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

• F Melaccio & D Crooks decided to add a FAQs section devoted to common monitoring issues under the monitoring page.
• Feedback welcome.

Tuesday 3rd October

• A new ROD rota poll needs to be circulated in the coming days.

6th June

• There are issues with the ARC CE tests again, so the ARC sites have not have any results in days and the corresponding availability tickets are going nowhere.
• New rota being compiled.

Tuesday 2nd May

• Generally quiet. A few low availability tickets.

Monday 13th February

• Please can we hear something from Raul and Sam (or others contributing to the middleware readiness work) about news in this area at the ops meeting next week? Thank you.
• Does anyone want specific questions in this area tackled in a roundtable discussion?

Tuesday 7th December

• Raul reports: validation of site BDII on Centos 7 done.

Tuesday 15th September

• UMD 3.13.3 is available.

Tuesday 12th May

• MW Readiness WG meeting Wed May 6th at 4pm. Attended by Raul, Matt, Sam and Jeremy.

• Staged Rollout pages (now separated into EMI1 & 2), and the page listing the deployed versions is extractable from the bdii, so they should all be reasonably up-to-date:

• Upcoming meetings
  • This afternoon at 3pm, Traceability and Isolation working group meeting: https://indico.cern.ch/event/667685/
  • October 11th, Authz: https://indico.cern.ch/event/670330/
  • November 7th: Authz pre-GDB
  • December 11th/12th: SOC WG Workshop/pre-GDB (details to be confirmed)

Monday 31st July

• Ian has now left GridPP. Please direct queries to the security team via ukngi-security at cern.ch.

- This includes notifying of (inter)national services that will have an outage in the coming weeks or will be impacted by work elsewhere. (Cross-check the Tier-1 update).

Tuesday 4th July

• Pete C is preparing another networking forward look document. Note that figures presented in the Manchester workshop were for a Tier-2 (not always a single site).

Tuesday 6th June

• An update from the DIRAC workshop? GridPP is still the only true multi-VO instance, so we will continue to see issues with this. release quality of dirac has improved within the past year. gfal2/EL7 problems seem to be coming to an end after being cooped up with all authors for 3 days on end. The Imperial GridPP module now has integrated testing. It was also noted that every dirac instance has it's own special module to adapt to their community on top of main dira. We are trying to push as much of out special functionality back into the main dirac branch.

Tuesday 25th April

• perfSONAR version 4 was released on 17th April. Sites with auto-update on should have been automatically upgraded. Note perfSONAR 4.0 requires more CPU than previous versions as a result of some of the increased functionality. Full details here

• Duncan has recreated the UK perfSONAR mesh. Link here!

Tuesday 18th July

• Following our ops discussion last week, Steve will focus his tests on supporting the GridPP DIRAC area and decommission the other tests.

https://vo-nagios.physics.ox.ac.uk/nagios/cgi-bin/status.cgi?servicegroup=lsst&style=detail

13th September 2016

• New wiki page has been created for ARGO Nagios https://www.gridpp.ac.uk/wiki/ARGO_Nagios_Monitoring. I will add some more information to it later.
• Removed old wiki links about sam nagios from gridpp wiki page.
• VO nagios still exist and working. I have opened a ticket to explore ARGO VO Nagios, https://ggus.eu/index.php?mode=ticket_info&ticket_id=123604
