In the fields of information technology and systems management, application performance management (APM) is the monitoring and management of the performance and availability of software applications. APM strives to detect and diagnose complex application performance problems to maintain an expected level of service .
In IT operations, software performance management is the subset of tools and processes in IT Operations which deals with the collection, monitoring, and analysis of performance metrics. These metrics can indicate to IT staff whether a system component is up and running (available), or that the component is behaving in an abnormal way that would ...
This leads to new challenges in today's development and monitoring tools to provide application developers, system- and application administrators with the information they need. Within distributed applications it is not easy to estimate if the application performs well. The following issues help in the evaluation of distributed applications:
For capacity management, performance engineering focuses on ensuring that the systems will remain within performance compliance. This means executing trend analysis on historical monitoring generated data, such that the future time of non compliance is predictable. For example, if a system is showing a trend of slowing transaction processing ...
Arm MAP, a performance profiler supporting Linux platforms.; AppDynamics, an application performance management solution [buzzword] for C/C++ applications via SDK.; AQtime Pro, a performance profiler and memory allocation debugger that can be integrated into Microsoft Visual Studio, and Embarcadero RAD Studio, or can run as a stand-alone application.
Software performance analysis – techniques to monitor code performance, including instrumentation. Hardware performance counter; DTrace – A comprehensive dynamic tracing framework for troubleshooting kernel and application problems on production systems in real time, implemented in Solaris, macOS, FreeBSD, and many other platforms and products.
Systems management refers to enterprise-wide administration of distributed systems including (and commonly in practice) computer systems. [citation needed] Systems management is strongly influenced by network management initiatives in telecommunications. The application performance management (APM) technologies are now a subset of Systems ...
Traditional SPE activities support Dev teams to meet non-functional requirements such as response times or scalability. In doing so, performance goals and metrics can be defined and measured through load testing. [1] [3] A method to achieve performance goals at an early stage of development are performance models. They can be created using ...
