Panorama Log Storage Calculation

[s.williams1]

Ok so I guess my logs dont even collect for 24 hours due to my log storage being about 7GB. Silly people who set this up I swear. So I am trying to figure out how much I do need. 

I have a PA-500, PA-820, PA-3050 (x2, they are HA pair) and a PA-3020.

Now this article shows how many logs per second, but how do I determine what my log collection per day is? I assume its based on what logs I am collection and what sev level correct?

I just need to figure out how much space I need. Any tips trying to "guesstimate" that?

I can give you a guess,.. the document you linked has the best info. 

But how much bandwidth do you puch thought the device? do you log everything? how about how many Zones do you have?

I personaly wouldnt want less then 100gb.. storage is cheap these days and most server VM enviroments should be able to support that without batting an eye.  Just a guess without knowing the enviroment, and the amount of gear you listed. I would want at least 500gb, 750 to 1tb would be a dream, but thats a fight you got to have with your server guys!
