A computer-implemented method for triggering a software rejuvenation system or method in a computer-system including a plurality of replicates includes receiving a request for resources at a first replicate, determining an estimated response time to the request for resources, and determining that the estimated response time is greater than a first threshold. The method further includes determining that a number of estimated response times greater than the first threshold is greater than or equal to a second threshold, wherein the second threshold of the first replicate is different than a second threshold of a second replicate of the computer-system, and triggering the software rejuvenation system or method for the first replicate.
