Checking Status
Check the Basic > Status page for an overview of the health and performance of your Barracuda Link
Balancer, including:
• Utilization and status of the links.
• The subscription status of Energize Updates.
• System and hardware statistics, including CPU temperature and system load. Performance
statistics displayed in red signify that the value exceeds the normal threshold.
• Incoming and outgoing traffic statistics for each WAN link.
You can also view WAN link utilization and connection status by scrolling over the WAN port
graphic on the
Basic > Links page. View the status of VPN tunnels using the Services > VPN page.
Viewing Logs
The Barracuda Link Balancer provides three types of logs under the Logs tab:
• Event Log - general system events.
• Firewall Log - firewall events.
• VPN Log - information about VPN tunnels.
Using the Web user interface, you can delete the log, filter the log entries that are displayed or export
them to a CSV file.
View the system log displayed on the
Logs > Event Log page to see events that have occurred. These
include:
• Link status - A WAN link has become active or gone down; a link could not be detected.
• DHCP events - An IP address was handed out.
• Failed login attempts.
