Web Tier Analysis workspace

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

This workspace displays detailed information about the client tier health for a selected WebSphere® application.

The client tier health indicator is derived from the following performance statistics:
  • Calculated application request delays inside Servlet/JSP or Portal container compared against corresponding thresholds assigned in application configuration.
  • Completion rates for edge Servlet/JSP and Portal application requests.
  • Application server WebContainer thread pool utilization level.
  • PMI statistics for HTTP session counts by application.
The predefined workspace contains:
  • Web Tier Analysis report, which shows the overall health status of application execution in web or portal containers. For monitoring agents running on z/OS®, region ID can be found in the ASID column.
  • Web Contain bar chart, which displays the current utilization level of the web Container thread pool. This view displays data provided by the Thread Pools attributes
  • HTTP Sessions - Average bar chart, which displays the average number of concurrently active and live HTTP session numbers for the selected application during the interval. This view displays data provided by the Servlet Sessions attributes.
  • Worst Web Tier Delays bar chart, which displays the top 10 requests with biggest delays (threshold violations) in the client tier. This view displays data provided by the Request Analysis attributes.
  • Worst Web Tier Completion Rates bar chart, which displays the top 10 Servlet/JSP/Portal edge requests with the worst completion rates. This view displays data provided by the Request Analysis attributes.
  • JVM Health - CPU Used % graph, which displays the percentage of the host 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.
