Chapter 9
Monitoring System Access and Performance
This chapter describes the system monitoring features of the VPN firewall. You can be alerted to
important events such as changes in WAN port status, WAN traffic limits reached, hacker probes
and login attempts, dropped packets, and more. You can also view status information about the
firewall, WAN ports, LAN ports, active VPN users and tunnels, and more. In addition, the
diagnostics utilities are described.
This chapter contains the following sections:
• “Enabling the WAN Traffic Meter” on this page
• “Activating Notification of Events, Alerts, and Syslogs” on page 9-5
• “Viewing Status and Log Screens” on page 9-9
• “Using the Diagnostics Utilities” on page 9-25
Enabling the WAN Traffic Meter
If your ISP charges by traffic volume over a given period of time, or if you want to study traffic
types over a period of time, you can activate the traffic meter for one or more WAN ports.
To monitor traffic limits on each of the WAN ports:
1. Select Monitoring > Traffic Meter from the menu. The WAN TrafficMeter tabs display, with
the WAN1 TrafficMeter screen in view (see Figure 9-1 on page 9-2).
The Internet Traffic Statistics section in the lower part of the screen displays statistics on
Internet traffic via the WAN port. If you have not enabled the traffic meter, these statistics are
not available.
Note: To receive logs by email, you need to configure the email notification server—see
“Activating Notification of Events, Alerts, and Syslogs” on page 9-5.
