Monthly Availability/Reliability

New weights for the NGIs average A/R values, based on Computation Power

We would like to implement a new way for computing the weights for the NGIs average A/R values, introducing the concept of CE's "computation power":

computation power = hep-spec * LogicalCPUs

This is a quantity that can be addable up over the CEs of a site (and over the sites). Until now it has been simply added up the CEs hep-spec values for getting a site global value, but this is not correct, because the hep-spec refers to a particular CE (to the cluster behind that particular CE) and it is not addable up. That is why, first of all, we asked VAPOR to implement the "computation power" as well as the site/NGI "average hep-spec". Have a look for example at the "figures" section: http://operations-portal.egi.eu/vapor/resources/GL2ResSummary

In the ARGO development instance the new weights have been used for computing the September average A/R values: http://web-egi-devel.argo.grnet.gr/lavoisier/ngi_reports?accept=html

We made a comparison (see the attached file) between the values and the official ones: http://argo.egi.eu/lavoisier/ngi_reports?accept=html

As expected, there were some improvements and some worsening, perhaps more accentuated in the case of NGIs with few sites; take also in mind that with the new way the sites providing more than one CE (either with the same or different hep-spec) weight less than before (in the good and in the evil), because we compute an average hep-spec, not a simple sum over the benchmark values. Moreover several sites are still missing the necessary information for computing the weights in both the methods: please check on VAPOR the values published by your sites in order to properly publishing in the GLUE2 schema the number of logical CPUs and the Hep-Spec06 benchmark.

We would like to move in production this new way starting from November, so if during October many sites fix the information, the new NGIs A/R average values will improve.

Decommissioning EMI WMS

As discussed at the February and April/May OMBs, we are making plans for decommissioning the WMS and moving to DIRAC.

NGIs provided WMS usage statistics, and in general the usage is relatively low, mainly for local testing

Moderate usage by few VOs:

  • NGI_CZ: eli-beams.eu
  • NGI_GRNET: see
  • NGI_IT: calet.org, compchem, theophys, virgo
  • NGI_PL: gaussian, vo.plgrid.pl, vo.nedm.cyfronet
  • NGI_UK: mice, t2k.org

EGI contacted these VOs to agree a smooth migration of their activities to DIRAC, only some of them replied till now:

  • compchem is already testing DIRAC
  • calet.org: discussing with the users the migration to DIRAC. Interested in a webinar on DIRAC.
  • mice: enabled on the GridPP DIRAC server

We need the VO feedback for better defining technical details and timeline:

  • NGIs with VOs using WMS (not necessarily limited to the VOs above), please contact them to ensure that these VOs have a back-up plan.

WMS servers can be decommissioned as soon as the supported VOs do not need them any more. The proposal is:

  • WMS will be removed from production starting from 1st January 2018.
    • VOs have 4 months to find alternatives or migrate to DIRAC
  • Considering that this is not an update, the decommission can be performed in few weeks.

2017-08-21 UPDATE: eli-beams.eu is interested in testing DIRAC; the process for enabling the VO on te DIRAC4EGI server has started.

IPv6 readiness plans

    • Resource Centres: assess the IPv6 readiness of the site infrastructure (real machines, cloud managers)
      • NGIs/ROCs please start discussing with sites and provide suggestions for the overall plan

Decommissioning of dCache 2.10 and 2.13

  • support for the dCache 2.10 ended at December 2016, tickets opened by EGI Operations to track decommissioning
  • dCache 2.13 decommissioning procedure started, in June the probes will get CRITICAL, support from dCache ends in July, upgrades to be performed by August
  • please upgrade to 2.16, whose support ends on May 2018, or to 3.0
    • take care that the dCache team does not support the upgrade from 2.10 directly to 2.16; only 2.10->2.13 and 2.13->2.16 transitions are supported.
  • decommissioning campaign started by EGI Operations http://go.egi.eu/decommdcache213

webdav probes in production

The webdav probes have been deployed in production. Some sites have already enablied the monitoring of their webdav endpoints: CYFRONET-LCG2, egee.irb.hr, GRIF, IGI-BOLOGNA, NCG-INGRID-PT, SARA-MATRIX, UKI-NORTHGRID-LIV-HEP, UNI-BONN.

Several sites are publishing in the BDII the webdav endpoints:

  • AsiaPacific: JP-KEK-CRC-02
  • NGI_AEGIS: AEGIS01-IPB-SCL
  • NGI_CH: UNIGE-DPNC, UNIBE-LHEP
  • NGI_DE: UNI-SIEGEN-HEP
  • NGI_GRNET: GR-01-AUTH, HG-03-AUTH
  • NGI_HR: egee.irb.hr, egee.srce.hr
  • NGI_IBERGRID: CETA-GRID, IFIC-LCG2, NCG-INGRID-PT
  • NGI_FRANCE: GRIF-IPNO, GRIF-LAL, GRIF-LPNHE
  • NGI_IL: IL-TAU-HEP, TECHNION-HEP, WEIZMANN-LCG2
  • NGI_IT: IGI-BOLOGNA, INFN-GENOVA, INFN-MILANO-ATLASC, INFN-ROMA3, INFN-T1
  • NGI_PL: CYFRONET-LCG2, WUT
  • NGI_UK: UKI-NORTHGRID-LIV-HEP, UKI-NORTHGRID-MAN-HEP
  • ROC_CANADA: CA-MCGILL-CLUMEQ-T2

Checked with:

$ ldapsearch -x -LLL -H ldap://egee-bdii.cnaf.infn.it:2170 -b "GLUE2GroupID=grid,o=glue" '(&(objectClass=GLUE2Endpoint)(GLUE2EndpointInterfaceName=webdav))' GLUE2EndpointImplementationName GLUE2EndpointURL

ACTIONS for NGIs and sites: EGI Operations is going to open GGUS tickets asking the sites to enable the monitoring of their webdav endpoints (after verifying that the protocol is really provided).

  • The webdav service endpoint should be registered in GOC-DB for being properly monitored: the nagios probes are executed using the VO ops, so please ensure that the protocol is enabled for ops VO as well
  • the webdav probes are harmless: they are not in any critical profile, they don't raise any alarm in the operations dashboard, and the A/R figures are not affected. We need time and more sites for gathering statistics on their results before making them critical.

For registering on GOC-DB the webdav service endpoint, follow the HOWTO21 in order to filling in the proper information. In particular:

Storage accounting deployment

During the September meeting, OMB has approved the full-scale deployment of storage accounting. The APEL team has tested it with a group of early adopters sites, and the results prove that storage accounting is now production-ready.

Storage accounting is currently supported only for the DPM and dCache storage elements therefore only the resource centres deploying these kind of storage elements are requested to publish storage accounting data.

In order to properly install and configure the storage accounting scripts, please follow the instructions reported in the wiki: https://wiki.egi.eu/wiki/APEL/Storage

After setting up a daily cron job and running the accounting software, look for your data in the Accounting Portal: http://accounting-devel.egi.eu/storage.php. If it does not appear within 24 hours, or there are other errors, please open a GGUS ticket to APEL who will help debug the process.

Please enable on your resources the storage accounting by Oct 30th: after this day, EGI Operations will open a GGUS ticket to all RCs that haven't started the deployment yet.

List of sites already publishing is here.
