Supported actions
Real-time data section
Each metric (rectangular box) is correlated to a chart at the bottom of the page. Click a rectangular box to show or hide the correlated chart.
When the color of a rectangular box is blue, the correlated chart is shown. Otherwise, the chart is hidden.
Chart section
You can hover your mouse cursor over a chart to view the data collected at the specific time.
There is a time axis under most of the charts. You can move the blocks at both ends of the time axis to view the data collected within the specified time frame.
Some charts contain multiple metrics. The names and icons of the metrics are displayed at the top of the carts. These metrics use the same color as the corresponding curves in the charts. Click the icon of a metric to show or hide the metric in the chart.
