Random Collector Plugin

Introduction

This plugin adds the new collector type. It actually doesn't collect anything, but generates randomly generated values. The main purpose of this plugin is testing various aspects of RRFW, and particularly its modular Collector design.

Installation

Unpack RRFW main distribution and the plugin in some directories. From RRFW distribution directory, run

  ./configure --with-plugins=../rrfw-plugin-randomcollector-0.0.1
  make install

After RRFW installation has finished, add the following lines to your rrfw-siteconfig.pl file:

  push( @RRFW::Collector::loadModules, 'RRFW::Collector::Random' );
  push( @RRFW::Validator::loadLeafValidators, 'RRFW::Collector::Random' );

That is all, now you can use the parameters described below in your XML configuration.

genrandomcfg utility may be used to create a typical configuration for the random collector.

XML configuration parameters

• collector-type
  
New value random is supported by this plugin.
• rnd-baseline-type
  
Mandatory when collector-type=random. Values supported: sin (Sine baseline curve), flat (horizontal baseline).
• rnd-baseline-height
  
Mandatory when collector-type=random. Specifies the constant baseline height above the X axis.
• rnd-amplitude
  
Mandatory when collector-type=random. Specifies the amplitude of the random value.
• rnd-baseline-period, rnd-baseline-offset, rnd-baseline-amplitude
  
Mandatory when collector-type=random and rnd-baseline-type=sin. These options determine the parameters of the sine curve: Y = height + amplitude * sin( 2*pi*(TIME+offset)/period )
