Any member can host an embedded JMX Manager, which provides a federated view of all MBeans for the VMware Tanzu GemFire cluster. The member can be configured to be a manager at startup or anytime during its life by invoking the appropriate API calls on the ManagementService.
You must have a JMX Manager started in your Tanzu GemFirecluster to use Tanzu GemFire management and monitoring tools such as gfsh and Tanzu GemFire Pulse.
To create MBeans, a Security Manager must be enabled. See Enable Security with Property Definitions for more information.
Note: Each node that acts as the JMX Manager has additional memory requirements depending on the number of resources that it is managing and monitoring. Being a JMX Manager can increase the memory footprint of any process, including locator processes. See Memory Requirements for Cached Data for more information on calculating memory overhead on your Tanzu GemFire processes.
