Viewing performance statistics

The BASIC > Status page provides an overview of the health and performance of your Barracuda Web

Filter:

• Filtering statistics (such as threats blocked by the filtering rules, blocked visits to known

spyware Web sites, blocked downloads of spyware or viruses) for the past day and hour, as well

as total statistics since installation (or last reset) of the Barracuda Web Filter.

• Performance statistics, such as CPU temperature and system load.

• Subscription status for Energize Updates, Instant Replacement, and Premium Support.

• Lists of infected clients blocked Web requests.

• A set of bar graphs that illustrate an hourly breakdown of requests made by your users in the last

24 hours, and a set of bar graphs that illustrate a daily breakdown of requests made by your users

in the last 30 days. Both sets of graphs illustrate the following data:

• Number of requests blocked

• Number of requests received

• Number of kilobytes per second used by the requests allowed

Each bar graph is accompanied by two Top Ten lists: domains represented in the graph and Web

content categories represented in the graph.

Performance statistics displayed in red signify that the value exceeds the normal threshold.

Understanding the indicator lights

The Barracuda Web Filter has five indicator lights on the front panel that blink when the system

processes HTTP traffic.

Figure 3.3 displays the location of each of the lights.
