Device High Availability State Sharing Statistics for
Troubleshooting
The sections below describe the statistics you can view for each device and how you can use them to
troubleshoot your state sharing configuration for 7000 and 8000 Series device high-availability pairs.
Messages Received (Unicast)
Messages received are the number of high availability synchronization messages received from the paired
peer.
The value should be close to the number of messages sent by the peer. During active use, the values may not
match, but should be close. If traffic stops, the values should become stable and the messages received will
match the messages sent.
For troubleshooting, you should view both the messages received and the messages sent, compare the rate of
increase, and make sure the values are close. The sent value on each peer should be incrementing at
approximately the same rate as the received value on the opposite peer.
Contact Support if the received messages stop incrementing or increment slower than the messages sent by
the peer.
Packets Received
The system batches multiple messages into single packets in order to decrease overhead. The Packets Received
counter displays the total number of these data packets, as well as other control packets that have been received
by a device.
The value should be close to the number of packets sent by the peer device. During active use, the values may
not match, but should be close. Because the number of messages received should be close and incrementing
at the same rate as the number of messages sent by the peer, the number of packets received should have the
same behavior.
For troubleshooting, you should view both the packets received and the messages sent, compare the rate of
increase, and make sure the values are increasing at the same rate. If the sent value on the paired peer is
incrementing, the received value on the device should also increase at the same rate.
Contact Support if the received packets stop incrementing or increment slower than the messages sent by the
peer.
Total Bytes Received
Total bytes received are the number of bytes that make up the packets received by the peer.
The value should be close to the number of bytes sent by the other peer. During active use, the values may
not match, but should be close.
For troubleshooting, you should view both the total bytes received and the messages sent, compare the rate
of increase, and make sure the values are increasing at the same rate. If the sent value on the paired peer is
incrementing, the received value on the device should also increase at the same rate.
Contact Support if the received bytes stop incrementing or increment slower than the messages sent by the
peer.
