APM - application performance management
Tools and processes responsible for monitoring and managing the performance and availability of software applications. Application performance management (APM) tools alert IT staff to disruptions in availability and/or quality to end users when accessing mission-critical applications. Applications monitored by APM tools can include traditional non-connected applications, Web-enabled applications, streaming apps and cloud applications.
In addition to real-time monitoring, many application performance management tools can also prevent problems from occurring by detecting early warning signs of issues and can also help automatically resolve some performance and quality issues.
