Configure a Stream

Quick Look

The following figure shows the Streams tab on the Warehouse Connector Services Config view.

The Streams tab allows you to perform the following:

Features	Description
	Add a stream.
	Delete a stream.
	Edit the stream.
	Start the stream.
	Stop the stream.
	Finalize the stream.
	Reload the stream. If you have added a new meta or if a new meta is added as part of content update to any of the sources, Log Decoder or Decoder, you need to reload the stream for the meta to be visible in the schema for the Reporting Engine. Reloading a stream does not have any impact on the data, but only the new meta list is fetched from the sources.

The following table describes the fields in the Streams tab:

Parameter	Description
Name	Name of the stream.
Sources	The sources associated with the stream.
Destination	The destinations associated with the stream.
Status	Status of the stream.

Stream Statistics

You can view the statistics of a configured stream. Click the icon next to the name of the stream.

The following parameters are displayed in the Stream Statistics:

Section	Parameter	Description
Stream
	Number of files in the permanent rejected folder	Determines the number of files in the permanent rejected folder (named, permfail) in the Warehouse Connector. The permanent rejected folder contains the files that Warehouse Connector failed to write to the destination.
	Rejected folder usage in percentage	Determines the disk usage of the rejected folder.
	Session Rate	Determines the rate at which the session is processed by the Warehouse Connector for the source.
Destination
	Status	Indicates the status of the destination.
Source
	Status	Indicate the status of the source.
	Sessions Behind	Determines that number of sessions that needs to be processed by the Warehouse Connector.
	Last Session read	Determines the last session id processed by the Warehouse Connector.

Change Stream Configuration

You can change configuration of a stream in runtime. In the Streams tab, click Change Configuration to change the configuration of the selected stream.

You can change the following parameters of the Stream Configuration:

Note: If you change the value of any parameter in stream configuration, make sure that you restart the stream.

After upgrading, if the values of Maximum Message Hold Count, Maximum Message Hold Interval and Maximum Message Hold Size are 3000000, 60 and 128 respectively, ensure that you assign the following values to the streams:

• Maximum Message Hold Count - 2400000
• Maximum Message Hold Interval - 600
• Maximum Message Hold Size - 512

You can assign these values by modifying the existing Stream configuration.

Parameter	Description
Aggregation Configuration
Aggregate max sessions	Determines the maximum number of sessions in a response for an aggregation request from the Warehouse Connector to the source .
Aggregation Interval	Determines the time between the responses from the source.
Loader Settings
Compress files on disk	Enable to compress files on disk. Supported values: Deflate - Provides smaller compressed files and good performance while generating reports. Off By default, the parameter is set to deflate.
Export Rollup Interval	Determines the roll-up interval for export files and also the directory structure the Warehouse Connector writes to the destination. For example: If the parameter is set to: Value Directory Structure hour /rsasoc/v1/[logs | sessions]/data/{year}/{month}/{day}/{hour} minute /rsasoc/v1/[logs | sessions]/data/{year}/{month}/{day}/{hour}/{minute} day /rsasoc/v1/[logs | sessions]/data/{year}/{month}/{day} If you change the value of the parameter, ensure that you restart the stream. Recommended value is hour.
Maximum Message Hold Count	Determines the maximum number of sessions to store in the memory before processing. Note: If you have deployed a Warehouse Connector Virtual Appliance, make sure that you change the default value of the parameter to 800000.
Maximum Message Hold Interval (Seconds)	Determines the maximum time (in seconds) to hold the sessions in memory before processing.
Maximum Message Hold Size	Determines the maximum size for the sessions to store in the memory before processing.
Remote Export Path	Determines the remote local mount point for HDFS (nfs://) and the location to export the data.
Page Size	Determines the maximum pages.
Stream Settings
Auto Startup	Enable to automatically start the stream whenever the Warehouse connector process is restarted. By default, the parameter is set to off.
