Audit Log

The audit log provides data about the operations of your ExtraHop system, broken down by component.

The audit log lists all known events by timestamp, in reverse chronological order.
If you experience an issue with the ExtraHop system, consult the audit log to view detailed diagnostic data

to determine what might have caused the issue.

Fingerprint

Fingerprints help secure appliances from machine-in-the-middle attacks by providing a unique identifier

that can be verified when connecting ExtraHop appliances.
When connecting an Explore or Trace appliance with a Discover appliance or Command appliance, make

sure that the fingerprint displayed is exactly the same as the fingerprint shown on the join or pairing page.
If the fingerprints do not match, communications between the devices might have been intercepted and

altered.
