With changing business requirements and performance goals, monitoring performance of your environment using predefined static thresholds might not be a feasible solution. The static values are calculated through trial and error, which is often time-consuming. These values become out of context in the long-term and the settings must be re-evaluated to ensure compliance.
By automating the threshold setting you gain better visibility into your environment and performance trend patterns. Dynamic thresholds adapt to your environment and proactively sends alerts before the performance bottleneck occurs.
