Specified by:

registerSupplier in interface ExecutorServiceSupplierObserver

Parameters:

supplier - the executor service supplier registering with the observer

supplierIndex - unique index across suppliers with the same name

supplierCategory - supplier category for this supplier

Returns:

the SupplierObserverContext for the supplier

registerSupplier

Description copied from interface: ExecutorServiceSupplierObserver

Makes a supplier known to the observer and returns a supplier context for the supplier to use for future interactions with the observer, using the ExecutorServiceSupplierObserver.MethodInvocation abstraction for invoking methods to obtain metric values.

Specified by:

registerSupplier in interface ExecutorServiceSupplierObserver

Parameters:

supplier - the executor service supplier registering with the observer

supplierIndex - unique index across suppliers with the same name

supplierCategory - the category of supplier registering (e.g., scheduled, server, thread-pool)

methodInvocations - method invocation information for retrieving interesting information from the supplier's executor services

Returns:

the SupplierObserverContext for the supplier
