• A Compass dashboard has a limit of 1,000,000 statistic items (protocols, flows, nodes, channels, WLAN, VLAN, data rates, applications) per second.

• For real-time captures, the Compass dashboard shows only the latest four hours of data. Every 10 minutes after the four hour mark, Compass slices off the first 10 minutes of available data. This limit can be adjusted through the Compass options dialog.

• Compass expects to receive packets in ascending order—a packet received with a timestamp earlier than the previous packet is discarded.

• There must be at least 500MB of free disk space or Compass stops generating/saving statistic information until enough disk space is made available.
