=head1 NAME

Xymon::Monitor::Informix - Hobbit / Xymon Informix Database Monitor

=head1 SYNOPSIS

  use Xymon::Monitor::Informix;
  
  #
  # All parameters ar optional and defaults are shown
  #
  
  my $informix = Xymon::Monitor::Informix->new({
		CONTIME			=>	5,
		CONTRY			=>	1,
		INFORMIXDIR		=>	"/informix/",
		LD_LIBRARY_PATH	=>	"/informix/lib:/informix/lib/esql/",
		HOBBITHOME		=>	"/home/hobbit/client/"			
  });
  
  #
  # 
  $informix->check();


=head1 DESCRIPTION

Tries to connect to all instances specified your sqlhosts file and
sends the status to your Xymon/Hobbit Server. Each server will be sent a single
test called database which is red if any single database is down. Status page
shows status of all db instances on that host.

You must install DBI and DBD::Informix for this module to work.

=head1 CONSTRUCTOR

	my $informix = Xymon::Monitor::Informix->new({.....});
	
All parameters are optional and are listed below:

	CONTIME - connection timeout (default 5)
	CONTRY - connection tries (default 1)
	INFORMIXDIR - informix directory ($INFORMIXDIR) (default /informix)
	LD_LIBRARY_PATH	- default (/informix/lib:/informix/lib/esql/)
	HOBBITHOME - hobbit/xymon dir (default home/hobbit/client/)	

The script listed in the synopsis is all you need to send updates to Xymon/Hobbit,
however you will also need to add the script to your hobbitlaunch.cfg file.

A group of lines like the following should work. 

	[informix]
        ENVFILE /home/hobbit/server/etc/hobbitserver.cfg
        NEEDS hobbitd
        CMD /home/hobbit/server/ext/ifxcheck.pl
        LOGFILE $BBSERVERLOGS/informix.log
        INTERVAL 30


The installation script asks you where you want to install the included test script. 
It should go in your hobbit ext directory.

=head1 METHODS

	check() - checks all found instances from sqlhosts and sends status
	to master hobbit server.
