Recent Logs
The system log displays the most recent high availability synchronization messages. The log should not display
any ERROR or WARN messages. It should remain comparable between the peers, such as the same number
of sockets being connected.
However, the data displayed may be opposite in some instances, for example, one peer reports that it received
a connection from the other peer and references different IP addresses. The log provides a comprehensive
view of the high availability state sharing connection, and any errors within the connection.
Contact Support if the log displays an ERROR or WARN message, or any message that does not appear to
be purely informational.

After you establish state sharing, you can view the following information about the configuration in the
State
Sharing
section of the High Availability page:
• The HA link interface that is being used and its current link state
• Detailed synchronization statistics for troubleshooting issues
The state sharing statistics are primarily counters for different aspects of the high availability synchronization
traffic sent and received, along with some other error counters. In addition, you can view the latest system
logs for each device in the high-availability pair.
