Sequence numbers seen in the system log entries are not in sequence.

• In PAN-OS, there is a field called Sequence Number assigned to different types of logs (System Logs, Traffic Logs, etc).
• It is a 64-bit log entry identifier incremented sequentially, and each log type has a unique number space.
• This Sequence Number can be used for tracking if all the logs of the same type are successfully generated.
• Exporting the system log to a file will display the sequence number.
• When exported, sometimes the sequence number are missing and not in sequence.
