sstat(1)

NAME
sstat - Display the 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: Availability of metrics rely on the jobacct_gather plugin used. For example the jobacct_gather/cgroup in combination with cgroup/v2 does not provide Virtual Memory metrics due to limitations in the kernel cgroups interfaces and will show a 0 for the related fields.

OPTIONS

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

-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.

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

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

-j, --jobs
    Format is <job(.step)>. Stat this job step or comma-separated list of job steps. Jobs may be specified by numeric job ID or by SLUID. This option is required. When no step is specified, only the lowest numbered normal step (excluding batch, extern, etc.) is displayed. Use the --allsteps flag to display all running steps for the given job(s). 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

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

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

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

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

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

--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
Descriptions of each field option can be found below. Note that the Ave*, Max* and Min* accounting fields look at the values for all the tasks of each step in a job and return the average, maximum or minimum values of the task for that job step. For example, for MaxRSS, the returned value is the maximum memory consumption seen by one of the tasks of the step, and MaxRSSTask shows which task it is.

    AllocTRES
        Allocated TRES of all tasks in job.

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

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

    AveDiskRead
        Average number of bytes read by all tasks in job.

    AveDiskWrite
        Average number of bytes written by all tasks in job.

    AvePages
        Average number of page faults of all tasks in job.

    AveRSS
        Average resident set size of all tasks in job.

    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

    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.

    SLUID
        The Slurm Lexicographically-sortable Unique Identifier assigned to the job. This value remains constant during the lifetime of the job, even after a resize. Be aware that the accounting database tracks a separate SLUID per accounting record that changes on resize or requeue.

    TresUsageOutMaxTask

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.

SLURM_DEBUG_FLAGS
    Specify debug flags for sstat to use. See DebugFlags in the slurm.conf(5) man page for a full list of flags. The environment variable takes precedence over the setting in the slurm.conf.

EXAMPLES
