Hybrid Connect provides a means of registering installed middleware and tracking its use. IBM middleware products call in to an IBM Bluemix service periodically to report registration and usage information. With the WebSphere Liberty November/December 2016 beta, available on November 18, the IBM Hybrid Connect capability is extended to Liberty. Liberty servers that have been configured to use Hybrid Connect can register with the service and periodically report usage metrics.
Each Liberty server instance may be configured to use IBM Hybrid Connect in just a few steps. You will need a Bluemix account. Using the Bluemix dashboard, you create an instance of the Hybrid Connect service. You then bind that service to each server instance using several scriptable commands. Specific steps are documented here.
Once these Liberty server instances are registered, the management console for the service, which is accessed through the Bluemix dashboard, provides a centralized view of all registered Liberty servers, whether they reside on premises or in the cloud. Descriptive information about the running server is provided, including its location, middleware product version, and installed APARs. A list of usage metrics is shown. For Liberty, these include the number of virtual cores on which each server is running, the CPU consumption, the number of web requests handled, and the amount of memory used.
This summary screen shows installed instances:
One can then drill down on an instance to find out what resources are being used, according to each of the available metrics:
With this information, an IT administrator or capacity planner can determine which servers need a software update, which are provisioned with appropriate resources, and which are becoming busy so that additional growth is needed. This facilitates cost effective allocation and planning of resources and licenses.
