To get a useful chart out of amCharts, there are three main steps we need to follow:ġ. We want to present all of the data to them, but we want to do it simply. For this scenario, management wants to have an explanation of what happened and why there was customer impact. In the case of this issue, there was a bad wire causing the connection to incur significant packet loss. The purpose of this chart is to visualize the representation between TCP retransmissions and HTTP throughput. In this example, we will be creating the chart above using AmCharts. The amCharts chart, however, is clean, concise, and easy to read. It’s limited in presentation options, and honestly is an overwhelming amount of buttons and knobs. These charts display the same information – the count of HTTP packets sent, as well as the count of TCP retransmissions.Īs we can see, the default display of data out of the Wireshark IO Graph is not ideal. Let’s take a look at the below screenshots. The interface of amCharts then gives us endless flexibility to modify and present our data. In our case, we’ll be using output from Wireshark. Check chart demos to see all the charts in action.ĪmCharts allows us to quickly upload any type of CSV data to be displayed. You can download, try and even use our charts for free. Our charts is a completely standalone and independent library, which doesn’t require any 3rd party includes. Our charting solution include Column, Bar, Line, Area, Step, Step without risers, Smoothed line, Candlestick, OHLC, Pie/Donut, Radar/ Polar, XY/Scatter/Bubble, Bullet, Funnel/Pyramid charts as well as Gauges. We’ll be using an online tool called amCharts to create our graphs using data form Wireshark.ĪmCharts is an advanced charting library that will suit any data visualization need. In some cases though, we need to provide that data in a more visually appealing manner. The IO Graph in Wireshark is fantastic for getting the bare information out of the tool to communicate to others. Does that make it a better ( more accurate) graph or a worse graph? I want to clearly communicate (and understand) the change that was made, but I also don't want to mislead (them or myself) as to how effective it was.In this article, we’re taking a look at a method for improving the visual appeal of the Wireshark IO Graph. Is there maybe a command line tool that will do that kind of analysis for me? or just some window in wireshark that I'm missing that will let me get stats like that for a given period of time?Īnd of course pretty graphs? Or even something that will give me a csv or something with values from the filters I give it? With that I could just throw it in excel and go from there.ĮDIT: Also, if I use smoothing in my graph it shows a much, much stronger difference between the before and after captures. I'm sure I could try to slice the pcaps up, filter out everything before/after the tests, and just try and get a count that way, but it feels like there should be a better way. Something like: Test 2:ĭup-acks during test (packets per second):ĭup-acks during test other endpoints (packets per second): Hell, even getting that information into a table would be awesome.
dynamic? integrated? opposite of me drawing lines across screen captures in MSPaint? It get's the job done, sort of, but I was hoping for something that was a bit more, um. That works for me, but isn't going to fly when I show this to anyone else. I can see the results in the capture IO graph, but only if I squint and use the logarithmic scale and wiggle the graph back and forth so that the peaks are next to the scale on the side of the graph. So I'm having some trouble trying to effectively quantify the results of a network modification.
