SolarWinds Quality of Experience agent computation of bandwidth consumption


How does the SolarWinds Quality of Experience agent compute bandwidth consumption?


The SolarWinds Quality of Experience agent uses the following formula to compute bi-directional bandwidth consumption:

Total 2-way bandwidth bps = 2 x (3,000 + (100,000 / tp )) ,

where tp is the time poll interval, in seconds. The default value of tp is 300 seconds.

Example Calculations:

The total bandwidth (bps) for 10 packet analysis sensor agents, communicating in both directions, for one hour, where the time poll interval is the default, 300 seconds.

Total 2-way Bandwidth (bps) = 10 x (2 x (3000 + (100,000 / 300)))
  = 10 x 2 x 3,333 bps
  = 66,666 bps
  = 66.67 kbps
Total Data Throughput (B) = (Total Bandwidth bps) x (60 sec/min) x (Total Polling Time min) / (8 bits/byte)
  = (66,666 bps) x (60 sec/min) x (60 min) / (8 bits/byte)
  = 29,999,700 bytes
  = ~30 MB
