I am snmp polling WAN interface of firewall getting input and output bytes. How do i create average of 5 minute, 1 hour and 1day average graphs?

i have the snmp polling and netflow 9 interface utilization data.

There are two different questions that you might be asking, so I will try to give both answers. You should probably use TSVB for this kind of data. If the values are _monotonically increasing_, then you should use the "Positive rate" function to calculate the average increase per interval. Then, this is the conditional part:

- You might want to set the overall interval to 5 min, 1 hour, or 1 day- by default this will give you something like "Rate per 5 min" or "Rate per 1 hour" but you can scale this using the "Positive Rate" function to something like "Rate per 1 min over a 5 min period", or "Rate per 1 hour over a 1 day period"- this is basically sub-dividing the interval into smaller chunks
- Instead of sub-dividing intervals, you might want to smooth out a smaller interval into the 5-min average using the Moving Average. In this case, I would suggest that you don't use Positive Rate, and instead use the Moving Average of the Average.
