The present disclosure is related to predicting application response lime based on metrics. An example machine-readable medium may store instructions executable by a processing resource to determine a particular response time and an average response time of an application based on a plurality of relevant performance metrics associated with the application during a first period of time, classify the particular response time into a group based on the average response time, and determine a relationship between the plurality of relevant performance metrics and the particular response time of the application. The example machine-readable medium may further store instructions executable by the processing resource to determine whether a response time of the application is likely to change sufficiently to change the classification to a different group during a second period of time based on the relationship.
Please help me write a proper abstract based on the patent claims. CLAIM: 1.
