LGTM. It may be best to add the unit of latency in the Y-axis for the latency panel.

If you can add the unit in the Y-axis for the latency, it will be good. If it is a time taking thing, please create a backlog ticket

Yes @agithomas. We can add the unit in Y-axis label. As per the readme file the latency is measured in milliseconds. So we will add ms suffix to the Y-axis.
