Viewing virus and intrusions status

Use the virus and intrusions status display to track when viruses are found by the FortiGate antivirus system and to track when the NIDS detects a network-based attack.

To view virus and intrusions status

1Go to System > Status > Monitor.

2Select Virus & Intrusions.

Virus and intrusions status is displayed. The display includes bar graphs of the number viruses and intrusions detected per hour as well as line graphs of the number of viruses and intrusions detected for the last 20 hours.

3Set the automatic refresh interval and select Go to control how often the web-based manager updates the display.

More frequent updates use system resources and increase network traffic. However, this only occurs when you are viewing the display using the web-based manager. The line graph scales are shown on the upper right corner of the graph.
