Out-of-the-box thresholds are set to use hourly, daily, weekly, or all baselines. These settings work well in majority of the cases, but it might be more appropriate to use one specific baseline type in order to catch the exceptional behavior.
The Autobaseline analysis engine automatically detects abnormalities in any monitor instance attribute and determines the best baseline to be used depending on the behavior of the monitor instance.
By default, the autobaseline feature is enabled for new installation, and out-of-the-box thresholds have the autobaseline option set.
When upgrading the product, the autobaseline feature is enabled, but you must manually set a threshold with the autobaseline option.
