Establishing a system baseline

Troubleshooting : How to troubleshoot : Establishing a system baseline

Before you can define an abnormal operation, you need to know what normal operation is. When there is a problem, a baseline for normal operation helps you to define what is wrong or changed.

Baseline information can include:

• Logging (see “Enabling log types, packet payload retention, & resource shortage alerts”)

• Monitoring performance statistics such as memory usage (see “System Resources widget” and “SNMP traps & queries”)

• Regular backups of the FortiWeb appliance's configuration (see “Backups”)

If you accidently change something, the backup can help you restore normal operation quickly and easily. Backups also can aid in troubleshooting: you can use a tool such as diff to find the parts of the configuration that have changed.
