[Version 5.0.1 and later]Setting performance monitoring levels

Before you begin

The monitoring settings determine which counters are enabled. Changes made to the settings from Tivoli Performance Viewer affect all applications that use the Performance Monitoring Infrastructure (PMI) data.

Why and when to perform this task

To view monitoring settings:

Steps for this task

  1. Choose the Data Collection icon on the Resource Selection panel.
    This selection provides two options on the Counter Selection panel. Choose the Current Activity option to view and change monitoring settings. Alternatively, use File> Current Activity to view the monitoring settings.
  2. Set monitoring levels by choosing one of the following options:

    • None: Provides no data collection
    • Standard: Enables data collection for all modules with monitoring level set to high
    • Custom: Allows customized settings for each module

    These options apply to an entire application server.
  3. (Optional) Fine tune the monitoring level settings.
    1. Click Specify.
      This sets the monitoring level to custom.
    2. Select a monitoring level.
      For each resource, choose a monitoring level of None, Low, Medium, High or Maximum. The dial icon will change to represent this level. Note: The instrumentation level is set recursively to all elements below the selected resource. You can override this by setting the levels for children AFTER setting their parents.
  4. Click OK.
  5. Click Apply.

Results

If the instrumentation level excludes a counter, that counter does not appear in the tables and charts of the performance viewer. For example, when the instrumentation level is set to low, the thread pool size is not displayed because that counter requires a level of high.

Note that monitoring levels can also be set through the administrative console. See Enabling performance monitoring services in the application server through the administrative console for more information.
