How fast should the app be? Under what circumstances should these performance levels be maintained? What will be acceptable from the user`s point of view? If you define service level agreements (SLAs) for measures evaluated on a timeline, monitors the SLA state within specified time intervals within that period. The frequency of time intervals is called the follow-up period. A service level agreement (SLA) is a contract or obligation between a service provider and its customers, which defines the service standards for which the provider is responsible. Agreements may be legally binding or, in the case of website or application SLAs, a standard agreed within an organization for their users or customers. Implementing a performance SLA reinforces your company`s commitment to the user experience and ensures a (hopefully) satisfied customer and many visits. This question explains how service level agreements (SLAs) are defined. SLAs measure performance test objectives over time intervals during a test run or throughout a performance test. Performance testers set SLAs-level agreements to ensure that applications meet certain performance markers. An SLA reads pretty much like this: the controller is, as the name suggests, a program for “checking” the global load test. . . .
