Configuring the Diagnostic Service
The Diagnostic Service provides more visibility into and control of the runtime performance of
a server and its applications, allowing you to diagnose and isolate faults as they occur.
This chapter contains the following sections:
■ “What is the Diagnostic Framework?” on page 141
■ “Diagnostic Service Framework” on page 141
What is the Diagnostic Framework?
The Application Server Diagnostic Framework is a monitoring framework that defines and
implements a set of services that run within the application server standard life cycle. With the
Diagnostic Service, you can define, create, collect, and access diagnostic data generated by a
running server and the applications it deploys.
Diagnostic Service Framework
The diagnostic service reports configuration details for the application server instances. It is
useful for diagnosing application server problems such as exceptions, performance issues, and
other unexpected results. From within the Admin Console Diagnostic Service you can:
■ Compute Checksum: Collects checksum for selective Application Server binary files under
appserver_install_dir/ lib , appserver_install_dir/etc and
appserver_install_dir/bin directory
■ Verify Configuration: Captures configuration files such as, domain.xml, server.policy.
■ Capture Install Log: Installation specific details such as Application Server version number
or patch ID and contents of log file generated at the time of installation. Absolute path for
installation directory is used to determine which Installer log file is collected if there are
multiple installations on the same machine. The contents of config/asenv.conf is copied
from the installation folder for DAS as well as node agents.
