Tuesday 8th December

• Given the recent network issues and role of GridPP DIRAC, there are plans to have a slave DNS for gridpp.ac.uk at Imperial and hopefully the T1 too. Andrew will seek an update to the whois records and name servers once the other host sites are confirmed.
• Looking at the network problems this week will be of interest. Duncan supplied this link and Ewan the one for the dual stack instance.

Tuesday 5th April 2016

Oxford had a scheduled network warning so active nagios instance was moved from Oxford to Lancaster. I am not planning to move it back to Oxford for the time being.

Tuesday 26th Jan 2016

One of the message broker was in downtime for almost three days. Nagios probes picks up a random message broker and failover is not working so a lot of ops jobs hanged for long time. Its a known issue and unlikely to be fixed as SAM Nagios is in its last leg. Monitoring is moving to ARGO and many things are not clear at the moment.

Monday 30th November

• The SAM/ARGO team has created a document describing Availability reliability calculation in ARGO tool.

Tuesday 6 Oct 2015

Moved Gridppnagios instance back to Oxford from Lancaster. It was kind of double whammy as both sites went down together. Fortunately Oxford site was partially working so we managed to start SAM Nagios at Oxford. Sam tests were unavailable for few hours but no affect on egi availibilty/reliability. Sites can have a look at https://mon.egi.eu/myegi/ss/ for a/r status.

Tuesday 29 Sep 2015

Following an air-conditioning problem at machine room in Oxford Tier-2 site on 26 September, gridppnagios(OX) was shut down and gridppnagios(Lancs) became active instance. Oxford site is in downtime until 1st Oct and it may be extended depending on the situation. VO-Nagios was also unavailable for two days but we have started it yesterday as it is running on a VM. VO-nagios is using oxford SE for replication test so it is failing those tests. I am looking to change to some other SE.

Tuesday 19th May

• There is a current priority for enabling/supporting our joining communities.

Tuesday 5th May

• We have a number of VOs to be removed. Dedicated follow-up meeting proposed.

Tuesday 28th April

• For SNOPLUS.SNOLAB.CA, the port numbers for voms02.gridpp.ac.uk and voms03.gridpp.ac.uk have both been updated from 15003 to 15503.

Tuesday 31st March

• LIGO are in need of additional support for debugging some tests.
• LSST now enabled on 3 sites. No 'own' CVMFS yet.

• Impact
  • Citation policy (https://www.gridpp.ac.uk/acknowledging.html)

Tuesday 23rd February

• For January:

ALICE: All okay.

• ATLAS:

RHUL 89%:89% Lancaster 0%:0%

• CMS:

RALPP: 80%::80%

• LHCb:

RALPP: 77%:77%

• Site responses:

• • RHUL: The largest problem was related to the SRM. The DPM version was upgraded and it took several weeks to get it working again (13 Jan onwards). Several short-lived occurrences of running out of space on the SRM for non-ATLAS VOs. For around 3 days (15-17 Jan) the site suffered from a DNS configuration error by their site network manager which removed their SRM from the DNS, causing external connections such as tests and transfers to fail. For one day (25 Jan) the site network was down for upgrade to the 10Gb link to JANET. Some unexpected problems occurred extending the interruption from an hour to a day. The link has been successfully commissioned.

• • Lancaster: The ASAP metric for Lancaster for January is 97.5 %. There is a particular problem with ATLAS SAM tests which doesn’t affect the site activity in production and analysis and this relates to the path name being too long. A re-calculation has been performed.

• • RALPP: Both CMS and LHCb low figures are due to specific CMS jobs overloading the site SRM head node. The jobs should have stopped now.
