Null percent metrics

Step 2 (Configure Metric)

After you finish Step 1 (Metric Info), Step 2 (Configure Metric) appears in the main form:

11251125
  1. Under Custom Metric Info, choose a datasource, schema, table, and a column that you'll check for nulls. Optionally, to see a data sample from the table, select View Sample Data.
  2. Under Configure metric, some fields may be inheriting values from the table. You'll need to enter values for any that are empty. To use your own values for these fields, select Override Settings to unlock the fields for editing. Note that if the table you chose has partitions, Lightup detects them and displays relevant settings for them just below the heritable settings. If you decide instead that the metric should use the table's settings, select Inherit Settings to use the current table settings.
  3. Optionally, select a Seasonality to indicate how to determine valid periods for running the metric's query. If you choose Auto seasonality, Lightup calculates the seasonality for you. Select the gear icon to add custom override periods.
  4. Optionally, to create a WHERE clause select Add +. New fields appear under Where clause that you can use to specify the necessary condition. To delete a WHERE clause, use the waste bin icon beside it to the right.

Editing a metric

When you edit an existing metric:

  • You'll see an option to view the metric's recent query history as well as a preview.
  • The Create command changes to Save when you edit an existing metric
  1. Select View sample data to see a sample set of rows from the data asset. Lightup returns 100 rows of data from the source table, including metadata. Select Stop Viewing when you're done.
  2. Optionally, adjust the date range for the preview. If you adjust the range, you must pick a start date and an end date.
  3. Select Preview to see a chart of the metric for the date range from the preceding step.

Cancel a preview

Some datasources let you cancel a preview, for example because you noticed that date range was wrong. If cancelling is supported, you'll see a Cancel button.

  1. After you're satisfied with the preview, select Create at the top right corner. The Explorer tab opens and displays your new metric in the Explorer tree.
