In [45], the authors proposed an alternative approach, where the customer defines the SLA and the IPs set the resource utilisation thresholds.
Some of the control theory proposals react to monitored metrics such as CPU utilisation thresholds and workload throughput [50], but most of the proposals surveyed use a proactive mechanism to forecast the future workloads, typically using time series.
Successful endurance performance is highly correlated with an athlete's for the event duration (fractional utilisation or lactate threshold) 33 34 and exercising with relatively low energy expenditure (good economy).
To adapt power configuration, reactive approaches [56, 69] use a low threshold for CPU utilisation to switch nodes to sleep state.
Reactive approaches invoke adaptation when a monitored metric, e.g. CPU utilisation, reaches a specific threshold.
To overcome the gap between the need for treatment and evidence-based treatment availability and utilisation, cost-effective low-threshold interventions are strongly needed to be accessible to as many people as possible.
To derive threshold distances for estimating utilisation, the proportion of clients using retail outlets for a fever in a particular locality was derived from a previous household survey [17].
Danish hospitals have a high number of beds available compared to hospitals in KP, and supply is a powerful determinant of utilisation, which also could lower admission thresholds [ 25, 30].
Following a heuristic approach, the authors in [53] assign application tiers to nodes, preserving CPU utilisation in each node below a 60%% threshold.
In this study the presence of a discontinuity in utilisation and out-of-pocket health expenditure at the eligibility threshold is tested using parametric regression analysis [12, 13].
