NAME¶

jura - Job Usage Reporter of ARC

DESCRIPTION¶

The jura application is a resource-side accounting (usage logging) client.

SYNOPSIS¶

jura [-E exp_time] [-L] [-u url [-u url -t topic -u url ...] ] [-r time_range] ctrl_dir [ctrl_dir ...]

OPTIONS¶

-E

expiration time (validity length) of job log files in days

-u

logging destination URL

-t

topic for a destination URL

-o

archived accounting records directory

-L

turns on timestamps and logging level in messages printed during execution

time range of archived messages that will be resend

-v

ARGUMENTS¶

ctrl_dir

The A-REX control directory for a mapped local UNIX user

EXTENDED DESCRIPTION¶

Normally, jura is invoked by A-REX periodically with the appropriate command line arguments, but it can also be executed interactively.

Job log files, i.e. files produced by A-REX for each job and stored under <ctrl_dir>/logs contain various usage data and configuration options for accounting (see NORDUGRID-TECH-24 for details of their content). These files are parsed by jura, converted into UR format, and submitted in batches to reporting destinations. A destination is a resource usage logging service; currently SGAS LUTS and CAR 1.2 message propagation are supported. Job log files older than the expiration time specified with the -E option are deleted without parsing.

If the -u option is absent, URs are submitted to the destination URLs specified in the job log files. If submitting succeeds, the corresponding job log files are deleted. This is the default, automatic mode of operation.

If destination URLs are specified with the -u option, URs are submitted only to these destinations (one UR per job to each destination). In this case, job log files are preserved even if submitting succeeds.

If the -r option is absent, <ctrl_dir> parameter be using as location of archived files, URs from the given directory are submitted to the destination URLs specified with -u option in the CLI.
