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.

- 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!

27 Open UK Tickets this week.

BIOMED PUBLISHING QUERIES
https://ggus.eu/?mode=ticket_info&ticket_id=130264 (RALPP's ARC CE)
https://ggus.eu/?mode=ticket_info&ticket_id=130263 (BRUNEL's ARC CE)
https://ggus.eu/?mode=ticket_info&ticket_id=130262 (QMUL's STORM SE)
Biomed have thrown a bunch of tickets our way, along the theme of "publishing invalid data". Interestingly the ARC devs have stepped in to the Brunel ticket.

OXFORD
https://ggus.eu/?mode=ticket_info&ticket_id=130032 (11/8)
LHCB having trouble uploading job outputs. Similar to other issues seen, there are some tests in the linked ticket (130190) that Raja would like to try out. If there is still a problem it would be worth trying out those tests. Also the last update mentions some odd behaviour at QMUL between July and August, which righted itself but may provide a clue. In progress (23/8)

Two other OXFORD tickets could do with an update (even if there's no progress):
https://ggus.eu/?mode=ticket_info&ticket_id=129931
https://ggus.eu/?mode=ticket_info&ticket_id=130173

BIRMINGHAM
https://ggus.eu/?mode=ticket_info&ticket_id=130274 (28/8)
Birmingham "underperforming" for na62, mainly as they might not be submitting to the VAC resources. Are na62 jobs automagically sent to a site's VACs? In Progress (31/8)

BRISTOL
https://ggus.eu/?mode=ticket_info&ticket_id=130386 (5/9)
xroot not working for the GridPP VO at Bristol. Winnie posted an interesting question - does xroot require any v6 specific configuration, as some behaviour in the logs suggests that it might. In progress (7/9)

QMUL
https://ggus.eu/?mode=ticket_info&ticket_id=130232 (25/8)
A quick note that this icecube GPU issue looks solved, so this ticket can be closed. In Progress (26/8)

https://ggus.eu/?mode=ticket_info&ticket_id=130574 (14/9)
An LHCB ticket about "not enough jobs running at QM", although it's more a lesson in fairshare and expectation management, as Daniel points out LHCB has had a lot of CPU over the last few months. I think the ticket should be "Waiting for Reply" though. In progress (15/9)

TIER 1
https://ggus.eu/?mode=ticket_info&ticket_id=130193 (23/8)
CMS having trouble staging from tape at RAL, Brian points out that there seem to be a few missing files. Any news on this? Daniela points out that transfers have stalled for 3 weeks now. In progress (4/9)

https://ggus.eu/?mode=ticket_info&ticket_id=130467 (10/9)
Somewhat related, CMS SAM tests failing due to there being no room on CASTOR. Chris points out there seems to be 190TB unaccounted for. Waiting for reply (11/9)

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.

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
