Described herein are systems and methods for collecting and surfacing metrics with respect to their classification; and the use of the metrics by a workload manager and other application monitoring tools to provide quality-of-service and workload management. Each request is classified, either by the application server or another process. A request classification identifier (RCID) is associated with each request, and thereafter flows with that request as it is being processed. The RCID value is used by data collectors at various points in the system to aggregate the metrics, and a workload manager collects the metrics. The collected metrics are then processed by a rules engine at the workload manager, which analyzes the metrics and generates adjustment recommendations to provide quality-of-service and workload management.

Described herein are systems and methods for providing diagnostic information between an application server (e.g., a WebLogic server), and a virtual machine (VM) (e.g., a JRockit VM). In accordance with an embodiment, the system includes a diagnostic monitoring component adapted to obtain diagnostic data indicative of all available data on an application server, including diagnostic information from one or more application server components running on the application server, obtain diagnostic data from the virtual machine, and persists the diagnostic data obtained from the application server and the virtual machine into a diagnostic data image file. The system further includes a console that provides access to the diagnostic data persisted into the diagnostic image file.

Disclosed herein is a system and method for dynamically redefining class files in a Java-based development environment. The existing development cycle in Java generally requires developers to edit, build, and deploy before they can test changes to the code. This process can be quite time consuming. There is a need for dynamically redefining and testing class files in a development environment without a significant time delay or loss of data. In one embodiment, when a developer modifies the class definition a ClassFileTransformer function is used to maintain the original shape of a redefinable class, i.e. its declared fields and methods, without affecting the redefined class' behavior or appearance to outside code.

Metadata can be used for determining or selecting debug points to activate for server software. The metadata can be used for selecting or logically grouping the debug point without requiring the selecting of debug points based upon package boundaries. The metadata can be used by the system to produce a select set of the debug activation information. This debug activation information can be used by a management unit to activate debug points in the server software.

A system and method for synthesizing custom metric attributes from available attributes. The system includes an application server that exposes available metric attributes of a MBean. A network console displays for selection the metric attributes of the MBean on a navigation tree and a view panel is located on the network management console where the metric attributes are dragged. The console and view panel allow network administrators to review monitoring data collected exposed by the application server. Custom attributes are created by combining attributes made available by the application server and can be combined to synthesize a custom expression that can be made available to other managed servers on the application server.

A system and method for sharing security information across multiple SNMP Agents running within a domain, including features such as dynamically extending SNMP MIB to expose customer MBeans with SNMP. The system includes a managed server instance of an application that hosts an SNMP agent. An agent or sub-agent is registered to the SNMP Agent on each managed server and there is a management information base which describes different management attributes that the application server exposes. A network-manager hosts a SNMP manager that communicates with the SNMP Agents. A non-application server specific MBean exposes a set of attributes about the application to the sub-agent and hosts the non-application server specific MBean in a dynamic MIB. The set of attributes are communicated through SNMP by the SNMP Agent to SNMP manager, to extend the SNMP MIB dynamically, and allow the non-application server specific MBean to be exposed through SNMP.

Code can be injected into a compiled application through the use of probes comprised of instrumentation code. Probes can be implemented in a custom high level language that hides low level instruction details. A directive file contains instructions on injecting a probe into a compiled application. An instrumentation engine reads these instructions and injects the probe into the compiled application at the appropriate injection points. Multiple probes can be used, and can be stored in a probe library. Each probe can inject code into the application at, for example, a package, class, method, or line of the compiled application. Calls can also be made to external runtime libraries.

Flexible and extensible java bytecode instrumentation system

Upon an event, diagnostic information about the state of server software can be compiled. The diagnostic information can include information concerning the JDBC subsystem. A timer can be used to inhibit a compilation of a new diagnostic image if the old diagnostic image was recently compiled.

An instrumentation service is described that uses dye injection and filtering in a Session Initiation Protocol (SIP) application server environment. The instrumentation service can provide a flexible mechanism for selectively adding diagnostic code to the SIP application server and the various applications running on it. It can allow flexible selection of locations in the server and application code, at which instrumentation code can be added. The process of adding diagnostic code can be deferred to the time of running the server at the deployment site. The instrumentation service further allows flexible selection of diagnostic actions, which can be executed at selected locations. In various embodiments, the execution of diagnostic code can be dynamically enabled or disabled while the server is running. Also, the behavior of diagnostic code executed at such locations can be dynamically changed while the server is running.
