sstat(1)

NAME
sstat - Display various status information of a running job/step.

SYNOPSIS
sstat [OPTIONS...]

DESCRIPTION

Status information for running jobs invoked with Slurm.

The sstat command displays job status information for your analysis. The sstat command displays information pertaining to CPU, Task, Node, Resident Set Size (RSS) and Virtual Memory (VM). You can tailor the output with the use of the --fields= option to specify the fields to be shown.

For the root user, the sstat command displays job status data for any job running on the system.

For the non-root user, the sstat output is limited to the user's jobs.

NOTE: The sstat command requires that the jobacct_gather plugin be installed and operational.

NOTE: The sstat command is not supported on Cray ALPS.

-a, --allsteps
    Print all steps for the given job(s) when no step is specified.

-e, --helpformat
    Print a list of fields that can be specified with the '--format' option.

-h, --help
    Displays a general help message.

-i, --pidformat
    Predefined format to list the pids running for each job step. (JobId,Nodes,Pids)

-j, --jobs
    Format is <job(.step)>. Stat this job step or comma-separated list of job steps. This option is required. The step portion will default to the lowest numbered (not batch, extern, etc) step running if not specified, unless the --allsteps flag is set where not specifying a step will result in all running steps to be displayed. NOTE: A step id of 'batch' will display the information about the batch step. NOTE: A step id of 'extern' will display the information about the extern step. This step is only available when using PrologFlags=contain

-n, --noheader
    No heading will be added to the output. The default action is to display a header.

--noconvert
    Don't convert units from their original type (e.g. 2048M won't be converted to 2G).

-o, --format, --fields
    Comma separated list of fields. (use '--helpformat' for a list of available fields). NOTE: When using the format option for listing various fields you can put a %NUMBER afterwards to specify how many characters should be printed. i.e. format=name%30 will print 30 characters of field name right justified. A -30 will print 30 characters left justified.

-p, --parsable
    output will be '|' delimited with a '|' at the end

-P, --parsable2
    output will be '|' delimited without a '|' at the end

--usage
    Display a command usage summary.

-v, --verbose
    Primarily for debugging purposes, report the state of various variables during processing.

-V, --version
    Print version.

  Job Status Fields
The following are the field options:

    AveCPU
        Average (system + user) CPU time of all tasks in job.

    AveCPUFreq
        Average weighted CPU frequency of all tasks in job, in kHz.

    AveVMSize
        Average Virtual Memory size of all tasks in job.

    ConsumedEnergy
        Total energy consumed by all tasks in job, in joules. Note: Only in case of exclusive job allocation this value reflects the jobs' real energy consumption.

    JobID
        The number of the job or job step. It is in the form: job.jobstep .

    MaxDiskRead
        Maximum number of bytes read by all tasks in job.

    MaxDiskReadNode
        The node on which the maxdiskread occurred.

    MaxDiskReadTask
        The task ID where the maxdiskread occurred.

    MaxDiskWrite
        Maximum number of bytes written by all tasks in job.

    MaxDiskWriteNode
        The node on which the maxdiskwrite occurred.

    MaxDiskWriteTask
        The task ID where the maxdiskwrite occurred.

    MaxPages
        Maximum number of page faults of all tasks in job.

    MaxPagesNode
        The node on which the maxpages occurred.

    MaxPagesTask
        The task ID where the maxpages occurred.

    MaxRSS
        Maximum resident set size of all tasks in job.

    MaxRSSNode
        The node on which the maxrss occurred.

    MaxRSSTask
        The task ID where the maxrss occurred.

    MaxVMSize
        Maximum Virtual Memory size of all tasks in job.

    MaxVMSizeNode
        The node on which the maxvsize occurred.

    MaxVMSizeTask
        The task ID where the maxvsize occurred.

    MinCPU
        Minimum (system + user) CPU time of all tasks in job.

    MinCPUNode
        The node on which the mincpu occurred.

    MinCPUTask
        The task ID where the mincpu occurred.

    NTasks
        Total number of tasks in a job or step.

    ReqCPUFreq
        Requested CPU frequency for the step, in kHz.

    TresUsageInAve
        Tres average usage in by all tasks in job. NOTE: If corresponding TresUsageInMaxTask is -1 the metric is node centric instead of task.

    TresUsageInMax
        Tres maximum usage in by all tasks in job. NOTE: If corresponding TresUsageInMaxTask is -1 the metric is node centric instead of task.

    TresUsageInMaxNode

    TresUsageOutMaxNode
        Node for which each maximum TRES usage out occurred.

    TresUsageOutMaxTask
        Task for which each maximum TRES usage out occurred.

PERFORMANCE

Executing sstat sends a remote procedure call to slurmctld. If enough calls from sstat or other Slurm client commands that send remote procedure calls to the slurmctld daemon come in at once, it can result in a degradation of performance of the slurmctld daemon, possibly resulting in a denial of service.

Do not run sstat or other Slurm client commands that send remote procedure calls to slurmctld from loops in shell scripts or other programs. Ensure that programs limit calls to sstat to the minimum necessary for the information you are trying to gather.

ENVIRONMENT VARIABLES

Some sstat options may be set via environment variables. These environment variables, along with their corresponding options, are listed below. (Note: Command line options will always override these settings.)

SLURM_CONF
    The location of the Slurm configuration file.

EXAMPLES

Display job step information for job 11 with the specified fields:
