MB Older Actions

  • A.Aimar will ask information about the CERN reliability data during the power cut.

When CERN was down, no new SAM tests were run. This can be seen for CERN in gridview[1], where there is a large gap that day from 03:22:55 to 30/05/2008 14:49:53.

The last test CERN had (at 3:22) was GREEN, so during the whole period, it was considered GREEN by Gridview – thus availability was 100%

After the fact, two downtimes were entered for CERN : 06:36-08:00 and another from 08:13-10:00. Gridview only takes into consideration downtimes entered 2 hours BEFORE an intervention. Therefore, reliability was 100%.

  • H.Marten and Y.Schutz agreed to verify and re-derive the correct data and the normalization factors applied (at FZK for instance). And compare the local accounting, APEL WLCG accounting and the ALICE MonALIsa accounting.


  • 30 Apr 2008 - Sites send to H.Renshall plans for the 2008 installations and what will be installed for May and when the full capacity for 2008 will be in place.

The issue was discussed at the LHCC mini review and J.Gordon received the updated information. J.Gordon will pass the information to H.Renshall.

  • 1 June 2008 - J.Templon will summarize the proposal of the interim solution for treating Operations Alarms until a GGUS-based solution is available.


  • 31 May 2008 - OSG Tier-2 should report availability and reliability data into SAM and GOCDB; so that the monthly Tier-2 report can include their information.

To remove, New milestones have been already added to the HL Milestones dashboard.

Done. The agenda above is considered accepted.

  • 16 May 2008 - I.Bird should ask information to CERN about the plans of the Accelerator for 2009.

  • 24 May 2008 - A.Aimar will set up a page for the site operations alerts.
Update: The page for Operations Alarms is here: https://twiki.cern.ch/twiki/bin/view/LCG/OperationsAlarmsPage

  • 18 May 2008 - Sites should send the emails address where they are going to receive operations alarms. Sites should confirm that they can achieve this.

Obsolete. Replaced by the “Operations Alarms Page” action.

A new page for alert emails for the sites, not the same as the contact pages. This is a separate page to be prepared. Is not the same and the contact page already prepared (https://twiki.cern.ch/twiki/bin/view/LCG/TierOneContactDetails). Should be a different list only for alerts and only for a few people from the Experiments. OperationsAlarms

  • 31 March 2008 - ALICE, ATLAS and CMS should provide the read and write rates that they expect to reach. In terms of clear values (MB/sec, files/sec, etc) including all phases of processing and re-processing.

Not Done. Next week we will close this item and address specific issues in the future. It was agreed that the Experiments provide the same information in the format used by LHCb

Here is the example from LHCb: https://twiki.cern.ch/twiki/pub/LCG/GSSDLHCB/Dataflows.pdf

  • 31 March 2008 - OSG should prepare site monitoring tests equivalent to those included in the SAM testing suite.
    J.Templon and D.Collados will verify this equivalence and report to the MB as it was done for NDGF.

Done in the previous MB meeting. The OSG tests are described here: http://rsv.grid.iu.edu/documentation/help/.

The proposed new list of critical tests is available here: https://twiki.cern.ch/twiki/bin/view/LCG/OSGCriticalProbes#Proposed_Critical_Probes_for_OSG

  • 6 May 2008 - Sites should confirm to the MB that they will define an email digitally signed (?) for their alarm system submission.

Replaced by the action to fill in the wiki page.

  • 16 May 2008 - Each Experiment proposes 4 users who can raise alarms at the sites and are allowed to mail to the sites alarm mailing list.

Replaced by the action to fill in the wiki page.

  • 9 May 2008 - Sites should send comments about the New HL Milestones.

  • 18 Mar 2008 - Sites should propose new tape efficiency metrics that they can implement, in case they cannot provide the metrics proposed.

Done. The sites that cannot implement the metrics have reported to the reasons and a HL milestone is introduced to track the situation. Here is the link to the wiki page: https://cern.ch/twiki/bin/view/LCG/MssEfficiency

FZK: H.Marten explained that those metrics at FZK still need to be implemented and will not be ready for CCRC08-May. They could publish other metrics in the wiki page but he would first make sure that the data is correct.
ASGC: Have received the scripts from CERN in order to extract the metrics from their CASTOR installation. They still have to modify them in order to make them work with their specific setup.
IN2P3 was not present but F.Hernandez sent an email after the meeting:FR-CCIN2P3 is one of the sites not yet publishing this information. For your information, we are currently collecting the data for extracting the proposed metrics as closely as possible. The work on the tools to automate the extraction of the relevant information and generation of the metrics was more time-consuming than what we initially anticipated. We expect to have this initial phase finished by the end of this week and start publishing the available data in the wiki by the end of next week.

  • 18 April 2008 - I.Bird and A.Aimar will propose new milestones to the Management Board.

First proposal on the 29.4.2008. WIll be discussed at the F2F MB.

Done. The US Tier-2 sites have not available “n/a” instead of the 0% as before.

  • 18 Apr 2008 - M.Ernst should clarify the situation with the ATLAS sites that are not providing and SRM interface. And how availability reliability is reported.

Done. M.Ernst explained that there is the commitment of all US ATLAS sites to have an SRM interface by and of May 2008.

  • 29 Feb 2008 - A.Aimar will verify why the reliability values for the Tier-2 sites seems incorrect (being lower than availability).

Done. Reliability is lower than availability because availability was considering the “unknown” status as “available” in order not to penalize the sites when SAM has problems. The algorithm is going to be modified to fix this inconsistency. For the availability calculations if “unknown” is between “downtime” periods it will be considered “unknown = downtime” and not “unknown = available”.


  • 26 Feb 2008 - Discuss/agree on a milestone about providing tape efficiency metrics should be introduced for the Tier1-s sites, before CCRC08 in May.

Done. The MB Members agreed that a milestone should be added in order to have metrics about tape efficiency at all Tier-1 sites. In order to be ready for the CCRC08-May the metrics should be in place by end of April 2008. The metrics to produce are the ones in the Tape Efficiency Wiki or equivalent. If sites can provide more metrics is even better.
