The MPchart statistics app from InterWorking Labs displays real-time graphs showing selected parameters for uni-directional flows in the Maxwell Pro impairment engine. Enter the IP address and default port 7021 for your Maxwell Pro server, then press Connect: the app will establish a TCP connection to retrieve statistics. You can set the sample rate from 1/8 second to 120 seconds, and store up to 600 samples. The graph shows two waveforms per graph, as well as the network link state for both ports. For each waveform, select the metric to track, and units to display, in either total counts (bits, bytes, packets), or a rate (bits/sec, bytes/sec, packets/sec). You can reset the total counts for each graph to start counting up from zero. The In and Out metrics have "volume-style" meters that show real time activity: tap to switch between measuring bit/sec or packets/sec. You can add/delete multiple graphs, and enter a name for each graph . Warning icons appear if you choose a flow that will not have packets flowing through it.
