Time Based Group Statistics
Use the Time
Based Group Statistics page to define criteria for collecting time-based
statistics for interface traffic. The time-based statistics can be useful for
troubleshooting and diagnostics purposes. The statistics application uses the system clock
for time-based reporting, so it is important to configure the system clock (manually or
through SNTP (Simple Network Time Protocol))
before using this feature.
