Weekly Summary of Support-Related Events and Alarm Tickets for WLCG Services

This report summarizes the support incidents related to WLCG services over the last 7 weeks, highlighting alarm tickets from ATLAS and CMS. Since the last management board meeting on June 7, a total of 11 real alarm tickets were submitted, with corresponding issues resolved. Notably, there was an email notification failure affecting CERN operators due to a change in the sender’s email. The report includes specific details on alarms related to CERN's SRM connections and storage issues, as well as recommendations for adjusting totals based on any alarms during July.

  2. Support-related events since last MB NB!!!!!!!!!!!!!!! CHECK IF THERE ARE MORE ALARMS BETWEEN 13-24 July & adjust totals below!!!!!!!!!!! There were 11 real ALARM tickets since the 2011/06/07 MB (7 weeks), 9 submitted by ATLAS, 2 by CMS, all ‘solved’, some even ‘verified’, 10 of them for CERN and 1 for CNAF. The 1st 5 ALARM tickets for CERN did not generate the required email notification to the CERN operators and experts on call! This was due to a switch of the sender’s email address from helpdesk@ggus.org to apache@ggus.org that happened with the 2011/05/25 GGUS Release due to the new exim mailer at KIT. This was solved in the week of 2011/06/27 by including this new email address in the CERN [VO]-operator-alarm@cern.ch e-groups’ admins. All test ALARMs following the 2011/07/06 release were successful. Details follow… WLCG MB Report WLCG Service Report
