    9  * [https://www.orbit-lab.org/schedule/ Make a reservation] on the Schedular for a given tesbed
    10 
    11 Lets assume that you registered as user 'bob' and made a reservation for the 'grid' testbed. You then access the 'grid' console using the command:
    12 
    13  {{{
    14   ssh bob@console.grid.orbit-lab.org
    15  }}}

    18 == Getting Started ==
    19 
    20 Then, to query the status of some nodes on the 'grid' testbed, use the command:
    21 
    22  {{{
    23   omf stat all
    24   # will query the status of the entire set of 20x20 nodes on the 'grid'
    25  
    26   omf stat [[3,1],[5,6],[1,1..2]]
    27   # will query the status of nodes 3,1 and 5,6 and 1,1 and 1,2
    28 
    29   omf stat system:topo:circle
    30   # will query the status of the nodes in the topology file 'repository/system/topo/circle.rb'
    31 
    32   omf stat mytopo
    33   # will query the status of the nodes in the topology file './mytopo.rb'
    34 
    35   omf stat -c
    36   # will return a summary of the state of the nodes on the grid
    37  }}}

    41 
    42 The complete available options for this command is given by ''"omf help stat"'':
    43 
    44  {{{
    45   omf help stat
    46 
    47 Returns the status of the nodes in a testbed
    48 
    49 Usage:
    50       omf stat [-h]
    51       omf stat [-c] [DOMAIN]
    52       omf stat [TOPOLOGY] [DOMAIN]
    53  
    54       With:
    55       -h, --help    print this help message
    56       -c, --count   print a summary of the node status for the testbed DOMAIN
    57                     (default is the testbed where this command is executed)
    58       TOPOLOGY      a valid topology description or file without the trailing '.rb'
    59                     (default is the entire set of nodes on the default testbed)
    60  
    61       Some Examples:
    62                     omf stat all grid
    63                     omf stat 1,1..2
    64                     omf stat [[1,2],[1,1]] sb1
    65                     omf stat [[1,1],[2..6,1..2]]
    66                     omf stat system:topo:all
    67                     omf stat system:topo:circle
    68                     omf stat topo_grid_active
