• There was a brief power outage at the RAL site on Monday 20th November. Most services have now recovered.
• The FTS service (both instances) is experiencing problems which are not fully understood.
• The database behind the FTS-production instance is being updated today.
• Re-distribution of data in Echo onto the 2015 capacity hardware is now complete. There are now 8PBytes of usable space in Echo. However, there is some data re-balancing to be done before upping the quotas so the VOs can make use of the extra space.
• Castor was be unavailable for a few hours on Tuesday 14th Nov for patching of the nodes.
• The LHCb Castor SRMs were successfully updated on Wednesday 15th Nov. This new version (2.1.16-18) respects the user-specified bringOnline timeout rather than ignoring it and defaulting to 4 hours. It is planned to upgrade the other SRMs on Tuesday 5th December.
• Both Production and Test FTS services have IPv6 enabled (i.e. are now dual-stack).

Wed 15 Nov

• More xcache progress at some sites; less at others who may be blocking on dependencies or be busy with Other Things(tm)
• Some interest in following the non-X.509 authentication/authorisation

Wed 08 Nov

• Not (very) modest at all progress on xcache testing... from Chris at RALPP

Wed 01 Nov

• (very) modest progress on xcache testing...
• Except that RALPP has it fully working for dCache - hope to get full report next week

Tuesday 3rd October

• Looking for small DPM ATLAS site to possibly test xrootd caching
• Tracking upgrade of SEs to new what will be new baseline versions. (dCache sites updated; 6/14 DPM up-to-date)
• Alastair D. to give T2 site storage evolution talk 4/10/17 at gridpp-storage meeting

Tuesday 14 Nov

• Single processor LHCb stoppable Monte Carlo VMs running in a mixture with fixed length 8 processor ATLAS VMs and single processor GridPP VMs. Please get in touch if you are running Vac and want to try this.

Tuesday 3 Oct

• Productions tests of Vac 03.00pre at Manchester.

Tuesday 24th Oct

• A talk on end-to-end validation of any site's APEL accounting was presented at the WLCG Accountuing Taskforce meeting, 19th Oct. There slides exist here: https://indico.cern.ch/event/673843/contributions/2756986/attachments/1542818/2420233/blackBoxAccTesting.pdf

Monday 16th January

• The discussion topic for next week will be accounting comparisons. Please note Alessandra's comments last week.

Monday 14th November

• Alessandra has written an FAQ to extract numbers from ATLAS and APEL avoiding the SSB.

Monday 26th September

• A problem with the APEL Pub and Sync tests developed last Tuesday and was resolved on Wednesday. This had a temporary impact on the accounting portal.

• APEL status: An issue at Sheffield?

TEMPORARY NOTICE

VOMS servers located at CNAF have been knocked out due to some flooding. It is not known when they might be recorvered. Hence, at present, there are no VOMS servers at all for both planck or ipv6.hepix.org. And a single new VOMS server has been provided for enmr. See the VOMS records in the Approved VOs document for details.

• Safari on macOS autogenerated client certificates fix put into production last week.

Tuesday 19th Sept 2017

• Bug in Safari on macOS causes random Apple generated client cert to be presented to www.gridpp.ac.uk using a CA we don't know about. The connection is then rejected by Apache. Other browsers ok since we request but do not require that they supply a certificate. Workaround produced by (a) installing the Apple CA root and intermediary CA and (b) whitelisting UK e-Science DNs (+ CERN? Others?) in the HTTPS Wiki plugin. Tested but not yet in production.

Tuesday 4th July

• There were a number of useful links provided in the monitoring talks at the WLCG workshop in Manchester - especially those in the Wednesday sessions.

Monday 13th February

• This category is pretty much inactive. Are there any topics under "monitoring" that anyone wants reported at this ops meeting? If not we will remove this section from the regular updates area of the bulletin and just leave the main links.

Tuesday 1st December

• Sites are kindly invited to update the monitoring status page at https://www.gridpp.ac.uk/wiki/Site_monitoring_status

Tuesday 16th June
