Monitoring
The VPN 3000 Concentrator tracks many statistics and the status of many items essential to system
administration and management. This section of the Manager lets you view all those status items and
statistics. You can even see the state of LEDs that show the status of hardware subsystems in the device.
You can also see statistics that are stored and available in standard MIB-II data objects.

Monitor

This section of the Manager lets you view VPN Concentrator status, sessions, statistics, and event logs.
•Routing Table: current valid routes, protocols, and metrics.
•Event Log: current event log in memory.
•System Status: current software revisions, uptime, SEP modules, system power supplies, Ethernet
interfaces, WAN interfaces, front-panel LEDs, and hardware sensors.
•Sessions: currently active sessions sorted by protocol, SEP, and encryption.
–Top Ten Lis ts: “Top ten” sessions sorted by data, duration, and throughput.

These Manager screens are read-only “snapshots” of data or status at the time the screen displays. Most
screens have a Refresh button that you can click to get a fresh snapshot and update the screen, but you
cannot modify the data on the screen.
You can also configure the Manager to automatically refresh all the screens in this section except the
Event Log. See Administration | Monitoring Refresh.
