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

Since Dec 1st it has been used the CE's "computation power" for computing the weights for the NGIs average A/R values:

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

Several sites are still missing the necessary information for computing the weights: 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.

Next year we are going to open tickets for making the sites either publish or fixing the necessary information.

Decommissioning EMI WMS

WMS servers can be decommissioned. Please follow the procedure PROC12. The plan is:

WMS servers in downtime on GOC-DB

VOs have to find alternatives or migrate to DIRAC:

IPv6 readiness plans

webdav probes in production

The webdav probes have been deployed in production. Several sites publish the webdav protocol in the BDII: they have been asked to register the endpoint on GOC-DB and to enable the monitoring, if it wasn't already done.

List of sites that not have completed the configuration yet:

List of sites that disabled webdav: UNIGE-DPNC, GR-01-AUTH, HG-03-AUTH, CETA-GRID, WUT

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

During the January OMB we are going to discuss the inclusion of the probes in the operators and in the critical profile:

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

IMPORTANT: be sure to have installed the star-accounting.py script v1.0.4 (http://svnweb.cern.ch/world/wsvn/lcgdm/lcg-dm/trunk/scripts/StAR-accounting/star-accounting.py)

After setting up a daily cron job and running the accounting software, look for your data in the Accounting Portal: http://goc-accounting.grid-support.ac.uk/storagetest/storagesitesystems.html. 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.

List of sites already publishing and of tickets opened is reported here.

PROBLEM: several (DPM) sites are using an old version of the star-accounting.py script. This leads to records having an EndTime 30 days in the future. The star-accounting.py script version to use is v1.0.4 (http://svnweb.cern.ch/world/wsvn/lcgdm/lcg-dm/trunk/scripts/StAR-accounting/star-accounting.py).

The APEL team opened tickets for this issue:

PROBLEM number 2: the APEL repository is receiving an increasing number of storage records that have been encrypted with something that isn’t the APEL certificate, so the records can’t be read them (and so the sender is unknown). If your site isn’t successfully publishing, please comment out the “server_cert” variable in sender.cfg
