Define Thresholds in Enterprise Manager

There are monitoring situations in which different workloads for a target occur at regular (expected) intervals. Under these conditions, a static alert threshold would prove to be inaccurate. For example, the accurate alert thresholds for a database performing Online Transaction Process (OLTP) during the day and batch processing at night would be different. Similarly, database workloads can change based purely on different time periods, such as weekday versus weekend. In both these situations, fixed, static values for thresholds might result in false alert reporting.

Advanced Thresholds allow you to define and manage alert thresholds that are either adaptive (self-adjusting) or time-based (static).

Adaptive Thresholds are thresholds based on statistical calculations from the target's observed behavior (metrics).

Time-based Thresholds are user-defined threshold values to be used at different times of the day/week to account for changing target workloads.
