SLIDE 3

GIP Service Health

Check GIP reports (more on that later)

http://home.fnal.gov/~tiradani

Check BDII web pages

http://is.grid.iu.edu/cgi-bin/status.cgi

Check CEMon logs

OSG 0.8.0: $VDT_LOCATION/tomcat/v5/logs/glite-ce-monitor.log OSG 1.0.0 $VDT_LOCATION/glite/var/log/glite-ce-monitor.log

Check that CEMon (tomcat) is running

ps -ef | grep java

Add / Alter Attributes

Altering Attributes:

$VDT_LOCATION/gip/etc/alter-attributes.conf

Adding Attributes:

$VDT_LOCATION/gip/etc/add-attributes.conf In both cases, specify the dn desired and the attributes. Example(alter-attributes.conf):

dn: GlueCEUniqueID=grow-test1.its.uiowa.edu,:2119/jobmanager-condor-osg,mds-vo-name=local,o=grid GlueCEPolicyMaxRunningJobs: 100 GlueCEPolicyMaxWaitingJobs: 50 https://twiki.grid.iu.edu/bin/view/ReleaseDocumentation/GipOverrides#Case_1_Altering_values_published

SLIDE 6

dCache Provider

Current state:

https://twiki.grid.iu.edu/bin/view/InformationServices/DcacheGip

Intermediate state:

All information is queried from the admin interface. This removes the database connection dependency.

Future state: dCache 1.9 has a new information provider that

potentially can be used to query the information.

SLIDE 7

ERT / WRT

Will be released with GIP 1.0.5 If you want it right now, need to get from SVN -

* https://twiki.grid.iu.edu/twiki/bin/view/InformationServices/WebHome * Put in $VDT_LOCATION/gip/plugins/ert_update.py

Changes the site rankings for jobs originating from the LCG WMS. Administrator overrides (gip.conf settings): average_job_time, max_job_time

SLIDE 8

Site Views

GOC does not monitor GIP content, nor does it monitor the GIP service directly. Brian Bockelman monitors the information in the GIP for some VO's You should monitor your own site European (LCG/EGEE) users use the glite UI to see your site. (see the GIP reports for examples) All VO's see your site through the BDII or RESS
