“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, Matrix Server 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 Matrix Server 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 Matrix Server 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 system

event log.

“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 could occur if the Management Console is

out of date and does not support the version of Matrix Server running on

the server.

“Event” Status

The “Event” status is displayed when monitor_agent encounters an error

while executing the probe, Start, Stop, or Recovery scripts.

The status of the monitor may be “Up” even though an event has been

reported. This is the case if the error was not serious enough to stop the

execution of the script.
