Getting the Most Out of GIP Anthony Tiradani tiradani@fnal.gov osg-gip@opensciencegrid.org

Session Outline Questions welcomed and encouraged at any time GIP Topics: ● Checking service health ● GIP Validation ● Add / Alter Attributes Mechanism ● dCache Provider ● Estimated Response Time / Worst Response Time (ERT/WRT) ● How VO's, the GOC, and others view your site ● Other GIP topics?

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

GIP Validation http://home.fnal.gov/~tiradani Critical Tests GIP Reports gLite Reports

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

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: d Cache 1.9 has a new information provider that potentially can be used to query the information.

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

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
