checkjob | (Check Job) |
Synopsis
checkjob [-A] [-l policylevel] [-n nodeid] [-q qosid] [-r reservationid] [-v] [--flags=future] jobid
Overview
checkjob displays detailed job state information and diagnostic output for a specified job. Detailed information is available for queued, blocked, active, and recently completed jobs.Access
This command can be run by level 1-3 Moab administrators for any job. Also, end users can use checkjob to view the status of their own jobs.Arguments
| -A (Attribute-Value pair) | |
| Format: | |
| Default: | --- |
| Description: | Provides output in the form of parsable Attribute-Value pairs. |
| Example: | > checkjob -A 6235 Moab will display job information in the following format: <ATTRIBUTE>=<VALUE>;. |
| --flags | |
| Format: | --flags=future |
| Default: | --- |
| Description: | Evaluates future eligibility of job (ignore current resource state and usage limitations). |
| Example: | > checkjob -v --flags=future 6235 Display reasons why idle job is blocked ignoring node state and current node utilization constraints. |
| -h (Help) | |

| Example: | > checkjob -v 6235 |
Details
This command allows any Moab administrator to check the detailed status and resource requirements of a active, queued, or recently completed job. Additionally, this command performs numerous diagnostic checks and determines if and where the job could potentially run. Diagnostic checks include policy violations, reservation constraints, preemption status, and job to resource mapping. If a job cannot run, a text reason is provided along with a summary of how many nodes are and are not available. If the -v flag is specified, a node by node summary of resource availability will be displayed for idle jobs.Job Eligibility
If a job cannot run, a text reason is provided along with a summary of how many nodes are and are not available. If the -v flag is specified, a node by node summary of resource availability will be displayed for idle jobs. For job level eligibility issues, one of the following reasons will be given:
| Reason | Description |
|---|---|
| job has hold in place | one or more job holds are currently in place |
| insufficient idle procs | there are currently not adequate processor resources available to start the job |
| idle procs do not meet requirements | adequate idle processors are available but these do not meet job requirements |
| start date not reached | job has specified a minimum start date which is still in the future |
| expected state is not idle | job is in an unexpected state |
| state is not idle | job is not in the idle state |
| dependency is not met | job depends on another job reaching a certain state |
| rejected by policy | job start is prevented by a throttling policy |
If a job cannot run on a particular node, one of
the following 'per node' reasons will be given:
| Class | Node does not allow required job class/queue |
| CPU | Node does not possess required processors |
| Disk | Node does not possess required local disk |
| Features | Node does not possess required node features |
| Memory | Node does not possess required real memory |
| Network | Node does not possess required network interface |
| State | Node is not Idle or Running |
Reservation Access
The -r flag can be used to provide detailed information about job access to a specific reservation
If a job is marked as a preemptor and the -v and -n flags are specified, checkjob will perform a job by job analysis for all jobs on the specified node to determine if they can be preempted.

The example job cannot be started for two different reasons.
