4 HGSM/GOCDB (1) Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

5 HGSM/GOCDB (2) Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

6 HGSM/GOCDB (3) Static database containing all relevant data about all SEE-GRID and AEGIS sites Must be kept synchronized with the real situation All sheets must be properly updated Site Info Contacts Site Nodes Downtimes XML dumps the easiest way to apply changes is to download XML dump of the data, edit it appropriately, and then upload the new XML file; this also allows keeping of backups Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

7 HGSM/GOCDB (4) The essential fields in HGSM: GIIS URL Monitoring: Yes Status: certified Type: seegrid_production, seegrid_certified, egee_production Site Commitments Contacts and administrators All fields have to have correct values!

9 Helpdesk/GGUS (2) Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

10 Helpdesk/GGUS (3) Central reference point for tracking of all operational and user problems Identified problems are reported through the Helpdesk and assigned to the appropriate supported If problems cannot be solved within the SEE-GRID community, they are propagated to other projects/ initiatives/support systems (e.g. GGUS) URL: Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

11 BBmSAM/SAM Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

12 BBmSAM History Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

13 BBmSAM Portal that provides access to the database of SAM tests results Central tools for identification of operational problems Should be checked by each site admin on a daily basis Should be used to troubleshoot problems Also provides SLA figures URL: Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

14 GStat (1) Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

15 GStat (2) Central tool for monitoring of the information system of SEE-GRID infrastructure Provides useful data Identifies problems with sites Should be checked by each site admin on a daily basis and used for troubleshooting Useful ldapsearch commands can be found on GStat pages! URL: Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

16 Nagios/CIC portal (1) Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

17 Nagios/CIC portal (2) Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

18 Nagios/CIC portal (3) Collection of alarms raised by various tools The aim is to integrate all the tools and make the life of site admins and infrastructure managers easier In the future, automatic creation of Helpdesk tickets will be implemented URL: Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

19 Accounting portal (1) Accounting by site Accounting by countries and institutions Accounting by applications Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

20 EGEE Accounting portal Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

21 Accounting portal (2) Collects the accounting data from all SEE-GRID and AEGIS sites through apel accounting publisher developed by the project Provides aggregated accounting data by site, country, institution, application Each site must publish the accounting data properly URL: Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

22 Downtime procedures Downtimes must be announced well in advance (1 week is reasonable time) There are always downtime due to hardware etc. failures that cannot be anticipated All downtimes must be entered properly in HGSM That way they are not be counted against the site s availability In addition, all downtimes must be broadcasted by e- mail to the GIM, APP and proper VO mailing lists Downtime should not exceed 10% of the total time (monthly, quarterly) If yes, explanation must be provided If the explanation is not accepted by the project management, SA1 claims will be rejected Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

23 Upgrade procedures All upgrades/updates are announced over the GIM list The broadcasts contain links to further instructions for upgrades for each Grid service Site admins should carefully examine them before performing the update! In addition, possible SEE-GRID-specific instructions are given in the For especially important updates/changes, tickets are created for each site For some upgrades/updates to be performed, downtimes may be required OS updates must be regularly installed, to minimize security risks Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

24 Grid-Operator-On-Duty (GOOD) Rotating shifts on a weekly basis Each country s GIM is responsible to monitor sites during his/ her shift Tickets are submitted to sites with problems, according to the status of sites in various monitoring tools (BBmSAM, GStat, Nagios, Accounting portal, etc.) Older tickets that are not resolved are escalated Support is given to sites that cannot resolve earlier identified operational problems User tickets are assigned to the appropriate supporters Wiki documentation is updated, or new wiki pages created if necessary URLs: Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

25 Usual problems and links to (possible) solutions BDII sitebdii (GIIS) or top-level BDII is Unreachable CA No info published CA version test failed with error message: This CA is an old one and time allowed to upgrade is over CE (Computing Element) Job submission failed with error message: Brokerhelper: Cannot plan. No compatible resources: Job submission failed with error message: Got a job held event, reason: Unspecified gridmanager error Job submission failed with error message: Cannot read JobWrapper output, both from Condor and from Maradona Job submission failed with error message: 7 authentication failed Job submission failed with error message: 10 data transfer to the server failed Waiting jobs in the GRIS SE (Storage Element) File copy and registration failed with error message: FTPD GSSAPI error: GSS Major Status: General failure %3A_General_failure Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,

26 Service Level Agreement (SLA) Old URL: The change to the current one is that the required availability is 80%, and that the availability is calculated on 3h basis, not on a daily basis BBmSAM portal provides SLA figures Sites not fully conforming to the SLA will have reduced funding Sites with the availability <50% will be uncertified Sites fully conforming to the SLA will be put into seegrid_certified status and become visible to the whole SEE region (i.e. not only SEE-GRID, but also EGEE-SEE etc.) Regional SEE-GRID-SCI Training for Site Administrators, Institute of Physics Belgrade, March 5-6,
