JARM Runtime Views

Request Summary

The Request Summary tab displays accumulated data since system start or data reset. The most important counters are: Average response time of a request and Number of requests.

If the system is permanently under load, you must also pay attention to the Requests per second counter. The Average outbound data counter gives an impression of the transferred data amounts. In combination with the Requests providing outbound data, you may have an indicator of the typical system load.

Request Overview

The Request Overview tab shows the most important requests and components selected by different criteria, such as the response time or amount of transferred data. The response time shows the elapsed time required. The slowest response gives an indication about where performance analysis is necessary.

Choose one of the requests to display detailed information in the pane below. The net time shows the slowest components ("net time" means the time a thread stays in a component, without the time left in sub components).

The levels show how deep a component is nested (0 = the highest level).

Component Overview

The Component Overview tab shows the data collected for each component in a condensed way. The data can be sorted by average gross time, outbound data, average net time, or the number of calls.

User Overview

The User Overview tab shows the username with average response time, number of requests and time of the first and the last request.

Thread Overview

The Thread Overview  tab displays all the threads that are still alive and have been used by applications instrumented with JARM.

This tab also shows the elapsed time per thread used by JARM requests and the components active time.

The Action column shows the current action in a component (optional). If the same action or the same component is shown in several threads it may indicate lock problems in this area.
