Performance

Performance graphs allow you to monitor Content Gateway performance and analyze network traffic. Performance graphs also provide information about virtual memory usage, client connections, and so on.

Performance graphs are created by the Multi Router Traffic Grapher tool (MRTG). MRTG uses 5-minute intervals to accumulate statistics.

Performance graphs provide the following information.

Statistic Description
Overview Displays a subset of the graphs available.
Daily Displays graphs that provide historical information for the current day.
Weekly Displays graphs that provide historical information for the current week.
Monthly Displays graphs that provide historical information for the current month.
Yearly Displays graphs that provide historical information for the current year.
Important: To run the Multi Router Traffic Grapher tool in Linux, you must have Perl version 5.005 or later installed on your Content Gateway system.

A description is given adjacent to each graph. Click on a graph to get the daily, weekly, monthly, and yearly on a single screen.
