20 Open UK Tickets this week.

Link to all the UK Tickets.
Whilst the number of tickets for the UK is low, a good few of the them are looking a bit neglected.

Atlas Pilots at RALPP
126632 (14/2) This is likely not a site problem, but I directed this atlas ticket RALPP's way to see if Chris can shed a little light onto what's up. Assigned (15/2)

Sno Space at Liverpool
126554 (10/2) After discussion last week Liverpool have rolled a Sno+ spacetoken. John is waiting on news from David to see how things work out, and if it all goes well the rest of us that support Sno+ will be asked to follow suit. In progress (20/2)

Atlas Monitoring Survey
126184 Yet another reminder that atlas are collecting feedback concerning site monitoring - feel free to add to the google doc yourself or forward your thoughts to atlas uk cloud support. In progress (7/2)

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

• 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.
