condor_ q

Display information about jobs in queue

Synopsis

condor_ q [-help] [-global] [-submitter submitter] [-name name] [-pool centralmanagerhostname[:portnumber]] [-analyze] [-run] [-hold] [-goodput] [-io] [-dag] [-long] [-format formatter attribute] [-cputime] [-currentrun] [{cluster | cluster.process | owner | -constraint expression ... } ]

Description

condor_ q displays information about jobs in the Condor job queue. By default, condor_ q queries the local job queue but this behavior may be modified by specifying:

To restrict the display to jobs of interest, a list of zero or more restrictions may be supplied. Each restriction may be one of:

If no owner restrictions are present in the list, the job matches the restriction list if it matches at least one restriction in the list. If owner restrictions are present, the job matches the list if it matches one of the owner restrictions and at least one non-owner restriction.

If the -long option is specified, condor_ q displays a long description of the queried jobs by printing the entire job classad. The attributes of the job classad may be displayed by means of the -format option, which displays attributes with a printf(3) format. (Multiple -format options may be specified in the option list to display several attributes of the job.) If neither -long or -format are specified, condor_ q displays a a one line summary of information as follows:

ID
The cluster/process id of the condor job.
OWNER
The owner of the job.
SUBMITTED
The month, day, hour, and minute the job was submitted to the queue.
RUN_TIME
Wall-clock time accumulated by the job to date in days, hours, minutes, and seconds.
ST
Current status of the job. U = unexpanded (never been run), H = on hold, R = running, I = idle (waiting for a machine to execute on), C = completed, and X = removed.
PRI
User specified priority of the job, ranges from -20 to +20, with higher numbers corresponding to greater priority.
SIZE
The virtual image size of the executable in megabytes.
CMD
The name of the executable.

If the -dag option is specified, the OWNER column is replaced with NODENAME for jobs started by Condor DAGMan.

NOTE: The -dag option has no effect on a pre-v6.3.0 Condor queue, because older condor_ schedd daemons don't pass the necessary DAG information to their jobs.

If the -run option is specified, the ST, PRI, SIZE, and CMD columns are replaced with:

HOST(S)
The host where the job is running. For PVM jobs, a host count is displayed instead.

If the -goodput option is specified, the ST, PRI, SIZE, and CMD columns are replaced with:

GOODPUT
The percentage of RUN_TIME for this job which has been saved in a checkpoint. A low GOODPUT value indicates that the job is failing to checkpoint. If a job has not yet attempted a checkpoint, this column contains [?????].
CPU_UTIL
The ratio of CPU_TIME to RUN_TIME for checkpointed work. A low CPU_UTIL indicates that the job is not running efficiently, perhaps because it is I/O bound or because the job requires more memory than available on the remote workstations. If the job has not (yet) checkpointed, this column contains [??????].
Mb/s
The network usage of this job, in Megabits per second of run-time.

If the -io option is specified, the ST, PRI, SIZE, and CMD columns are replaced with:

READ The total number of bytes the application has read from files and sockets.
WRITE The total number of bytes the application has written to files and sockets.
SEEK The total number of seek operations the application has performed on files.
XPUT The effective throughput (average bytes read and written per second) from the application's point of view.
BUFSIZE The maximum number of bytes to be buffered per file.
BLOCKSIZE The desired block size for large data transfers.

These fields are updated when a job checkpoints or completes. If a job has not yet checkpointed, this information is not available.

If the -cputime option is specified, the RUN_TIME column is replaced with:

CPU_TIME
The remote CPU time accumulated by the job to date (which has been stored in a checkpoint) in days, hours, minutes, and seconds. (If the job is currently running, time accumulated during the current run is not shown. If the job has not checkpointed, this column contains 0+00:00:00.)

The -analyze option may be used to determine why certain jobs are not running by performing an analysis on a per machine basis for each machine in the pool. The reasons may vary among failed constraints, insufficient priority, resource owner preferences and prevention of preemption by the PREEMPTION_REQUIREMENTS expression. If the -long option is specified along with the -analyze option, the reason for failure is displayed on a per machine basis.

Options

-help
Get a brief description of the supported options
-global
Get queues of all the submitters in the system
-submitter submitter
List jobs of specific submitter from all the queues in the pool
-pool centralmanagerhostname[:portnumber]
Use the centralmanagerhostname as the central manager to locate schedds. (The default is the COLLECTOR_HOST specified in the configuration file.
-analyze
Perform an approximate analysis to determine how many resources are available to run the requested jobs
-run
Get information about running jobs.
-hold
Get information about jobs in the hold state. Also displays the time the job was placed into the hold state and the reason why the job was placed in the hold state.
-goodput
Display job goodput statistics.
-io
Display job input/output summaries.
-dag
Display DAG jobs under their DAGMan.
-name name
Show only the job queue of the named schedd
-long
Display job ads in long format
-format fmt attr
Display attribute attr in format fmt. Attributes must be from the job ClassAd.
-cputime
Instead of wall-clock allocation time (RUN_TIME), display remote CPU time accumulated by the job to date in days, hours, minutes, and seconds. (If the job is currently running, time accumulated during the current run is not shown.)
-currentrun
Normally, RUN_TIME contains all the time accumulated during the current run plus all previous runs. If this option is specified, RUN_TIME only displays the time accumulated so far on this current run.
Restriction list
The restriction list may have zero or more items, each of which may be:
cluster
match all jobs belonging to cluster
cluster.proc
match all jobs belonging to cluster with a process number of proc
-constraint expression
match all jobs which match the ClassAd expression constraint
A job matches the restriction list if it matches any restriction in the list Additionally, if owner restrictions are supplied, the job matches the list only if it also matches an owner restriction.

General Remarks

Although -analyze provides a very good first approximation, the analyzer cannot diagnose all possible situations because the analysis is based on instantaneous and local information. Therefore, there are some situations (such as when several submitters are contending for resources, or if the pool is rapidly changing state) which cannot be accurately diagnosed.

-goodput, -cputime, and -io are most useful for STANDARD universe jobs, since they rely on values computed when a job checkpoints.

Examples

The -format option provides a way to specify both the job attributes and formatting of those attributes. The format specification is given as in printf. There must be only one conversion specification per -format option. As an example, to list only Jane Doe's jobs in the queue, choosing to print and format only the owner of the job, the command line arguments for the job, and the process ID of the job:

%condor_q -submitter jdoe -format "%s" Owner -format " %s " Args -format "ProcId = %d\n" ProcId
jdoe 16386 2800 ProcId = 0
jdoe 16386 3000 ProcId = 1
jdoe 16386 3200 ProcId = 2
jdoe 16386 3400 ProcId = 3
jdoe 16386 3600 ProcId = 4
jdoe 16386 4200 ProcId = 7

If only the cluster and process ID of Jane Doe's job's are to be listed, the following example works well.

%condor_q -submitter jdoe -format "%d ." ClusterId -format " %d\n" ProcId
27 . 0
27 . 1
27 . 2
27 . 3
27 . 4
27 . 7

Exit Status

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