Tuning Parser Storm Parmeters

You can tune some of your parser Storm parameters using the Management module. If you need to tune Storm parameters that are not included in the Management moduel, see the section called “Create a Parser for Your New Data Source by Using the CLI”.

From the list of sensors in the main window, select your new sensor.
Click (edit) in the toolbar.
The Management module displays the sensor panel for the new sensor.
Note
Your sensor must be running and producing data before you can add tuning information.
In the STORM SETTINGS field, click (expand window).
The Management module displays the Configure Storm Settings panel.
You can tune the following Storm parameters:
Spout Parallelism
The Kafka spout parallelism (default to 1). You can override the default on the command line.
Spout Num Tasks
The number of tasks for the spout (default to 1). You can override the default on the command line.
Parser Parallelism
The parser bolt parallelism (default to 1). You can override the default on the command line.
Parser Num Tasks
The number of tasks for the parser bolt (default to 1). You can override the default on the command line.
Error Writer Parallelism
The error writer bolt parallelism (default to 1). You can override the default on the command line.
Error Writer Num Tasks
The number of tasks for the error writer bolt (default to 1). You can override the default on the command line.
Spout Config
A map representing a custom spout configuration (this is a map). You can override the default on the command line.
Storm Config
The storm configuration to use (this is a map). You can override this on the command line. If both are specified, they are merged with CLI properties taking precedence.
