EJB Tier Analysis workspace

The workspace displays detailed information about application tier health for a selected WebSphere® application.

The application tier health is derived from the following performance statistics:
  • Calculated application request delays in EJB container or custom requests delays compared against corresponding thresholds assigned in application configuration.
  • Completion rates for application edge EJB requests.
  • Application server ORB thread pool utilization level.
  • PMI statistics for application EJB container transactions begin, commit, and rollback rates.

This workspace displays data provided by the Application Health Status attributes.

The predefined workspace contains:
  • Application Tier Analysis report, which shows the overall health status of the Application tier for a selected application. For monitoring agents running on z/OS®, region ID can be found in the ASID column.
  • Container Pool Usage bar chart, which displays the average number of concurrently active threads and the average number of free threads in the pool. This view displays data provided by the Thread Pools attributes.
  • Worst Application Tier Delays - Top 10 bar chart, which displays the top ten delayed requests in the application tier. This view displays data provided by the Request Analysis attributes.
  • Worst Application Tier Completion Rates - Top 10 bar chart, which displays the top ten worst requests in the application tier. This view displays data provided by the Request Analysis attributes.
  • Container Transactions bar chart, which displays the counts of global and local transactions that were started, committed, and undone during the interval. This view displays data provided by the Container Transactions attributes.
  • JVM Health - CPU Used % graph, which displays the percentage of the CPU used by the Java™ virtual machine (JVM) during the interval. This view displays data provided by the Application Server attributes.
  • JVM Health - Heap Used % graph, which displays the current heap usage for the monitored JVM. This view displays data provided by the Garbage Collection Analysis attributes.
  • JVM Health - GC Time % graph, which displays the percentage of real time that the garbage collector was active during the interval. This view displays data provided by the Garbage Collection Analysis attributes.
