KPI Back Population
If you create a new KPI or modify an existing one, Optimize invokes a back-population feature that automatically generates the appropriate KPI instances and back-populates baseline statistics from any existing data. In this case, back-populating means that the relevant data displays are re-calculated in light of the new KPI(s). During back population, data is re-parsed according to the new KPI specifications, but the fundamental contents of the underlying data set are not altered by this feature.
Note that back-population occurs only if there is data relevant to the KPI; if there is no relevant data, back-population does not occur. KPI back population is managed by the Optimize Job Manager and can be monitored through the Job Manager interface.
Customers can use the KPI back-population feature to update their data displays in a couple of scenarios as described below.
If you want to recast your existing data in light of new or altered KPIs, you can make the desired KPI changes and
Optimize will automatically invoke the back-population feature to recast your statistics. This means that both historical and current data is re-evaluated in light of the new or updated KPIs.
If you have added back-dated events to your
Optimize data set, or if you have injected legacy data from another data set into your
Optimize data set, you can delete and recreate your existing KPIs to view graphs and statistics in light of the newly added data. Deleting and recreating existing KPIs is the same as creating new KPIs from an
Optimize perspective.
When you create a new KPI or update an existing KPI, Optimize does the following:
Displays all KPI Instances for that KPI on the Overview and Summary pages.
Displays all KPI Instance detail graphs for all KPI instances.
Displays baseline statistics (historical data) on KPI Instance Detail graphs for each KPI instance.
Displays all diagnosis (trending up/down, sloping up/down, above/below mean, etc.) icons for the KPI.
Note:
If you have a large data set, KPI back-population can take some time to complete. Be aware of this whenever you make a change that initiates back population.
When you create a new KPI, Optimize displays a message indicating that back-population is being initiated, if applicable. You can check the Job Manager Audit page to confirm that back-population has been completed. To view the Job Manager Audit page, click Analytics > Job Management > Job Audit in My webMethods.
