Puppet ganglia Module

Description

This puppet module will install and configure the ganglia gmond & gmetad daemons + web front end.

It has been tested on:

el5.x with custom rpm installation of ganglia-gmond not provided by EPEL an which is custom built.

Examples

ganglia::gmond

# unicast
$udp_recv_channel = [
  { port => 8649, bind => 'localhost' },
  { port => 8649, bind => '0.0.0.0' },
]
$udp_send_channel = [
  { port => 8649, host => 'test1.example.org', ttl => 2 },
  { port => 8649, host => 'test2.example.org', ttl => 2 },
]
$tcp_accept_channel = [
  { port => 8649 },
]

# multicast
$udp_recv_channel = [
  { mcast_join => '239.2.11.71', port => 8649, ttl => 1 } 
]
$udp_send_channel = [
  { mcast_join => '239.2.11.71', port => 8649, bind => '239.2.11.71' } 
]
$tcp_accept_channel = [
  { port => 8649 },
]

class{ 'ganglia::gmond':
  cluster_name       => 'example grid',
  cluster_owner      => 'ACME, Inc.',
  cluster_latlong    => 'N32.2332147 W110.9481163',
  cluster_url        => 'www.example.org',

  udp_recv_channel   => $udp_recv_channel,
  udp_send_channel   => $udp_send_channel,
  tcp_accept_channel => $tcp_accept_channel,
}

ganglia::gmetad

$clusters = [
  { 
    name     => 'test', 
    address  => ['test1.example.org', 'test2.example.org'],
  },
]

class{ 'ganglia::gmetad':
  clusters => $clusters,   
  gridname => 'my grid',   
}

ganglia::web

class{ 'ganglia::web': }

class{ 'ganglia::web':
  $ganglia_ip = '192.168.0.1',
  $ganglia_port = 8652,
}

$::osfamily = RedHat and EPEL packages

As of 2012-11-16, the stable EPEL repos for el5 and el6 contain, respectively, packages for ganglia 3.0.7 and 3.1.7. The ganglia UDP protocol for communication between gmond daemons changed incompatibly between 3.0.x and 3.1.x. However, the TCP based protocol gmetad uses to poll gmond agents has remained compatible.

If it's desirable to stick with the EPEL packages, a possible way of dealing with this is divide a group of hosts into two clusters based on $::lsbmajdistrelease (which should imply gmond version without having to install a custom fact). The example below divides the previous "mycluster" into "mycluster_el5" and "mycluster_el6". Note that you will also have to configure gmetad to pull a gmond agent from each of these new clusters.

$udp_recv_channel = [
  { port => 8649, bind => 'localhost' },
  { port => 8649, bind => '0.0.0.0' },
]
case $::lsbmajdistrelease {
  5: {
    # epel for el5.x has 3.0.x, which will not work with gmond in 3.1.x
    $udp_send_channel = [
      { port => 8649, host => 'gmond-3-0_host1.example.org', ttl => 2 },
      { port => 8649, host => 'gmond-3-0_host2.example.org', ttl => 2 },
    ]
    $cluster_name = 'mycluster_el5'
  }
  6, default: {
    # epel for el6.x has 3.1.x
    $udp_send_channel = [
      { port => 8649, host => 'gmond-3-1_host1.example.org', ttl => 2 },
      { port => 8649, host => 'gmond-3-1_host2.example.org', ttl => 2 },
    ]
    $cluster_name = 'mycluster_el6'
  }
}
$tcp_accept_channel = [
  {port => 8649},
]

class{ 'ganglia::gmond':
  cluster_name       => 'example grid',
  cluster_owner      => 'ACME, Inc.',
  cluster_latlong    => 'N32.2332147 W110.9481163',
  cluster_url        => 'www.example.org',
  host_location      => 'example computer room',
  udp_recv_channel   => $udp_recv_channel,
  udp_send_channel   => $udp_send_channel,
