=head1 NAME
B<startmon> - Starts a plug-in module to monitor the xCAT cluster.
=head1 SYNOPSIS
I<startmon [-h| --help]>
I<startmon [-v| --version]>
I<startmon I<name> [-n|--nodestatmon] [-s|--settings settings]>
=head1 DESCRIPTION
This command is used to register a monitoring plug-in module and invoke it to monitor the xCAT cluster. A monitoring plug-in module acts as a bridge that connects a 3rd party monitoring software and the xCAT cluster. The plug-in module will be registered in the xCAT I<monitoring> database table. A registered plug-in module is automatically started by the I<xcatd>.
=head1 Parameters
I<name> is the name of the monitoring plug-in module. For example, if the the I<name> is called I<xxx>, then the actual file name that the xcatd looks for is I</opt/xcat/lib/perl/xCAT_monitoring/xxx.pm>. Use I<lsmon -a> command to list all the monitoring plug-in modules that can be used.
I<settings> is the monitoring plug-in specific settings. It is used to customize the behavior of the plug-in or configure the 3rd party software. Format: I<[key-value],[key=value]...> Please note that the square brackets are needed here. Use I<lsmon name -d> command to look for the possbile setting keys for a plug-in module.
=head1 OPTIONS
B<-h | -help> Display usage message.
B<-n | -nodestatmon> Indicate that this monitoring plug-in will be used for feeding the node liveness status to the xCAT I<nodelist> table.
B<-s | -settings> Specifies the plug-in specific settings. These settings will be used by the plug-in to customize certain entities for the plug-in or the third party monitoring software. e.g. [mon_interval=10],[toggle=1].
B<-v | -version > Command Version.
B<-V | -verbose> Verbose output.
=head1 RETURN VALUE
0 The command completed successfully.
1 An error has occurred.
=head1 EXAMPLES
1. To start gangliamon plug-in module (which interacts with Ganglia monitoring software) to monitor the xCAT cluster, enter:
startmon gangliamon
2. To start rmcmon plug-in module (which interacts with IBM's RSCT monitoring software) to monitor the xCAT cluster and have it feed the node liveness status to xCAT's I<nodelist> table, enter:
startmon rmcmon -n
3. To start xcatmon plug-in module to feed the node liveness status to xCAT's I<nodelist> table, enter:
startmon rmcmon -n -s [ping-interval=2]
where 2 is the number of minutes between the pings.
