Abstract
Managing a computer system including automatically adjusting two separate component thresholds (a component threshold pair) based on a statistical model. Specifically, a first component threshold is modeled to predict violations of an SLO based on a violation of the first component threshold and a second, separate component threshold is modeled to predict a non-violation (compliance) of an SLO based on a non-violation of the second component threshold. Over time, the values of the component thresholds may change and one component threshold may be greater than the other component threshold at one time, and vice versa at another time. A component metric reading between the first and second component thresholds indicates that a prediction of an SLO violation or compliance is less certain, and a warning may be issued rather than an alert.
