Abstract: A system and method for facilitating analysis and modification of a computer program. A directed graph is generated from an intermediate language representation of a computer program function, with a node representing each instruction. Meta-edges or meta-nodes are inserted into the directed graph to facilitate location of instruction nodes. One type of meta-edge is a back edge that identifies branch instruction nodes. Some meta-nodes may identify instructions of a specific type. Some meta-nodes may identify exception blocks and corresponding handlers. Analysis of a program function may include insertion of new instructions prior to execution of the function.

Abstract: A system and method for generating a computer program call graph. A profiler may insert probes into a debuggee computer program, the probes generating call trace events. Checkpoints may be performed during execution of the debuggee program, so that a snapshot of the call stack is performed. Call trace events and checkpoint snapshots are logged and serialized. Logged call trace events and checkpoints may be retrieved and used in combination to generate a call graph and a shadow stack. Mechanisms facilitate combining the different sources of debuggee program information and determining whether the call graph and shadow stack are determinate or indeterminate at any time. The mechanisms may provide for improved accuracy of generated call graphs.

Abstract: Systems and methods for automated monitoring and management of distributed applications, client/server databases, networks and systems across heterogeneous environments. Distributed, automated intelligent monitoring agents use embedded sensing technology which is knowledgeable of application protocols, to monitor continuously the network environment in real time. To this end, the monitoring agent can be located on each client and server in the network. The monitoring agent can couple to the communications stack for monitoring the data that is being passed between the client and the network, of a server in the network. The data can be collected and employed for trouble shooting trend analysis, resource planning, security auditing, and accounting as well as other applications. Also included is a controller for remotely coordinating the data gathering process from the various clients and servers.
