54 Barracuda Load Balancer Administrator’s Guide
The following table describes the various health indicators displayed for Real Servers.
Viewing Performance Statistics
The
Basic > Status
provides an overview of the health and performance of your Barracuda Load
Balancer, including:
•
Traffic statistics, which shows the number of load-balanced requests for various types of traffic
since the last system reset, for example, the number of load-balanced HTTP requests.
•
The subscription status of Energize Updates.
•
Performance statistics, such as CPU temperature and system load. Performance statistics
displayed in red signify that the value exceeds the normal threshold.
•
Hourly and daily traffic statistics.
Viewing the Event Log
The
Basic > Event Log
page maintains a list of all noteworthy events that affect the Barracuda Load
Balancer, such as attacks upon various Services and status changes for a Real Server.
Automating the Delivery of System Alerts
The
Basic > Administration
page
allows you to configure the Barracuda Load Balancer to
automatically email notifications to the addresses you specify. To enter multiple addresses, separate
each address with a comma. An email notification is generated if the number of operating Real
Servers for a Service falls below a preset threshold.
Viewing System Tasks
The
Advanced > Task Manager
page provides a list of tasks that are in the process of being performed
and also displays any errors encountered when performing these tasks.
Some of the tasks that the Barracuda Load Balancer tracks include:
•
Cluster setup
•
Configuration restoration
If a task takes a long time to complete, you can click the
Cancel
link next to the task name and then
run the task at a later time when the system is less busy.
The Task Errors section will list an error until you manually remove it from the list. The errors are not
phased out over time.
