So, a speed test can show bandwidth but so can a graph, when you see the flat line, you've hit your limit.
Use interface counter graphs to map out b/s and then you'll be able to see where you're actually maxing out. If you've hit a bandwidth limit on a connection but your graph is still spiky it's not you it's them.
But if he wanted that historical data for, say, making sure an ISP delivers promised bandwidth, then unless he’s constantly maxing out the connection, the usage graph is going to be fairly useless.
Yes, but doing a speed test while you're using the link isn't an accurate test, so it's extremely difficult to be able to show bandwidth issues with anything other than a graph. If the ISP is not giving you your full bandwidth, you'll flatline below the full bandwidth on the graph. If you are using half your link and do a speed test you will only get results for about half your link unless you drop all other traffic to do the speed test.
