Hard Disk Monitoring

I am running a 6 drive Synology NAS. Any thoughts about creating a pkg to install on a Synology NAS?

Please check the page:

and the tutorials on the bottom about how to configure NAS hard disk drive monitoring.
There are two specific tutorials available for Synology NASes, probably they will help about how to configure on your device too.
