Performance management of all Java Virtual Machines on z/OS

IBM® OMEGAMON® for JVM on z/OS provides resource level monitoring of all Java Virtual Machines on z/OS enabling visibility and insight into Java performance across subsystems. Using this tool, you can quickly identify Java related performance issues allowing corrective action to be taken before they cause major problems.

OMEGAMON for JVM on z/OS provides:

  • Auto-discovery all online JVMs allows a clear understanding of the amount of Java workload currently executing and where it is running in a single screen.
  • Detailed real-time and historical reports on Java key performance indicator resources such as Garbage Collection, Thread Status and Lock Utilization to show visibility of Java application performance.
  • Help to reduce MLC through monitoring of CPU utilization including identification of zIIP offload levels.
  • Integration with OMEGAMON monitoring family within enhanced 3270 user interface and Tivoli Enterprise Portal providing a single user interface choice for full mainframe monitoring.
  • Resource monitoring of z/OS Connect Enterprise Edition enabling visibility into performance and throughput levels.

Auto-discovery all online JVMs

  • No application configuration required to discover and identify all address spaces running a JVM.
  • Automatically identifies the subsystem type, Java version and Java home location.
  • Enables users to view all active JVMs from any subsystem or batch application within a single screen.
  • Minimal configuration required to enable full monitoring of JVM.

Detailed real-time and historical reports on Java key performance indicator resources

  • Identifies problematic thread and locking issues and suboptimal garbage collection performance.
  • Capture deadlocks and bottlenecks and identifies the application within the JVM at the root cause.
  • View resource metrics over time to identify memory leaks before a server error results.
  • Drill down into detailed JVM environment information to understand the context the application is running in.

Help to reduce MLC through monitoring of CPU utilization

  • Displays the overall CPU utilization and amount of zIIP offload occurring for the monitored address space.
  • Shows the amount of potential zIIP offload that was not realized to processor capacity limits.
  • Enables user to understand their Java offload limits and maximize the benefits of offloading.

Integration with OMEGAMON monitoring family within enhanced 3270 user interface and Tivoli Enterprise Portal

  • Simplifies monitoring and management with a single-view of the mainframe and subsystems.
  • Allows you to move between different z/OS components to provide a common look and feel of command and control conditions.
  • Provides monitoring by exception via pre-defined and user customizable alerts that trigger when problem situations occur.
  • Enable users to be alerted to problems within JVM performance, isolate the issue, and identify the root cause of the problem.

Resource monitoring of z/OS Connect Enterprise Edition

  • Auto-identification of JVMs running z/OS Connect Enterprise Edition.
  • Provides enhanced details of the services and APIs available through this gateway including request and response times.
  • Provides monitoring by exception via pre-defined and user customizable alerts that trigger when problem situations occur.
  • Enables identification of slowest performing services to aid bottleneck analysis.
  • Allows users to understand the throughput levels of workloads originating outside of z/OS at any time
