Store logvolume in gigabytes per day from FAZ

[PRosenlind]

Hi,

I'm trying to figure out a good way on how to log and store the logvolume from a specific adom in my FAZ overtime. I've looked into tapping into the API and/or Ansible but I haven't found anything that shows me this particular data. The data I want to store is the one obtained from the command:

diagnose fortilogd logvol-adom <adom>

Does anyone have any good tips for me on how to get this data stored in a good way? 

BR,
