CPU Usage Graphs
CPU Usage graphs enable the administrator to monitor the CPU usage by the users and system components. Graphs display percentage wise minimum, maximum, average and current CPU usage for user, system, and CPU idle time.
• X-axis –Minutes/hours/days/months (depending on the period selected)
• Y-axis – % use
Legend:
• Orange color – CPU used by user
• Purple color – CPU used by system
• Green color – CPU idle time

Memory Usage Graphs
Memory Usage graphs enable the administrator to monitor the memory usage in Megabytes(MB). Graph displays percentage wise minimum, maximum, average and current memory used, free memory and total memory available.
• X-axis –Minutes/hours/days/months (depending on the period selected)
• Y-axis – Memory used in MB
Legend:
• Orange color – Memory used
• Purple color – Free memory
• Green color – Total memory

Load Average Graphs
| Monitor and Analyze | 36
Load Average graphs enables the administrator to monitor the load on the system.
Graphs display the minimum, maximum, average and current load on the system at the interval of one minute, five minute, and fifteen minutes.
• X-axis –Minutes/hours/days/months (depending on the period selected)
• Y-axis – Load average index
Legend:
• Orange color – One minute
• Purple color – Five minutes
• Green color – Fifteen minutes

Disk Usage Graphs
Disk Usage graphs enable the administrator to monitor the disk usage in percentage.
Graphs display the minimum, maximum, average and currently used disk space in percentage by Signatures, Config,
Reports and Temp files.
• X-axis –Minutes/hours/days/months (depending on the period selected)
• Y-axis – % use
Legend
• Orange color – Disk space used by signatures
• Purple color – Disk space used by config files
• Green color – Disk space used by reports
• Blue color – Disk space used by temp

Live Users Graphs
Live Users graphs enable the administrator to monitor the number of live users for the selected time duration.
Graphs display the number of users currently connected to the Internet. In addition, it shows the minimum, maximum and average number of users connected during the selected period.
This helps the administrator in determining the peak hour of the day.
• X-axis –Minutes/hours/days/months (depending on the period selected)
• Y-axis – Numbers of users
Legend
• Orange color – Number of live connected users

Data Transfer through WAN Zone Graphs
| Monitor and Analyze | 38
Data Transfer for WAN zone graphs is subdivided into three (3) graphs providing various information about data transfer via WAN zone.
1. Total upload/download data transfer of the selected period – Graph displays combined graph of upload & download data transfer. Colors differentiate upload & download data traffic. In addition, it shows the minimum, maximum and average data transfer for upload & download traffic individually.
• X-axis –Minutes/hours/days/months (depending on the period selected)
• Y-axis – Upload/download in KBits/second
Legend
• Orange Color - Upload traffic
2. Total data transfer of the selected period - Graph displays the total data transfer from the WAN zone. In addition, it shows the minimum, maximum and average data transfer.
• X-axis –Minutes/hours/days/months (depending on the period selected)
• Y-axis – Upload/download in KBits/second
Legend
• Orange Color - Total (upload + download) traffic
• Purple Color - Download traffic
3. Gateway wise total data transfer of the selected period - Graph displays the gateway-wise data transfer from the WAN zone. In addition, it shows the minimum, maximum and average data transfer of each gateway.
• X-axis –Minutes/hours/days/months (depending on the period selected)
• Y-axis – Upload/download in KBits/second
Legend
• Different color for each gateway
