We've been running NPM for a few years now and have subsequently added NCM and NetFlow modules. Our data base at this time is running about 50GB. Below are some of our vital signs from the details window.
We've also got about 140 routers that we run NetFlow gathering off of, which I've heard is often the lion's share of the database contents.
We're making a brand new install of Orion on two new VMs (one poller, one SQL). We'd like at least to double our retention across the board.
Two questions:
Where does netflow fit into the retention numbers below (or has it got it's own setting in the netflow management window)?
---AND---
Can anyone recommend a good amount of disk to allocate for DB given these criteria?
