Configure and View Baselines

A baseline deviation is the standard deviation from a baseline at a point in time, represented as an integer value. You can set health rule conditions based on baseline deviations. For example, you can configure a warning condition as two standard deviations from the baseline and a critical condition as four standard deviations from the baseline.

To configure baselines:

  1. Navigate to Configuration > Baselines.
    • All available baselines display in the list.
    • The daily trend is the default baseline. This is the baseline used by health rules if another baseline is not specified during health rule creation.
  2. Click Set as Default to choose another baseline in the baseline list as default.
    Warning: Changing the default baseline changes the actual baseline for all existing health rules that rely on this default and do not specify another baseline. Be watchful of your existing baselines and health rule definitions before you select this option.
  3. Select the trend type to use.
  4. Set the trend time period and the trend. The base time period is available in these two ranges:
    • Fixedtime range: from some specific date and time to a second specific date and time. For example, if you have a release cycle at a specific time you might limit your data collection to that specific time.
    • Rollingtime range: in which the most recentXnumber of days is used. This is the more common choice.
