I've been trying to setup a chart to monitor bandwidth usage for each Queue Tree we have, and I finally was able to create this by finding the correct OID using SNMPWalk.
Once I added the Data Source for each OID, I noticed the data it was charting was incorrect. Using a Scale of 1, showed the data but it was far too low compared to my interface charts. I then checked the Data Source for an Interface that I'm charting, and noticed it uses a Scale of 8. Once I changed the Scale to 8 for the Queue Tree, the chart data was accurate.
Why is it a scale of 8?
