Embodiments include methods, and computing systems, and computer program products for automatic discovery and classification of Java virtual machines running on a logical partition of a computing system. Aspects include: examining, via a service request block (SRB) routine, each of address spaces to identify one or more address spaces eligible to operate a Java virtual machine, retrieve, by a Java virtual machine management system via a CSVINFO macro call to each of address space control blocks on the logical partition of the computing system, in a predetermined interval, each of the of Java virtual machines corresponds to one of the address spaces, discovering, through CSVINFO retrieved, one or more Java virtual machines running on the logical partition of the computing system, and classifying, through Content Directory Entries examined using the CSVINFO macro, the one or more Java virtual machines discovered.

Embodiments include methods, and computing systems, and computer program products for collecting performance metrics from Java virtual machines. Aspects include: setting up a virtual storage structure of a collector on a computing system for collecting performance metrics data from one or more Java virtual machines, pushing, at each of Java virtual machines through a corresponding performance monitoring Java agent, performance metrics data collected by the Java virtual machine to the virtual storage structure of collector, pulling, at a performance monitoring system through a collector API, the performance metrics data collected by the plurality of Java virtual machines from the virtual storage structure of the collector, analyzing the performance metrics data pulled from the virtual storage structure of the collector by the performance monitoring system, and generating, at the performance monitoring system, a performance alert when the performance metrics data analyzed indicates one or more system abnormalities.
