摘要： A two-pass technique for instrumenting an application is disclosed. One pass may be performed statically by analyzing the application and inserting probes while the application is not running. Another pass may be performed dynamically by analyzing data collected by the probes while the application runs to derive metrics for the probes. One or more metrics for each probe may be analyzed to determine whether to dynamically modify the probe. By dynamically modifying the probe, the application does not need to be shut down. Dynamically modifying the probe could include removing the probe from the application or moving the probe to another component (e.g., method) in the application, as examples. For example, the probe might be moved to a component that is either up or down the call graph from the component that the probe is presently in.

摘要： An agent object can invoke one or more methods of an application object using a helper object. The application object passes a reference to itself to the agent object. The agent object identifies a class loader of the application from the reference. The agent object obtains byte code of a helper class and uses the byte code of the helper class to creating a helper class loader. A parent of the helper class loader is set as the class loader of the application. The helper class loader is used to load the helper class and define an instance of the helper object. Using the helper object, the one or more methods of the application object are invoked by the agent using casting, without having a direct class loader connection with the class loader of the application.

摘要： Transaction-segregated metrics are obtained for component invocations of different transactions of an application. Corresponding tree data structures are maintained by an agent and a manager which describe sequences of invoked components of the different transactions. The start and end of each component are each represented by a node in each branch of the tree data structure. Each transaction is identified by matching a branch to a transaction trace. Gatherers are linked to one or more nodes to collect the transaction-segregated metrics. For example, metrics can be gathered separately for component invocations in different transactions. Metrics can also be gathered together for instances of different components in one or more transactions. A user interface includes a directed graph having vertices connected by edges. Edge portions are visually distinguished from one another based on the metrics of the gatherers. Each edge portion can be associated with one or more of the gatherers.

摘要： Techniques for analyzing software in which un-instrumented components can be discovered and conditionally instrumented during a runtime of the software. Initially, software such as an application can be configured with a baseline set of instrumented components such as methods. As the application runs, performance data gathered from the instrumentation may indicate that the performance of some methods is below expectations. To analyze this, any methods which are callable from a method at issue are discovered, such as by inspecting the byte code of loaded classes in a JAVA Virtual Machine (JVM). To limit and focus the diagnosis, the instrumentation which is added to the discovered components can be conditional, so that the instrumentation is executed only in a specified context. The context can involve, e.g., a specified sequence of components in which a discovered component is called, and/or transaction data in which a discovered component is called.

摘要： Efficiently identifying transactions processed by a software application, such as a server application is disclosed. In one embodiment, transactions are identified by applying a set of rules to communications between a client and server to determine whether certain patterns are in the communications. For example, the rules may look for some combination of parameters in the transactions. As a particular example, the rules may be used to look for parameters in HTTP requests. The rules are organized in a way that allows efficient processing. For example, the rules may be organized based on the frequency with which the parameters are expected to occur in the transactions and the frequency with which each transaction is expected to occur. The rules may be updated if the expected frequencies deviate from actual frequencies, such that the rules can be organized for more efficient processing.

摘要： Technology is disclosed herein for managing versions of an Agent associated with an application. Code for the Agent can be updated, and subsequently rolled back without being disruptive to the application. The technology includes running an Agent with an Application in a Java Virtual Machine and rolling back the Agent to use a previous version of code for the Agent while the Application and the Java Virtual Machine continue to run. The rolled back Agent with the Application in the Java Virtual Machine can then be run while the Application and the Java Virtual Machine continue to run.
