====== CSV Data Stream ======

Use the CSV Data Stream to configure tag-to-tag mapping via a CSV file.

===== Data File Format =====

The example CSV file below contains mappings to stream a few tags from the Telemetry data source to the RabbitMQ Provider.

<code>
SOURCE_DSN,SOURCE_TAG,DESTINATION_DSN,DESTINATION_TAG
Telemetry,performance_counters.memory.available_mbytes#value,RabbitMQ Producer,performance_counters.memory.available_mbytess#value
Telemetry,performance_counters.processor.pct_processor_time#value,RabbitMQ Producer,performance_counters.processor.pct_processor_time#value
Telemetry,performance_counters.processor.pct_processor_time#value,RabbitMQ Producer,performance_counters.processor.pct_processor_time#value
Telemetry,performance_counters.logicaldisk.c.pct_free_space#value,RabbitMQ Producer,performance_counters.logicaldisk.c.pct_free_space#value
</code>

//This type of configuration could be employed to push telemetery from a data core node to an App Store Connect instance where the tags are monitored.
//  

===== Data File Location =====

The default location for CSV data stream mappings files is:

  %ProgramData%\Intelligent Plant\Data Core Application Host\Service\Applications\App Store Connect\Data\CsvDataStreamMappings
  
To use an alternative location, create an [[data_core:update_safe_configuration|Update-safe Configuration]] file and configure the following setting:

   <add key="dataCore:dataStream:csv:baseDirectory" value="Data/CsvDataStreamMappings" />
   
Enter the path in the value property (NB. the path must be relative to the Data Core root folder).

===== Licence Requirements =====

None.
