   Custom Metric Name: Enter a name for your Custom Metric. This Custom Metric name will be available in the Designer after saving. 
   SQL: Construct query strings to access data from your Database using Structured Query Language (SQL).

   Data Type: Selecting the appropriate Data Type ensures that your Custom Metrics will be synced correctly in Databox. 
  • Daily Values: This Data Type should be selected when your Metric reflects the most up-to-date Daily Value for the Metric. In Databox, the latest daily entry will be displayed for the Custom Metric.
  • Total Values: This Data Type should be selected when your Metric reflects the current total Value for the Metric.  In Databox, the latest entry will be displayed for the Custom Metric.

    For longer Date Ranges, data will be not aggregated and the most recent Value will be displayed for the selected Date Range. This is the main difference between "Total Values" and "Daily Values." 
  • Event Values: This Data Type should be selected when your Metric Value selection reflects individual Value(s) for the Metric at the specified Date/ Timestamp. This Data Type is the default selection because it is appropriate for the majority of use cases. 

    For longer Date Ranges, individual Metric Values will be aggregated for the entire Date Range and the aggregated Value will be displayed for the Custom Metric. 
   Data Preview: After clicking Run query, a Data Preview of the Custom Metric will be displayed. Daily Metric values are displayed in this section, along with the total Metric values for the Date Range in bold at the bottom. You can view the Data Preview for different Date Ranges by clicking on the tabs at the top of the Data Preview. 

How to create a Custom Snowflake Metric [Example]

The Query Builder for Snowflake is designed so you can directly enter SQL queries. For our example, we will use a Snowflake Data Source and create a Custom Metric that returns a list of Custom Names and their current Account Balance. 

 Navigate to   Metrics > Query Builder    
 Click the green  + New query button
 Select the appropriate Snowflake Data Source
 In order to accurately explain what this Custom Metric is reporting on, we'll name the Custom Metric "Customers by Balance" 
  In the SQL field, we will enter the query below. A semicolon at the end of the query is not necessary
SELECT start_date AS date, name, balance FROM sample_data
 We will select Total Values as the Data Type. This selection is based on the way data is stored and updated in our database
 Click Run query to generate a Data Preview of the Custom Metric

If you don’t see any data, double check your SQL query and try it directly in your Database. If no results are displayed there, an error exists in your query. You should also check to confirm that the Snowflake user has the necessary permissions to access the Database from Databox's public IP. 

 Once we confirm that these are the results we're looking for, we'll click Save to save the Custom Metric

Additional Information

  • Query results are limited to 1000 rows. If you expect your query to return over 1000 rows or if you're not sure how many rows will be returned, be sure to LIMIT the query
  • The query must contain a column named "Date." If you need to, use AS in your SELECT statement to satisfy this requirement
  • The Query won't recognize null values. In those cases please use a coalesce function
