NAME¶
jura - Job Usage Reporter of ARC
DESCRIPTION¶
The
jura application is a resource-side accounting (usage logging)
client.
SYNOPSIS¶
jura [
-E exp_time] [
-u url [
-u url
-t topic -u url ...] ]
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
- aggregated Apel accounting records directory
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 1.0 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.
ENVIRONMENT VARIABLES¶
- X509_USER_CERT
- The location of the certificate of the reporting entity, used only if not
specified in job log files. The default is the standard host certificate
location, /etc/grid-security/hostcert.pem.
- X509_USER_KEY
- The location of the private key of the reporting entity, used only if not
specified in job log files. The default is the standard host key location,
/etc/grid-security/hostkey.pem.
- X509_CERT_DIR
- The path to the certificates of trusted CAs, used only if not specified in
job log files. The default is the standard certificates directory,
/etc/grid-security/certificates.
- ARC_LOCATION
- The location where ARC is installed can be specified by this variable. If
not specified the install location will be determined from the path to the
command being executed, and if this fails a WARNING will be given stating
the location which will be used.
- ARC_PLUGIN_PATH
- The location of ARC plugins can be specified by this variable. Multiple
locations can be specified by separating them by : (; in Windows). The
default location is $ARC_LOCATION/lib/arc (\ in Windows).
