Tuesday 31st January
A reminder that there is a weekly Tier-1 experiment liaison meeting. Notes from the last meeting here
- There were some problems following the Castor 2.1.15 update of the LHCb instance on the 18th. These problems were resolved by early evening the next day (19th). The Atlas instance upgrade took place successfully on the 24th. The GEN instance (ALICE plus non-LHC VOs) update is scheduled for the 26th and finally CMS on the 31st.
- We are still seeing a lot of CMS SRM test failures - which are attributed to load on the CMS Castor instance.
- We now have load balancers in front of our Top-BDIIs as well as the Site-BDIIs.

Monday 16th January
- Rota to be updated this week. Gordon is on shift this week.
Monday 9th January
- Daniela posted on 25th Dec to say: "there's quite a lot of tickets - I tried to extend them all into January.
Otherwise apparently the grid is still standing."
Monday 5th December
- Another fairly quiet week. There were a few new tickets, which are mostly now resolved. There was an intermittent SRM alarm at RALPP which sporadically appeared then disappeared; it finally hung around long enough today to raise a ticket.

- 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 25th October
- Duncan has recreated the UK perfSONAR mesh. Link here!
Monday 19th September
- UK eScience CA - certificate issuance problems. Jens reported that on 15th a partial but significant database corruption occurred on the signing system for the CA. Data was restored from (offline) backups but the rebuild was not correctly configured.
- A large number of site admins and other GridPP supporters appeared to be suspended from the dteam VO last week. “During a planned upgrade operation of VOMS service, a system malfunction occurred. As a result, some users received false notification about membership expiration. We are in contact with the software development team in order to identify the cause.”

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
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.

- 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
ALICE:
All okay.
RHUL 89%:89%
Lancaster 0%:0%
RALPP: 80%::80%
RALPP: 77%:77%
- 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.
