The Cablemodem Detail page acts as a device profile screen, where you can get a quick snapshot of the last measured metrics. They appear as status boxes on the right side of the screen:
The first green box indicates the latest Downstream/Upstream bandwidth values, the grey box features the latest Transmission/Reception (Tx/Rx) values, while the blue box highlights the anomalies, such as Microreflections and SNRs (Signal-to-Noise Ratios). Lastly, the purple box indicates the status for the device, and the date and time for when these values were obtained. By default, we update these every 5 minutes.
Since the historic values for these three boxes are very important, you can click on the gear icon next to the main chart's period selector, and choose to visualize any of these metrics in a date range of your choosing.
