Web Applications workspace

This workspace displays data provided by the Web Applications attributes.

This workspace displays information about the web applications running in J2EE application servers.

Notes:
  • The Web Applications 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 processor usage, the monitoring agent provides on-demand sampling by default. To activate PMI monitoring, you must 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:
  • Worse Response Times bar chart, which shows the worst servlet response times (in milliseconds) during the interval
  • Most Popular Web Applications bar chart, which shows the servlet exception and request rates (in events per second)
  • Worse Error Rates bar chart, which shows the worst servlet error rates during the interval
  • Web Applications report, which displays aggregated performance data for each web application, about all servlets and JSPs deployed to that web application, including response and error rates, and response times.

Accessing the Web Applications workspace

To access this workspace, complete the following steps:
  1. Within the Navigator, expand Windows Systems, Linux® Systems, z/OS® Systems, or UNIX Systems, as appropriate for the node you are monitoring.
  2. Within the node list, expand the entry that corresponds to the node that you want to select.
  3. Within that node list of monitored applications, expand the list of WebSphere agent.
  4. Within the list of available agents, expand the WebSphere Application Server of your choice.
  5. Within that server list of available WebSphere Application Server workspaces, click the Web Applications entry.

Accessing the managing server visualization engine from the Web Applications workspace

In the Tivoli® Enterprise Portal access the WebSphere Agent workspace. You can use the Diagnostic Server Activity Display link to access the managing server visualization engine.
  1. In the Web Applications window, right-click the choose link icon Choose link - link in a chain then click Diagnostic Server Activity Display.
  2. If this is your first time to access the managing server visualization agent during a session, you see a Welcome to the Application Monitor page.
  3. Depending on the user setup configuration in your environment you might have to type your managing server visualization engine User Name and Password. If you do, you need to log in only once per session using your User Name and Password.
  4. Click OK to display the Server Activity Display page in the managing server Visualization engine. You can use link to diagnose application problems, for example, slow transactions or high response times.
  5. The results in this page relate directly to the context from where you launched the link in the Tivoli Enterprise Portal. For more information about using the Server Activity Display page and additional features, refer to the Composite Application Manager help within the managing server visualization agent Interface.
  6. To return to the previous workspace in the Tivoli Enterprise Portal interface at any time choose from the following options:
    • From the Tivoli Enterprise Portal desktop client, including WebStart, click the back arrow on the Portal toolbar.
    • From the Tivoli Enterprise Portal browser client, click the browser back arrow.
