One or more non-transitory machine-readable media (406, 410) storing instructions which, when executed by one or more processors, cause the one or more processors to perform the following operations: based at least on a plurality of attributes associated with a plurality of applications of one or more system-selected remedial actions to one or more problematic system behaviors in a database system: determining a first predicted effectiveness of one or more future applications of a first remedial action to a particular problematic system behavior in the database system as of one or more future times; determining that the first predicted effectiveness of the one or more future applications of the first remedial action is positive but does not satisfy one or more performance criteria, wherein determining that the predicted effectiveness of the one or more future applications of the first remedial action is positive but does not satisfy the one or more performance criteria comprises one or more of: predicting whether (or not) a series of applications of the first remedial action to the particular problematic system behavior is effective but decreasing in effectiveness, or predicting whether (or not) that after the one or more future applications of the first remedial action, the problematic system behavior will return within a threshold amount of time; responsive to determining that the first predicted effectiveness of the one or more future applications of the first remedial action is positive but does not satisfy the one or more performance criteria: generating a notification corresponding to the first predicted effectiveness of the one or more future applications of the first remedial action not satisfying the one or more performance criteria; applying the first remedial action to the particular problematic system behavior despite already determining that the first predicted effectiveness of the one or more future applications of the first remedial action does not satisfy the one or more performance criteria. based at least on a plurality of attributes associated with a plurality of applications of one or more system-selected remedial actions to one or more problematic system behaviors in a database system: determining a first predicted effectiveness of one or more future applications of a first remedial action to a particular problematic system behavior in the database system as of one or more future times; determining that the first predicted effectiveness of the one or more future applications of the first remedial action is positive but does not satisfy one or more performance criteria, wherein determining that the predicted effectiveness of the one or more future applications of the first remedial action is positive but does not satisfy the one or more performance criteria comprises one or more of: predicting whether (or not) a series of applications of the first remedial action to the particular problematic system behavior is effective but decreasing in effectiveness, or predicting whether (or not) that after the one or more future applications of the first remedial action, the problematic system behavior will return within a threshold amount of time; responsive to determining that the first predicted effectiveness of the one or more future applications of the first remedial action is positive but does not satisfy the one or more performance criteria: generating a notification corresponding to the first predicted effectiveness of the one or more future applications of the first remedial action not satisfying the one or more performance criteria; applying the first remedial action to the particular problematic system behavior despite already determining that the first predicted effectiveness of the one or more future applications of the first remedial action does not satisfy the one or more performance criteria. generating a notification corresponding to the first predicted effectiveness of the one or more future applications of the first remedial action not satisfying the one or more performance criteria; applying the first remedial action to the particular problematic system behavior despite already determining that the first predicted effectiveness of the one or more future applications of the first remedial action does not satisfy the one or more performance criteria.
