qstat - show status of pbs batch jobs
qstat [-f][-W site_specific] [job_identifier... | destination...]
qstat [-a|-i|-r] [-n] [-s] [-G|-M] [-u user_list] [job_identifier... | destination...]
qstat -Q [-f][-W site_specific] [destination...]
qstat -q [-G|-M] [destination...]
qstat -B [-f][-W site_specific] [server_name...]
The qstat command is used to request the status of jobs, queues, or a batch server. The requested status is written to standard out.
When requesting job status, synopsis format 1 or 2, qstat will output information about each job_identifier or all jobs at each destination . Jobs for which the user does not have status privilege are not displayed.
When requesting queue or server status, synopsis format 3 through 5, qstat will output information about each desti_nation .
If neither the -Q nor the -B option is given, the operands on the qstat command must be either job identifiers or destinations identifiers.
If the operand is a job identifier, it must be in the following
form:
sequence_number[.server_name][@server]
where sequence_number.server_name is the job identifier
assigned at submittal time, see qsub. If the .server_name
is omitted, the name of the default server will be used.
If @server is supplied, the request will be for the job
identifier currently at that Server.
If the operand is a destination identifier, it is one of
the following three forms:
queue
@server
queue@server
If queue is specified, the request is for status of all
jobs in that queue at the default server. If the @server
form is given, the request is for status of all jobs at
that server. If a full destination identifier,
queue@server , is given, the request is for status of all
jobs in the named queue at the named server.
If the -Q option is given, the operands are destination identifiers as specified above. If queue is specified, the status of that queue at the default server will be given. If queue@server is specified, the status of the named queue at the named server will be given. If @server is specified, the status of all queues at the named server will be given. If no destination is specified, the status of all queues at the default server will be given.
If the -B option is given, the operand is the name of a server.
Displaying Job Status
If job status is being displayed in the default format and the -f option is not specified, the following items are displayed on a single line, in the specified order, separated by white space:
If job status is being displayed and the -f option is
specified, the output will depend on whether qstat was
compiled to use a Tcl interpreter. See the configuration
section for details. If Tcl is not being used, full display
for each job consists of the header line:
Job Id: job identifier
Followed by one line per job attribute of the form:
attribute_name = value
If any of the options -a, -i, -r, -u, -n, -s, -G or -M are provided, the alternative display format for jobs is used. The following items are displayed on a single line, in the specified order, separated by white space:
Displaying Queue Status
If queue status is being displayed and the -f option was not specified, the following items are displayed on a single line, in the specified order, separated by white space:
If queue status is being displayed and the -f option is
specified, the output will depend on whether qstat was
compiled to use a Tcl interpreter. See the configuration
section for details. If Tcl is not being used, the full
display for each queue consists of the header line:
Queue: queue_name
Followed by one line per queue attribute of the form:
attribute_name = value
If the -q option is specified, queue information is displayed in the alternative format: The following information is displayed on a single line:
Displaying Server Status
If batch server status is being displayed and the -f option is not specified, the following items are displayed on a single line, in the specified order, separated by white space:
If server status is being displayed and the -f option is
specified, the output will depend on whether qstat was
compiled to use a Tcl interpreter. See the configuration
section for details. If Tcl is not being used, the full
display for the server consist of the header line:
Server: server name
Followed by one line per server attribute of the form:
attribute_name = value
The qstat command will write a diagnostic message to standard error for each error occurrence.
If qstat is compiled with an option to include a Tcl interpreter, using the -f flag to get a full display causes a check to be made for a script file to use to output the requested information. The first location checked is $HOME/.qstatrc. If this does not exist, the next location checked is administrator configured. If one of these is found, a Tcl interpreter is started and the script file is passed to it along with three global variables. The command line arguments are split into two variable named flags and operands . The status information is passed in a variable named objects . All of these variables are Tcl lists. The flags list contains the name of the command (usually qstat") as its first element. Any other elements are command line option flags with any options they use, presented in the order given on the command line. They are broken up individually so that if two flags are given together on the command line, they are separated in the list. For example, if the user typed
qstat -QfWbigdisplay
the flags list would contain
qstat -Q -f -W bigdisplay
The operands list contains all other command line arguments following the flags. There will always be at least one element in operands because if no operands are typed by the user, the default destination or server name is used. The objects list contains all the information retrieved from the server(s) so the Tcl interpreter can run once to format the entire output. This list has the same number of elements as the operands list. Each element is another list with two elements. The first element is a string giving the type of objects to be found in the second. The string can take the values server", queue", job or error". The second element will be a list in which each element is a single batch status object of the type given by the string discussed above. In the case of error", the list will be empty. Each object is again a list. The first element is the name of the object. The second is a list of attributes. The third element will be the object text. All three of these object elements corespond with fields in the structure batch_status which is described in detail for each type of object by the man pages for pbs_statjob(3) , pbs_statque(3) , and pbs_statserver(3) . Each attribute in the second element list whose elements correspond with the attrl structure. Each will be a list with two elements. The first will be the attribute name and the second will be the attribute value.
Upon successful processing of all the operands presented to the qstat command, the exit status will be a value of zero.
If the qstat command fails to process any operand, the command exits with a value greater than zero.
