Specifying an Exceeded Standard Deviations component

These steps describe how to build an Exceeded Standard Deviation (ESD) component.

Procedure

  1. Name the component.
  2. In the Source panel, do the following.
    1. Define the Standard Deviation value that sets the number of standard deviations above (or below) the historical value for whatever time period you are looking at.

      The value can be a constant value or it can be custom to the customer based on a lookup value from a datasource or on a calculated math value.

      The value can be any of the following.

      • Positive, to track an increase
      • Negative, to track a decrease
      • A constant value
      • A lookup value from a profile data source
      • If the data dependency allows it, a value from a transaction data source.
      • A calculated math value
    2. Select the data source by type and name, and identify the field on which to do the trending.
  3. In the Spike Period Value panel, enter the ESD period you want to track and the function to apply to the data within that period.
  4. In the Historical Value for Period panel, enter the ESD period you want to use for comparison.
  5. Optionally, set values in the Advanced Configuration panel.

    Advanced configuration settings can further refine the criteria used to evaluate the trend, and can help to ensure that data has been tracked long enough, or that there are enough data points, to be statistically significant.

  6. Click Save and Close to save the component.
