Detecting correlation between server resources for system management

作者:

Highlights:

• Evidence of correlation between resource measures facilitates system management.

• Capacity planning, forecasting, anomaly detection benefit of this evidence.

• Existing models fail in finding correlation when resource data variability is too high.

• We propose a model that captures correlation independently of datasets variability.

• The proposed model improves accuracy and robustness of existing algorithms.
