Scheduling maintenance in a computer system

A computer system comprising:

• one or more processors;
• and
• one or more storage devices storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• monitoring performance metrics of the computer system, the performance metrics being associated with one or more predefined system performance requirements, thus obtaining historic performance metric data,
• predicting from the historic performance metric data, for a plurality of future time frames, a quantitative compliance metric indicating compliance with the one or more predefined system performance requirements,
• estimating an impact of a proposed maintenance activity on the quantitative compliance metric for the plurality of future time frames,
• calculating, for each future time frame, a risk factor indicative of a likelihood of violation of each of the one or more predefined system performance requirements, the risk factor being based on the predicted quantitative compliance metric and the estimated impact of the proposed maintenance activity,
• computing, for each future time frame, a combined risk factor from the risk factor associated with the one or more predefined system performance requirements,
• obtaining a selected time frame for performing the maintenance activity based on the combined risk factors, and
• initiating the maintenance activity in the selected time frame.

One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by a computing system, cause the computing system to perform operations comprising:

• monitoring performance metrics of the computer system, the performance metrics being associated with one or more predefined system performance requirements, thus obtaining historic performance metric data,
• predicting from the historic performance metric data, for a plurality of future time frames, a quantitative compliance metric indicating compliance with the one or more predefined system performance requirements,
• estimating an impact of a proposed maintenance activity on the quantitative compliance metric for the plurality of future time frames,
• calculating, for each future time frame, a risk factor indicative of a likelihood of violation of each of the one or more predefined system performance requirements, the risk factor being based on the predicted quantitative compliance metric and the estimated impact of the proposed maintenance activity,
• computing, for each future time frame, a combined risk factor from the risk factor associated with the one or more predefined system performance requirements,
• obtaining a selected time frame for performing the maintenance activity based on the combined risk factors, and
• initiating the maintenance activity in the selected time frame.
