IBM Tivoli Composite Application Manager for Application Diagnostics, Version 7.1.0.1
Sessions workspace
This workspace displays information about servlet sessions.
A session is a series of requests to a servlet, originating from the same user at the same browser. Applications running in a Web container can use these sessions to keep track of individual users. This workspace displays data provided by the Servlet Sessions attributes.
- This workspace reports blanks for resource data on the first invocation if PMI data collection is configured for on-demand sampling (that is, if your site set configuration value Resource Data Collection Method to On Demand) or if you have not yet run applications that generate PMI resource data. To report resource data in this workspace after installing and configuring the data collector, use the WebSphere administrative console to set the appropriate PMI instrumentation level.
- Because of high overhead, the Tivoli Enterprise Monitoring Agent provides on demand sampling by default. To activate PMI monitoring, first select this workspace and then select it again later. Each time you select the workspace, it displays the data collected during the interval between selections.
The predefined workspace contains the following items:
- Most Active Sessions bar chart, which shows the most frequently referenced servlet sessions for each listed Web application
- Largest Total Session Object Sizes bar chart, which shows the total session object sizes (in bytes) and the associated Web applications
- Servlet Sessions report
Shows usage data about the servlet sessions, including the rates as which sessions are created and destroyed and their read and write times
