NAME

perfSONAR_PS::Services::MP::Agent::ConstantValue - A perfsonar MP Agent class that returns a constant value.

DESCRIPTION

This module returns a constant value. It inherits from perfSONAR_PS::MP::Agent::Base to provide a consistent interface.

SYNOPSIS

  # create and setup a new Agent  
  my $agent = perfSONAR_PS::Services::MP::Agent::ConstantValue( 5 );
  
  # collect the results (i.e. run the command)
  if( $mp->collectMeasurements() == 0 )
  {
        
        # get the raw datastructure for the measurement
        print "Results:\n" . $self->results() . "\n";

  }
  # opps! something went wrong! :(
  else {
    
    print STDERR "Command: '" . $self->commandString() . "' failed with result '" . $self->results() . "': " . $agent->error() . "\n"; 
    
  }

new( $value )

Creates a new agent class

  $value = constant value to set

init()

No initiation needed, do nothing

collectMeasurements( )

Always okay as long as the constant value is set.

 -1 = something failed
  0 = command ran okay

results( )

Returns the results (ie the constant value assigned in the constructor). No need to redefine here as it's inherited.
