perfSONAR_PS::Services::MA::PingER - A module that implements MA service.

This module aims to offer simple methods for dealing with requests for information, and the related tasks of intializing the backend storage.

    use perfSONAR_PS::Services::MA::PingER;

    


    my %conf = ();
    $conf{"METADATA_DB_TYPE"} = "xmldb";
    $conf{"METADATA_DB_NAME"} = "/home/netadmin/LHCOPN/perfSONAR-PS/MP/Ping/xmldb";
    $conf{"METADATA_DB_FILE"} = "pingerstore.dbxml";
    $conf{"SQL_DB_USER"} = "pinger";
    $conf{"SQL_DB_PASS"} = "pinger";
    $conf{"SQL_DB_DB"} = "pinger_pairs";

    my $pingerMA_conf = perfSONAR_PS::SimpleConfig->new( -FILE => 'pingerMA.conf', -PROMPTS => \%CONF_PROMPTS, -DIALOG => '1');
    my $config_data = $pingerMA_conf->parse(); 
    $pingerMA_conf->store;
    %conf = %{$pingerMA_conf->getNormalizedData()}; 
    my $ma = perfSONAR_PS::MA::PingER->new( \%con );

    # or
    # $self = perfSONAR_PS::MA::PingER->new;
    # $self->setConf(\%conf);

        


    $self->init;  
    while(1) {
      $self->receive;
      $self->respond;
    }  

This API is a work in progress, and still does not reflect the general access needed in an MA. Additional logic is needed to address issues such as different backend storage facilities.

The offered API is simple, but offers the key functions we need in a measurement archive.

create a new instance of the PingER MA

Initiate the MA; configure the configuration defaults, and message handlers.

accessor/mutator for database instance

accessor/mutator for the lookup service

Should the instance of the PingER register with a LS?

register all the metadata that our ma contains to the LS

main access into MA from Daemon Architecture

actually do something the incoming $request message.

     messageType: The type of the message where the merging is occurring
     eventType: The event type in at least one of the md that caused this handler to be chosen
     parentMd: The metadata that was metadataIdRef'd by the childMd
     childMd: The metadata that needs to be merged with its parent
