With the PTAP At-A-Glance report, you can see averaged metrics for your entire network. Data used for this report is generated in 15-minute intervals and the most-recent/last-collected sample is used.
To view an at-a-glance report, do the following:
The individual red gauge needles show the average for that specific metric across your whole company.
LWM = low water mark; HWM = high water mark. These abbreviations are below each gauge and indicate the lowest (and highest) value for each metric—across your whole enterprise for the sample (5-minute sample in the example shown above). The LWM/HWM values are helpful for quickly determining whether a device/circuit is not performing optimally.
To investigate further, run a Top Hitters report to find out which device/circuit is having a problem.
Many customers find it useful to know how to view summary metrics for a specific point in time. You also might want to create threshold rules so you can be alerted to changes in your network. And, if you ever need to find specific information, try using the PTAP map filters.
