= Cluster Monitoring =
The cluster resources and performance needs to be constantly monitored, and the users need to be tracked.

We assume the following configuration: ||Ganglia || 3.0.4 ||!JobMonarch || 0.2

Ganglia
''Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids.'' * Download the latest release of the ''Ganglia Monitoring Core'' from [http://ganglia.sourceforge.net/ http://ganglia.sourceforge.net]. * Install Ganglia into ''/usr/local/ganglia'', its web frontend into ''/usr/local/ganglia/html/', and its databases into ''/usr/local/ganglia/rrds/'. * Install the ''Ganglia Monitoring Daemon'' (gmond) on each node, and the ''Ganglia Meta Daemon'' (gmetad) on the the head node.

=== Ganglia Monitoring Daemon === * Configure, build and install Ganglia on each slave node (only with ''gmond''): {{{
./configure --prefix=/usr/local
}}}
and on the master node (with ''gmond'' and ''gmetad''): {{{
./configure --prefix=/usr/local --with-gmeta
}}}

• Initialise the configuration file for ''gmond'': {{{
  gmond --default >> /etc/gmond.conf
  }}}

• Configure the ''Ganglia Monitoring Daemon'' in ''/etc/gmond.conf'': * Set the name of the cluster: {{{
  cluster {
  name = "ProCKSI"
  }
  }}} * Set the IP address and port for multicast data exchange: {{{
  udp_send_channel {
  mcast_join = 239.2.11.71
  port = 8649
  }
  udp_recv_channel {
  mcast_join = 239.2.11.71
  port = 8649
  bind = 239.2.11.71
  }
  }}}

• Copy start-up script for ''gmond'': {{{
  cp ./gmond/gmond.init /etc/init.d/gmond
  }}}

• Add additional route for correct data exchange via multicast using the ''internal'' interface (''eth0''). Modify ''/etc/inid.d/gmond'': {{{
  #Add multicast route to internal interface
  /sbin/route add -host 239.2.11.71 dev eth0
  daemon $GMOND
  }}} {{{
  #Remove multicast route to internal interface
  /sbin/route delete -host 239.2.11.71 dev eth0
  killproc gmond
  }}}
• Make the Ganglia Monitoring Daemon start at bootup. {{{
  /sbin/chkconfig gmond on
  }}}
• Start the Ganglia Monitoring Daemon: {{{
  /sbin/service gmond start
  }}}

=== Ganglia Meta Daemon === * Install and configure the ''Ganglia Meta Daeomn'' (gmetad) on the master node.

• Make the Ganglia Meta Daemon start at bootup. {{{
  /sbin/chkconfig --add gmetad
  /sbin/chkconfig gmetad on
  }}}
• Start the Ganglia Meta Daemon: {{{
  /sbin/service gmetad start
  }}}

• If the pie chart diagrams do not show up, you have to install the ''php-gd'' packages.

=== Further Customisation ===
In order to display more fine-grained time intervals, edit the following files in ''/usr/local/ganglia/html/'': * '''header.php''' {{{
if (!$physical) {
$context_ranges[]="10 minutes";
$context_ranges[]="20 minutes";
$context_ranges[]="30 minutes";
$context_ranges[]="1 hour";
$context_ranges[]="2 hours";
$context_ranges[]="4 hours";
$context_ranges[]="8 hours";
$context_ranges[]="12 hours";
$context_ranges[]="1 day";
$context_ranges[]="2 days";
$context_ranges[]="week";
$context_ranges[]="month";
$context_ranges[]="year";
}}}

• '''get_context.php''' {{{
  switch ($range) {
  case "10 minutes": $start = -600; break;
  case "20 minutes": $start = -1200; break;
  case "30 minutes": $start = -1800; break;
  case "1 hour": $start = -3600; break;
  case "2 hours": $start = -7200; break;
  case "4 hours": $start = -14400; break;
  case "8 hours": $start = -28800; break;
  case "12 hours": $start = -43200; break;
  case "1 day": $start = -86400; break;
  case "2 days": $start = -172800; break;
  case "week": $start = -604800; break;
  case "month": $start = -2419200; break;
  case "year": $start = -31449600; break;
  }}}

!JobMonarch
!JobMonarch is an add-on to Ganglia which provides PBS job monitoring through the web browser.

See [http://subtrac.rc.sara.nl/oss/jobmonarch/wiki/Documentation http://subtrac.rc.sara.nl/oss/jobmonarch/wiki/Documentation] for information on requirements, configuration and installation.
