On occasion, the ProxySG appliance may generate an event log warning that does not seem to provide any information about the cause of the warning. For example:
"Health Monitor (WARNING): Health Check Status is 'WARNING'" 1 6F0101:1 Mailed notifier.cpp:125
You can refer to the ProxySG appliance Sysinfo (https://<IP_address>:<port>/Sysinfo) to investigate the cause of the warning.
Example of Using Sysinfo statistics to determine cause of health check warning
Use the following as a guideline for steps to take to determine the cause of the issue:
Stat: Health Check Status
Current State : OK
Last Transition : Sat, 09 Feb 2013 02:33:12 UTC
Current Value : OK
Notification Method : log, mail
fwd Domain name: 220.127.116.11
IP address: 18.104.22.168 Enabled OK UP
Last status: Success.
Successes (total): 44759 (last): Sat, 09 Feb 2013 03:11:15 GMT (consecutive): 228
Failures (total): 15 (last): Sat, 09 Feb 2013 02:33:01 GMT (consecutive): 0 (external): 0
Last response time: 44 ms Average response time: 45 ms
Minimum response time: 44 ms Maximum response time: 60 ms
Using these two entries, you can determine that the health check warning originates from a bad connection to a forwarding host. For more details, investigate the connections between the appliance and the forwarding host.
You can also use packet captures (PCAPs) to troubleshoot further.
