[Observium] observium database size

Hi....

Just a silly question. I was googling around for number but could not find meaningful reallife data.

I am running now an observium instance for about a year. I am polling presently 22 serves, 14 switches and 1 printer. Alltogether 1004 ports. My mysql database is now 189 GB big. I need to resize my filesystem soon.

Attached you can also find my statistics output from observium

Is this database size normal? How big can it grow? in one year? In 2 years? Is there an upper ceiling? What are your database sizes (maybe in a similar scenario)?

Thanks for your help,

Roland
