Background - I am having an issue with occassional pauses when streaming high-bitrate media across my home network to my smart TV. I *suspect* that the root cause is the (incredibly lame) 100 Mbps Ethernet interface in the TV.
In order to confirm that the peak bitrate really does max out the 100 Mbps connection, I'd like to monitor the communication between my NAS and the TV. The two devices are on separate VLANs, with routing performed by a CentOS 7 system, so it should theoretically be relatively simple to use an appropriate utility on the "router" to monitor and, if possible, graph the network traffic going to the TV.
Ideally, I could run said utility for the entire time that the media file is playing and then look at its pretty graph to check if/when the bitrate hit 100 Mbps. Being able to watch the pretty graph in real time through a web interface would be nice as well, but is not required.
Is any such program included in CentOS 7 or EPEL 7?
The closest thing that I've found thus far is iftop (despite its lack of pretty). Unfortunately, it won't allow me to see the peak bitrate over the whole period in which the media is playing.
Thanks for any suggestions!
