Workspace WebSphere Liberty
Created by Guest
Created on Aug 20, 2024

Provide the ability to suppress selected messages completely, simiar to "hideMessage" but causing messages to be completely suppresed.

It has been found that the writing of a very high volume of messages to the WebSphere Liberty messages.log has the ability to severely impact the performance of a server.  In this case, the z/OS Connect product running within a Liberty server was writing millions of GMOMW0005E messages to messages.log. The attempts to write all these messages to a file caused contention for the file, this in turn cause the pthread_yield function to be called. The pthread_yield processing involves setting a STIMER and as STIMER is native z/OS function,  zIIP eligible work had wait for the STIMER processing to run on CPs. This had a catastrophic impact on the performance of the system and it was very difficult to identify the root cause. 

The existing Liberty function "hideMessage" causes messages to be redirected from messages.log to trace.log, but that does not help in this scenario as it redirects the messages from messages.log to trace.log and the messages are still written to a file. 

While the problem was observed with z/OS Connect messages, any message that goes through the Liberty logging/tracing mechanism has the ability to trigger this problem. 

We're requesting an option which allows any messages reported via the Liberty tracing and logging mechanism to be completely suppressed. Ideally there would be configuration that would allow a number of the messages to be logged until a threashold is reached, so that any failures are not totally silent, but are not allowed to cause the performance problems.

    This has caused outages for my installation and the work around is to not log which has its own ramifications. We need more granular control over messages written for this critical infrastructure.

    I have another z/OS Connect customer case TS017188812, where the trace.log was also getting large after using the 'hideMessage' function.
