New jar file in OWD Community Edition 4.0 Sprint 5 (perf4j)

[walle]

Hi,
I have downloaded the latest OpenWorkdesk Community Edition 4.0 Sprint 5 and I have seen that you have added a new jar file: perf4j-0.9.16 into ow_core lib path.
I find out that this jar files is used for performance logging and monitoring framework for Java (Perf4J).
How can I configure this monitoring framework?
Is it also available for custom implementations, or only for the core components?

best regards,
Walle

Hi,

that lib is needed from version 4.0 on by the OpenWorkdesk deployment,
which allow to activate now a performance logging.

Check the exmaples in the provided log4.properties files, you should find something similar to following

# perf4j
## To turn off this logger, set the level to "OFF". To activate logger, use level "INFO".
log4j.category.org.perf4j.TimingLogger=OFF

The resulting log can be afterwards parsed through tools and provide an overview of the time consumed by components of which are running.
