Monday 12th September 2016, 15.00 GMT
33 Open UK tickets. Down to 29 this morning!

I'm just going to skim the Sussex tickets, I'll contact Jeremy M about these again offline.
122772 (On Hold) - Atlas webdav/xroot ticket.
123230 (In progress) - Atlas transfer failures, was partially fixed as of 15/8.
123740 (Assigned) - Recent low availability ticket.
123733 (Assigned) - Ops SRM-LS test failures.
122614 (In progress) - Technically a ticket to the NGI concerning the Sussex status, not a Sussex ticket.

123859 (12/9)
CMS noticed that the Phedex agents appear to be down at RALPP. Fresh this afternoon. Assigned (12/9)

123858 (12/9)
A duplicate of above, I believe because you run 2 Phedex boxes? Assigned (12/9) Update - one of these was a duplicate, but they're both solved, network issues seemed to be the underlying problem.

123804 (9/9)
Low availability ticket, Chris provided an explanation and notes that there have been no tests since - possibly related to the problems noticed in this morning's EGI broadcast. In progress (9/9)

121924 (2/6)
A ticket from Duncan concerning a drop in perfsonar throughput rates at Oxford. Currently on hold - any ideas perhaps when you'll get round to looking at this? On hold (10/8)

123860 (12/9)
Another fresh "Phedex is down" ticket from CMS. Assigned (12/9) Update - solved alongside the RALPP tickets.

122771 (11/7)
Atlas ticket requesting xroot and webdav endpoints. The submitter requests an update. In progress (12/9)

120351 (22/3)
Enabling LSST at Glasgow. Any news, or plans for having any news soonish? On hold (19/7)

122378 (28/6)
No perfsonar results for Glasgow, the server appeared borked so David took it down. Is it soon due to rise from the ashes soonish? On hold (28/6)

123732 (5/9)
Nagios ticket for ce6 and ce7, which I believe are defunct CEs? Marcus has put the ticket on hold until Andy is back. On hold (5/9)

123164 (28/7)
Another nagios ticket, a glue2.validate one this time. Andy was confused about where this was coming from, and I assume the alarm is still happening. Perhaps the glue-validator will yield some clues? Waiting for reply (29/8)

122653 (7/7)
The third nagios ticket for ECDF, this one covers the odd saga of the ARCHER queue that would ideally be "IN PRODUCTION, NOT MONITORED". Waiting for reply (this probably should on hold instead) (5/9)

123810 (9/9)
LHCB noticed that the arc CEs were producing an incorrect number of running/waiting jobs (was this the catalyst for the tb-support thread on the same subject?). The ticket could do with acknowledgment, perhaps someone in the know could lend Durham a hand. Assigned (9/9) In progress now

123851 (12/9)
APEL-pub ROD ticket. Matt R has rerun the apel publishing scripts by hand and is awaiting the results, if this doesn't work we might need to ask the apel people how things are looking their end. In progress (12/9)

123813 (10/9)
Atlas deletion errors, probably due to a downed disk server that has been brought back up. In progress (12/9) Solved.

123789 (8/9)
LHCB jobs failing at Lancaster, probably because they're sensitive to some problems we had with our NFS server housing home and sandbox areas. We've hopefully soothed our problems by upping the number of nfs threads, we're in the wait and see period. In progress (12/9)

123734 (5/9)
ROD apel ticket for UCL. Ben is investigating, it looks like some VAC boxes are having trouble talking to the network. In progress (7/9)

123400 (15/8)
Low availability ticket for QM, but Daniela notes the alarms appear to have cleared so this should be able to be closed. On hold (12/9)

123451 (18/8)
LHCB had problems with a QM CE, which Dan noticed was fubared and needed a reinstall. Should hopefully be back online soon? On hold (18/8)

Raul solved the two tickets before I could get to them, nicely done.

100IT have a ticket - 123753 (6/9) but you don't have to bring yourselves to look at it.

The TIER 1
123794 (9/9)
Atlas noticed a lot of analysis job failures, after some prodding it turned out that the culprit was one dodgy worker node. Case closed? In progress (9/9)

122827 (12/7)
Sno+ asking for more disk, this has developed into some discussion and Alastair has added a few more points. Matt M has expanded on the Sno+ needs, and has decided to make more use of Tier 2 space for Sno+, which many or may not keep them ticking over until Echo is upon is. In progress (24/8)

120350 (22/3)
Enabling LSST at RAL. "Proper" test jobs are failed, Alessandra has put the ticket on hold until the issue can be debugged properly.

123504 (19/8)
Jon Perkins noticed that the WMSes at RAL didn't seem to be updating proxies at Sheffield for some long T2K jobs. A conversation was started but seemed to have stalled, it seemed some weird resource matching errors were going on. The landscape might have changed in the last 3 weeks however. In progress (23/8)

122364 (27/6)
cvmfs support for solidexperiment.org. After some solid progress the ticket is on hold waiting for someone VO side to try to roll out some experiment software in anger. On hold (24/8)

117683 (18/11/2015)
Developing glue2 support for Castor. Any update will do?! On hold (5/4)

119995 (7/3)
The culling of the uncertified sites. The old Glasgow Pre-production service was mentioned too. In progress (23/8)

So long EFDA-JET
122198 (17/6)
The jet decommissioning ticket. The other related ticket (123291) was closed as I wrote this report, so it won't be long until this ticket should be closed. Bye Jet! On Hold (1/9)

Tools - MyEGI Nagios

' 13th September 2016

19th July

Both instances of gridppnagios at Oxford and Lancaster has been decommissioned.

12th July 2016

Central ARGO monitoring service has started from 1st of July. All grid resources are monitored through two Nagios instances



It has same interface as gridppnagios. Alarms from these instances goes to Operational Dashboard

http://argo.egi.eu/ is a web interface which provides availability/reliability figures and site status. It is equivalent of old myegi interface with some additional services.

I am planning to decommission both instances of gridppnagios in coming weeks. I have stopped nagios and httpd on both instances so it will not send tests to grid resources in UK. I will also decommission storage-monit.physics.ox.ac.uk which was only used for storage replication test.

We will keep vo-nagios.physics.ox.ac.uk running until we get a replacement for vo-monitoring.

Monday 13th June

  • Active Nagios instance moved to Lancaster

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.
VOs - GridPP VOMS VO IDs Approved VO table

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.
Site Updates

Tuesday 23rd February

  • For January:

ALICE: All okay.

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

RALPP: 80%::80%

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.
