Custom logging in Azure Data Factory - azure-data-factory

Question

I'm new to ADF and trying to build an Azure Data Flow Pipeline. I'm reading from a Snowflake data source and checking the data against several business rules. After each check, I'm writing the bad records to a csv file. Now, my requirement is that I need to create a log table which shows the business rule and the number of records that failed to pass that particular business rule. I've attached a screenshot of my ADF data flow as well as the structure of the table I'm trying to populate.
My idea was to create a stored proc that will be called at the end of each business rule, so that a record is created in the database. However, I'm unable to add an SP from the data flow. I found that I can get the rows written to a sink from the pipeline. However, I am not getting as to how I can tie the sink name and the rows written together and iterate the stored procedure for all the business rules?

Answer 1

I have considered sink1 and sink2 for storing the data that violates business-rule1 and rule2 respectively in my dataflow activity. I've created a stored procedure for recording the business rule and failed count in log-files. Then execute stored procedure activity in ADF is used and records are inserted in log files. Below are the steps.
Table for log-file.
CREATE TABLE [dbo].[log_file](
[BusinessRule] [varchar](50) NULL,--Business Rule
[count] [varchar](50) NULL--failed rows count
) ON [PRIMARY]
GO
Stored procedure for inserting records in log file through data factory.
Create proc [dbo].[usp_insert_log_file] (#BusinessRule varchar(100),#count varchar(10))
as
begin
insert into log_file values (#BusinessRule,#count)
end
-Dataflow activity has two sinks. It is chained with execute Stored procedure activity.
Stored Procedure has two parameters,
Enter the business rule in business_rule parameter and for count parameter,
In Stored procedure 1, Enter the corresponding business rule for sink1 in BusinessRule field, and for count field, pass the sink1's rowsWritten value from the output of data flow activity.
BusinessRule: 'Business_Rule_1'
Count:
#string(activity('Data flow1').output.runStatus.metrics.sink1.rowsWritten)`
Similarly in Stored Procedure2 activity, pass the sink2 count value and enter the corresponding business rule in parameters
BusinessRule: 'Business_Rule_2'
Count:
#string(activity('Data flow1').output.runStatus.metrics.sink2.rowsWritten)
In this way, We can insert data to logfile from dataflow activity using exec stored procedure activity.
