22 Open UK Tickets this month.

SUSSEX
122772 (11/7)
atlas xroot/http ticket. No progress expected till January, but Jeremy M has noted this in the ticket. On hold (21/11)

124614 (24/10)
Availability ticket, on hold as is S.O.P., but this one is hanging around longer then usual. Perhaps it has something to do with the blips of "Unknown" status? On hold (14/11)

RALPP
125320 (2/12)
Intermittant nagios test failures for the RALPP dcache - Chris is fighting load issues but sadly doesn't seem to be reporting much luck. In progress (2/12)

OXFORD
121924 (2/6)
Perfsonar performance drop at Oxford. Pete G updated the ticket reporting a similar issue to that seen elsewhere - the perfsonar isn't filling up the available bandwidth. On hold (5/12)

BIRMINGHAM
122771 (11/7)
Atlas xrootd and http ticket - any luck (or lack thereof) with it Mark now that you're not dealing with ungrateful undergrads? In progress (29/11)

125169 (24/11)
Small VO acls on the Birmingham batch system, Mark is just getting round to look at this too. In progress (29/11)

GLASGOW
124821 (3/11)
One of the AFS tickets - on hold whilst Gordon asks around to see who's using afs. On hold (16/11)

124052 (25/9)
LHCB ticket about the incorrect job numbers reported by the Glasgow ARCs. IIRC the Glasgow position is to wait on an official release with the fix? No movement on the linked bugzilla or ticket. Booo. On hold (26/9)

EDINBURGH
124758 (1/11)
Another Availability ticket (which I'm thinking of renaming "Bauer-Banes" for how much they righteously annoy Daniela). Just waiting for it to clear. On hold (14/11)

125209 (27/11)
ECDF failing apel sync tests. Andy added their apel node (back?) into the gocdb, and things are looking better, although there is a gap in October. If this hole can be plugged then the ticket can be closed I think (if it can't then the ticket can also be closed, but it would be a less happy ending). In progress (1/12)

MANCHESTER, LIVERPOOL and RHUL AFS TICKETS
124822 (3/11)
The Manchester ticket was referred to Sabah (who in turn referred it to the Uni firewall admins)- Andrew M noted his righteous displeasure at the Tier 2s being ticketed about this. I would advise self closing the ticket (or at least on holding it). In progress (8/11)

124819 (3/11)
John B fielded this for Liverpool, again it's a ticket that could do with being On Holded if you don't want to just close it. In progress (3/11)

124816 (3/11)
Simon fielded the RHUL ticket, forwarding the information on. Same deal as the previous two tickets with this chap. In progress (7/11)

THE TIER ONE
124606 (24/10)
CMS consistency checking ticket - Andrew L is deletions in progress so this is chugging along nicely now. In progress (2/12)

124876 (7/11)
Nagios test failures to the echo instance - Alastair has been working on getting the probe fixed so it's relevant to this object store (see 125026). On hold (21/11)

125348 (5/12)
Request from CMS to update phedex- Andrew L has added it to this week's to do list. In progress (5/12)

125325 (3/12)
Atlas MCORE job stagein failing - possibly due to problems with some disk servers/switches that occured overnight, although Brian points out that FTS transfers are okay. Looking on panda though I don't think the picture has improved greatly. In progress (5/12)

125157 (24/11)
Creation of a cvmfs repo for extras-fp7.eu. Catalin has worked hard debugging some user problems, just skimming the ticket but things are looking better for the user now (after switching UIs!), they should be uploading stuff soon. In progress (2/12)

124478 (17/10)
na62 WMS jobs getting stuck forever at RAL. Dan from na62 has asked for an update. In progress (29/11)

122827 (12/7)
Sno+ ticket asking for more disk space. Gareth asked for an update, and David reports that there hasn't been any recent complaints about MC access times. Perhaps the ticket can be closed? In progress (1/12)

117683 (18/11/2015)
Castor not publishing glue2 - Jens updated in October with word that available effort for developing this is minimal, this should tide the ticket over till next year. On hold (5/10)

JET-TING OFF 122198 (17/6)
I forgot to talk to Jeremy about closing Jet in the GOCDB last week, I'll do it this week. In progress (5/12)

29th November 2016

LSST monitoring is available through vo-nagios

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

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

https://argo-mon.egi.eu/nagios/

https://argo-mon2.egi.eu/nagios/

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.

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.
