reporting — Sun Grid Engine reporting file format

Description

A Sun Grid Engine system writes a reporting file to $SGE_ROOT/default/common/reporting. The reporting file contains data that can be used for accounting, monitoring and analysis purposes. It contains information about the cluster (hosts, queues, load values, consumables, etc.), about the jobs running in the cluster and about sharetree configuration and usage. All information is time related, events are dumped to the reporting file in a configurable interval. It allows to monitor a "real time" status of the cluster as well as historical analysis.

Format

The reporting file is an ASCII file. Each line contains one record, and the fields of a record are separated by a delimiter (:). The reporting file contains records of different type. Each record type has a specific record structure.

The first two fields are common to all reporting records:

time
Time (GMT unix timestamp) when the record was created.
record type
Type of the accounting record. The different types of records and their structure are described in the following text.

new_job

The new_job record is written whenever a new job enters the system (usually by a submitting command). It has the following fields:

submission_time
Time (GMT unix time stamp) when the job was submitted.
job_number
The job number.
task_number
The array task id. Always has the value -1 for new_job records (as we don't have array tasks yet).
pe_taskid
The task id of parallel tasks. Always has the value "none" for new_job records.
job_name
The job name (from -N submission option)
owner
The job owner.
group
The unix group of the job owner.
project
The project the job is running in.
department
The department the job owner is in.
account
The account string specified for the job (from -A submission option).
priority
The job priority (from -p submission option).

job_log

The job_log record is written whenever a job, an array task or a pe tasks is changing status. A status change can be the transition from pending to running, but can also be triggered by user actions like suspension of a job. It has the following fields:

event_time
Time (GMT unix time stamp) when the event was generated.
event
A one word description of the event.
job_number
The job number.
task_number
The array task id. Always has the value -1 for new_job records (as we don't have array tasks yet).
pe_taskid
The task id of parallel tasks. Always has the value "none" for new_job records.
state
The state of the job after the event was processed.
user
The user who initiated the event (or special usernames "qmaster", "scheduler" and "execd" for actions of the system itself like scheduling jobs, executing jobs etc.).
host
The host from which the action was initiated (e.g. the submit host, the qmaster host, etc.).
state_time
Reserved field for later use.
submission_time
Time (GMT unix time stamp) when the job was submitted.
job_name
The job name (from -N submission option)
owner
The job owner.
group
The unix group of the job owner.
project
The project the job is running in.
department
The department the job owner is in.
account
The account string specified for the job (from -A submission option).
priority
The job priority (from -p submission option).
message
A message describing the reported action.

acct

Records of type acct are accounting records. Normally, they are written whenever a job, a task of an array job, or the task of a parallel job terminates. However, for long running jobs an intermediate acct record is created once a day after a midnight. This results in multiple accounting records for a particular job and allows for a fine-grained resource usage monitoring over time. Accounting records comprise the following fields:

qname
Name of the cluster queue in which the job has run.
hostname
Name of the execution host.
group
The effective group id of the job owner when executing the job.
owner
Owner of the Sun Grid Engine job.
job_name
Job name.
job_number
Job identifier - job number.
account
An account string as specified by the qsub(1) or qalter(1) -A option.
priority
Priority value assigned to the job corresponding to the priority parameter in the queue configuration (see queue_conf(5)).
submission_time
Submission time (GMT unix time stamp).
start_time
Start time (GMT unix time stamp).
end_time
End time (GMT unix time stamp).
failed
Indicates the problem which occurred in case a job could not be started on the execution host (e.g. because the owner of the job did not have a valid account on that machine). If Sun Grid Engine tries to start a job multiple times, this may lead to multiple entries in the accounting file corresponding to the same job ID.
exit_status
Exit status of the job script (or Sun Grid Engine specific status in case of certain error conditions).
ru_wallclock
Difference between end_time and start_time (see above).

The remainder of the accounting entries follows the contents of the standard UNIX rusage structure as described in getrusage(2). Depending on the operating system where the job was executed some of the fields may be 0. The following entries are provided:

ru_utime
ru_stime
ru_maxrss
ru_ixrss
ru_ismrss
ru_idrss
ru_isrss
ru_minflt
ru_majflt
ru_nswap
ru_inblock
ru_oublock
ru_msgsnd
ru_msgrcv
ru_nsignals
ru_nvcsw
ru_nivcsw
project
The project which was assigned to the job.
department
The department which was assigned to the job.
granted_pe
The parallel environment which was selected for that job.
slots
The number of slots which were dispatched to the job by the scheduler.
task_number
Array job task index number.
cpu
The cpu time usage in seconds.
mem
The integral memory usage in Gbytes seconds.
io
The amount of data transferred in input/output operations.
category
A string specifying the job category.
iow
The io wait time in seconds.
pe_taskid
If this identifier is set the task was part of a parallel job and was passed to Sun Grid Engine via the qrsh -inherit interface.
maxvmem
The maximum vmem size in bytes.
arid
Advance reservation identifier. If the job used resources of an advance reservation then this field contains a positive integer identifier otherwise the value is "0" .

queue

Records of type queue contain state information for queues (queue instances). A queue record has the following fields:

qname
The cluster queue name.
hostname
The hostname of a specific queue instance.
report_time
The time (GMT unix time stamp) when a state change was triggered.
state
The new queue state.

The cluster queue name.
hostname
The hostname of a specific queue instance.
report_time
The time (GMT unix time stamp) when a state change was triggered.
state
The new queue state.
consumables
Description of consumable values. Information about multiple consumables is separated by space. A consumable description has the format <name>=<actual_value>=<configured value>.

host

A host record contains information about hosts and host load values. It contains the following information:

sharelog

The Sun Grid Engine qmaster can dump information about sharetree configuration and use to the reporting file. The parameter sharelog sets an interval in which sharetree information will be dumped. It is set in the format HH:MM:SS. A value of 00:00:00 configures qmaster not to dump sharetree information. Intervals of several minutes up to hours are sensible values for this parameter.
