As previously discussed, static thresholds do not account for expected performance variation due to increased/decreased workloads encountered by the target, such as the workload encountered by a warehouse database target against which OLTP transactions are performed. Workloads can also change based on different time periods, such as weekday versus weekend, or day versus night. These types of workload variations present conditions where fixed static metric threshold values may cause monitoring issues, such as the generation of false and/or excessive metric alerts. Ultimately, your monitoring needs dictate how to best go about obtaining accurate metric thresholds.
