Name
       condor_checkpoint send - a checkpoint command to jobs running on specified hosts

Synopsis
       condor_checkpoint [-help -version]

       condor_checkpoint[-debug]  [-pool  centralmanagerhostname[:portnumber]]	[-name hostnamehostname-addr "<a.b.c.d:port>""<a.b.c.d:port>"-con-
       straint expression-all]

Description
       condor_checkpoint sends a checkpoint command to a set of machines within a single pool. This causes the startd daemon on each of the speci-
       fied  machines  to  take  a  checkpoint of any running job that is executing under the standard universe. The job is temporarily stopped, a
       checkpoint is taken, and then the job continues. If no machine is specified, then the command is sent to the machine that issued  the  con-
       dor_checkpoint command.

       The  command  sent  is  a periodic checkpoint. The job will take a checkpoint, but then the job will immediately continue running after the
       checkpoint is completed. condor_vacate, on the other hand, will result in the job exiting (vacating) after it produces a checkpoint.

       If the job being checkpointed is running under the standard universe, the job produces a checkpoint and then continues running on the  same
       machine.  If  the  job  is  running under another universe, or if there is currently no Condor job running on that host, then condor_check-
       pointhas no effect.

       There is generally no need for the user or administrator to explicitly run condor_checkpoint. Taking checkpoints of running Condor jobs	is
       handled automatically following the policies stated in the configuration files.

Options
       -help

	  Display usage information

       -version

	  Display version information

       -debug

	  Causes debugging information to be sent to  stderr , based on the value of the configuration variable  TOOL_DEBUG

       -pool centralmanagerhostname[:portnumber]

	  Specify a pool by giving the central manager's host name and an optional port number

       -name hostname

	  Send the command to a machine identified by hostname

       hostname

	  Send the command to a machine identified by hostname

       -addr <a.b.c.d:port>

	  Send the command to a machine's master located at "<a.b.c.d:port>"

       <a.b.c.d:port>

	  Send the command to a machine located at "<a.b.c.d:port>"

       -constraint expression

	  Apply this command only to machines matching the given ClassAd expression

       -all

	  Send the command to all machines in the pool

Exit Status
       condor_checkpointwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.

Examples
       To send a condor_checkpoint command to two named machines:

       % condor_checkpoint   robin cardinal

       To send the condor_checkpointcommand to a machine within a pool of machines other than the local pool, use the -pooloption. The argument is
       the name of the central manager for the pool. Note that one or more machines within the pool must be specified as the targets for the  com-
       mand. This command sends the command to a the single machine named cae17within the pool of machines that has condor.cae.wisc.eduas its cen-
       tral manager:

       % condor_checkpoint  -pool condor.cae.wisc.edu -name cae17
