a "description" field which allows your custom actions to be added to the GUI under System: Settings: Cron where you can use it as required.
Cheers,

Thanks much. I will look at that. It didn't occur to me to use configd for custom cron scripts.
You may also define your cron jobs in "/etc/cron.d/crontab".
