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out of date and does not support the version of Matrix Server running on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

The events are:

CONFIG_ERROR. A script must exist and be executable by root. This

condition is checked for probe, Start, Stop, and Recovery scripts each time

an attempt is made to execute the script.

SCRIPT_SYSERR. The monitor_agent tried to fork a process to execute the

script but the fork system call failed. This condition can occur when

Matrix Server is trying to execute probe, Start, Stop, or Recovery scripts.
