Troubleshoot monitor problems
You may encounter the following problems with service and device monitors.
Monitor status
If the monitor status is not reported as Up, check the last error message string and
the last event message string that monitor_agent returned to HP Scalable NAS
for any service or device monitor on any server in the cluster. The error or event
message provides more status information.
“Down” status
The “Down” status indicates that the monitor finished its probe but it did not complete
successfully. Depending on the monitor type (such as HTTP or SMTP), the service
monitor probe may involve more than being able to connect to the network service.
For many built-in service monitors, HP Scalable NAS may conclude that the monitor
is down even if the TCP connection succeeds. For example, if a Web server is
available but the URL specified in the HTTP service monitor was not found, the HTTP
service monitor will be reported as Down.
“Undefined” status
If the probe has not completed because of a script configuration problem or because
HP Scalable NAS is still attempting to finish the first probe, the status will be reported
as “undefined” instead of Down.
“SYSTEM ERROR” status
The “SYSTEM ERROR” status indicates that a serious system functional error occurred
while HP Scalable NAS was trying to probe the service. To see details about the
system error, select the monitor on the Management Console, right-click, and select
View Last Error. Also view the cluster log file.
“Unknown” status
The “unknown” status indicates that the information that ClusterPulse provided to the
Management Console did not conform to one of the expected status choices. This
