Adaptive Thresholds

Performance monitoring is typically based on comparing measurable values against a set of threshold values. In theory, the IT operations team determines what the thresholds for warnings and alerts should be and sets them. In practice, they usually have no idea what the appropriate values should be. For example, "response time" usually varies based on the time of day and day of week. At night, when the network load is negligible, response times would likely be minimal, too.
