Node Fields

Each node in the trace has field attributes.

There are three types of fields:
  1. Boolean fields, which take value in the set (0,1)
  2. Integer fields, which take any 32-bit signed integer value
  3. String fields, which take a null-terminated string value.

The fields are used in the Selection Rules and in Formatting Strings. The field names are not case-sensitive. For example, the rules IsJob and isjob are equivalent.

To get an current list of all fields, use the following:
% vovshow -fields

Incompatible Fields

Some fields make sense only for one type of nodes. For example, the field NAME makes sense for files but not for jobs, while the field COMMAND makes sense for jobs but not for files. A field is considered incompatible for a node if it does not make sense for that node. This notion of incompatible fields is important in the construction of selection rules and formatting strings.

Fields List

Field Name Field Type Applies To Description
AGE Integer (duration) Nodes Age in seconds of a job or of a file.
AGEPP String Nodes Pretty-printed version of age of a job or of a file.
ANNOTATIONS Integer Nodes Number of annotations attached to the node.

CPUPROGRESS Integer (percent) Jobs The percent of CPU time used by a jobs, including all its children, in the last sampling interval. This number can be greater than 100 if the job is running on a multi CPU machine. If CPUPROGRESS is zero, the job is stuck, probably waiting for input or for a license.

FSSUBGROUP String Jobs The part of the FairShare group after the colon.
FSSUSPENDEDCOUNT Integer Jobs The current number of suspended jobs for the FairShare group of the job.
FSTARGET Integer Jobs The FairShare target for the FairShare group to which the job belongs. The target, which is normally a fracsional number less than 1.0, is multiplied by 10,000 to yield the FSTARGET. For example, a group that has a target of 30%=0.3 will have a FSTARGET of 3,000.

LMRESOURCES String JOBS These are the license resources (typically derived from FLEXlm features) that appear to be used by a job even if the job does not explicitly declare them. This field is used by vovlmremove to decide which features to remove. The field is updated based on the matching of free FLEXlm handles and running jobs. The field consists of an even number of words, with each pair consisting of a resource name and a boolean flag indicating if the resource is a "false-out-of-queue", i.e. the handle is not-requested but used. A handle is Example: License:a#2 0 License:b#1 1 This means that the job requested 2 tokens of License:a and is in fact using them. In addition, the job is using 1 token of License:b even if it does not request it. See also LM_HANDLES_ALL and LM_HANDLES_NRU.
LX String JOBS Legal Exit Value for a job (Same as legalexit and ok_status).

REQPERCENT Integer JOBS Requested PERCENT for the job. See also explanation on REQRAM.
REQRAM Integer (MB) JOBS RAM requested by a job. This value may come from 1) the SOLUTION property on the job, if it exists, 2) from the requested resource on the bucket, if the job is queued, or 2) from the resources string of the job. Normally, the value is the same regardless of the origin, but it is possible and acceptable that the value may change due to additional math performed during scheduling. Normal case: a job requests "RAM/200". Then the REQRAM value is going to be 200. Strange case: a job requests "RAM/200 SLOTS/2 RAM/300" (i.e. the RAM request is repeated). In this case, REQRAM will be 200 for the job if it is not Queued or if the SOLUTION property is removed after the execution of the job. Else it will be 500 (=200+300) while the job is Queued.
REQSLOTS Integer JOBS Requested number of slots for the job. See also explanation on REQRAM.
