Supervisor Module Redundancy Statistics

The active supervisor periodically sends a health report message to the
standby (redundant) supervisor. If the standby supervisor is enabled, it
responds with a health report reply.

Health report statistics are displayed on the CPU Redundancy Status Web
page. To view this Web page, expand the System > Configuration > CPU
Redundancy
folders, and then click Status/Statistics. The following
statistics are displayed:

Health Reports Sent - Displays the number of health reports sent.

Health Reports Received - Displays the number of health reports
received.

Health Reports Timeouts - Displays the number of health reports
timeouts.

Health Reports Missed - Displays the number of health reports
missed.
