Returns: (return code, message) if the callback is set, use callback to display the status and error. =cut #-------------------------------------------------------------------------------- sub stop { # starting sub routine print "gangliamon::stop called\n"; my $noderef=shift; if ($noderef =~ /xCAT_monitoring::gangliamon/) { $noderef=shift; } my $scope=shift; my $callback=shift; my $localhost=hostname(); my $OS=`uname`; my $res_gmond; if ( $OS =~ /AIX/ ) { $res_gmond = `/etc/rc.d/init.d/gmond stop 2>&1`; } else { $res_gmond = `/etc/init.d/gmond stop 2>&1`; } if ($?) { if ($callback) { my $resp={}; $resp->{data}->[0]="$localhost: Ganglia Gmond not stopped successfully: $res_gmond \n"; $callback->($resp); } else { xCAT::MsgUtils->message('S', "[mon]: $res_gmond \n"); } return(1,"Ganglia Gmond not stopped successfully. \n"); } my $res_gmetad; if ( $OS =~ /AIX/ ) { $res_gmetad = `/etc/rc.d/init.d/gmetad stop 2>&1`; } else { $res_gmetad = `/etc/init.d/gmetad stop 2>&1`; } if ($?) { if ($callback) { my $resp={}; $resp->{data}->[0]="$localhost: Ganglia Gmetad not stopped successfully:$res_gmetad \n"; $callback->($resp); } else { xCAT::MsgUtils->message('S', "[mon]: $res_gmetad \n"); } return(1,"Ganglia Gmetad not stopped successfully. \n"); } if ($scope) { #opening if scope my $OS=`uname`; my $pPairHash=xCAT_monitoring::monitorctrl->getMonServer($noderef); if (ref($pPairHash) eq 'ARRAY') { if ($callback) { my $resp={}; $resp->{data}->[0]=$pPairHash->[1]; $callback->($resp); } else { xCAT::MsgUtils->message('S', "[mon]: " . $pPairHash->[1]); } return (1, ""); } #identification of this node my @hostinfo=xCAT::Utils->determinehostname(); my $isSV=xCAT::Utils->isServiceNode(); my %iphash=(); foreach(@hostinfo) {$iphash{$_}=1;} if (!$isSV) { $iphash{'noservicenode'}=1;} my @children; foreach my $key (keys (%$pPairHash)) { #opening foreach1 my @key_a=split(':', $key); if (! $iphash{$key_a[0]}) { next; } my $mon_nodes=$pPairHash->{$key}; foreach(@$mon_nodes) { #opening foreach2 my $node=$_->[0]; my $nodetype=$_->[1]; if (($nodetype) && ($nodetype =~ /$::NODETYPE_OSI/)) { push(@children,$node); } } #closing foreach2 } #closing foreach1 my $result = undef; my $rec = undef; if( exists($children[0]) ){ $rec = join(',',@children); } if($rec){ if ( $OS =~ /AIX/ ) { $result = `XCATBYPASS=Y $::XCATROOT/bin/xdsh $rec /etc/rc.d/init.d/gmond stop 2>&1`; } else { $result = `XCATBYPASS=Y $::XCATROOT/bin/xdsh $rec /etc/init.d/gmond stop 2>&1`; } } if ($result) { if ($callback) { my $resp={}; $resp->{data}->[0]="$localhost: $result\n"; $callback->($resp); } else { xCAT::MsgUtils->message('S', "[mon]: $result\n"); } } } #closing if scope if ($callback) { my $resp={}; $resp->{data}->[0]="$localhost: stopped. \n"; $callback->($resp); } return (0, "stopped"); } #-------------------------------------------------------------------------------- =head3 supportNodeStatusMon This function is called by the monitorctrl module to check if Ganglia can help monitoring and returning the node status.
