reporting − Grid Engine reporting file format
A Grid Engine system writes a reporting file $SGE_ROOT/$SGE_CELL/common/reporting if reporting=true is specified in the sge_conf(5) reporting_params. This occurs intervals of the flush_time specified in the same place. 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 and events are dumped to the reporting file in a configurable interval. It allows "real time" monitoring of the cluster status as well as historical analysis.
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 |
The time when the record was created. All time values described here are the number of seconds since the Unix epoch (1970-01-01 00:00:00 UTC). |
record type
Type of the accounting record.
The different types of records and their structure are described below, eliding the leading time and record type fields in each case.
new_job
The new_job record is written whenever a new job enters the system (usually by a submission command). It has the following fields:
submission_time
Time 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 array tasks haven’t been created at that stage).
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 the −A submission option).
priority
The job priority (from the −p submission option).
job_log
If joblog=true is specified in the sge_conf(5) reporting_params, a job_log record is written whenever a job, an array task or a PE task changes 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 when the event was generated.
|
event |
A one word description of the event. |
job_number
The job number.
task_number
The PE task id. Always has the value −1 for new_job records (as parallel tasks haven’t been created at that stage).
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 when the job was submitted.
job_name
The job name (from the −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 the −A submission option).
priority
The job priority (from the −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 a task of a parallel job terminates. However, for long running jobs an intermediate acct record is created once a day after midnight. This results in multiple accounting records for a particular job and allows for fine-grained resource usage monitoring over time.
Accounting records have the structure described in accounting(5), with the addition of leading time and type fields (which are not used in the accounting file).
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 when a state change was triggered.
|
state |
The new queue state. The possible states are single-letter values, as reported by qhost(1) with the −q option. |
queue_consumable
A queue_consumable record contains information about queue consumable values in addition to queue state information:
|
qname |
The cluster queue name. |
hostname
The hostname of a specific queue instance.
report_time
The time 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.
Consumables are only logged if log_consumables=true is specified in the sge_conf(5) reporting_params, or the consumable is specified in the local or global host_conf(5) report_variables.
host
A host record contains information about hosts and host load values. It contains the following information:
hostname
The name of the host.
report_time
The time when the reported information was generated.
|
state |
The new host state. Currently, Grid Engine doesn’t track a host state; the field is reserved for future use. Always contains the value X. |
load values
Description of load values. Information about multiple load values is separated by space. A load value description has the format name=actual_value.
host_consumable
A host_consumable record contains information about hosts and host consumables. Host consumables can, for example, be licenses. It contains the following information:
hostname
The name of the host.
report_time
The time when the reported information was generated.
|
state |
The new host state. Currently, Grid Engine doesn’t track a host state; the field is reserved for future use. Always contains the value X. |
consumables
Description of consumable values. Information about multiple consumables is separated by space. A consumable description has the format name=actual_value=configured_value.
Consumables are only logged if log_consumables=true is specified in the sge_conf(5) reporting_params, or the consumable is specified in the local or global host_conf(5) report_variables.
sharelog
The Grid Engine qmaster can dump information about sharetree configuration and use to the reporting file. The sge_conf(5) reporting_params can specify sharelog, which 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. The record contains the following fields
current time
The present time
usage time
The time used so far
node name
The node name
user name
The user name
project name
The project name
|
shares |
The total shares |
job count
The job count
|
level |
The percentage of shares used |
|||
|
total |
The adjusted percentage of shares used |
long target share
The long target percentage of resource shares used
short target share

|||
|
cpu |
The number of CPU seconds used |
|||
|
mem |
The time integral of memory used (in GB seconds) |
