17 LINKMON Log Messages
This section describes, in alphabetic order, the log messages that a LINKMON process can write
to the system log, $0, during LINKMON initialization.
General Information
The LINKMON process in a processor does not begin initialization until it receives a
SERVERCLASS_SEND_ call from a Pathsend process executing in its processor. If an error occurs
during LINKMON initialization, the LINKMON process:
• Returns an error to the application (Pathsend error 947, file-system error).
• Writes a message to $0 indicating the reason for failure.
• Waits ten seconds before processing any additional SERVERCLASS_SEND_ calls, so that
subsequent sends to the uninitialized LINKMON process do not flood $0.
Each subsequent SERVERCLASS_SEND_ call in this processor causes the LINKMON process to
reattempt initialization; after the error condition is corrected, the LINKMON process can complete
initialization.
The LINKMON log messages are type 512 event messages that you can display from $0 with an
EMS printing distributor or ViewPoint. For more information, see the EMS Manual or the ViewPoint
Manual. Although type 512 messages are sent to the EMS collector $0, they are not included in
the Operator Messages Manual; that manual contains only numbered messages.
Some LINKMON messages have file-system errors associated with them. For a description of
file-system errors, see the Guardian Procedure Errors and Messages Manual.
All LINKMON log messages have the following format:
LINKMON ( LINKMON-process-name | CPU,PIN ) - message-text
where message-text is one of the messages described in this section.
LINKMON Log Messages
These messages are generated by LINKMON processes:
Failed to get length bytes of extended memory
Cause. The LINKMON process was unable to obtain sufficient memory to continue running.
Effect. The LINKMON process is unable to process SERVERCLASS_SEND_ calls. This message is
always followed by an EMS message that describes why the LINKMON process could not obtain
enough memory.
Recovery. Recovery depends on the error that occurs. For example, if the next message is
“SEGMENT_ALLOCATE_ error 1 (error detail 43) on swap file $SYSTEM.ZLINKMON.ZZLM04,”
you must make additional disk space available before the LINKMON process can initialize itself.
Each subsequent SERVERCLASS_SEND_ call in this processor causes the LINKMON process to
reattempt initialization; after the condition is corrected, the LINKMON process can complete
initialization.
Initialized and running
Cause. The LINKMON process is operational.
Effect. The LINKMON process is available for processing SERVERCLASS_SEND_ calls from requestors
in the processor.
