Instrumenting the Policy Injection Application Block

The Policy Injection Application Block does not include any built-in instrumentation in this release. This may be a feature in subsequent releases, but developers, operators, and administrators can use the injection features inherent in the application block, and the handlers provided with it, to add instrumentation features that they may require.

For example, the Logging Application Block provides a wealth of features for capturing execution parameters and call duration, and writing logging information and messages to a range of other applications and formats such as Windows Event Log, Windows Management Instrumentation (WMI), application log files, message queue services, and more. Developers, operators, and administrators can use a Logging Handler to capture information on operation of the application block as it intercepts calls to target classes.

In addition, the Policy Injection Application Block includes the Performance Counter Handler that will capture information when the application block makes calls to target objects. This information can also provide insights into the operation of the Policy Injection Application Block.
