Petals ESB Hazelcast Registry is the default registry implementation, based on the [Petals Registry Overlay]

{anchor:Configuration}

The Petals ESB Hazelcast Registry uses the following loggers to trace its execution:
* *{{Petals.System.Registry}}*: associated to the Petals ESB internal component associated to the registry client,
* *{{com.hazelcast}}*: the low-level client part based on Hazelcast stack.

As the Petals ESB Hazelcast Registry is provided as default into the ZIP and Debian archives of Petals ESB, its logging configuration is already configured as following:
{code}
Petals.System.Registry.level=INFO
com.hazelcast.level=WARNING
{code}
