Description

The workshop, second one after the successful workshop at CERN in December 2014, is an opportunity for novice and experienced users of HTCondor to learn, get help and have exchanges between them and with the HTCondor and ARC developers and experts. It is primarily addressed at users from EMEA. The workshop will consist of presentations, tutorials and "office hours" for consultancy. The HTCondor CE (Compute Element) as well as the ARC CE will be covered as well. ALBA Synchrotron Light facility located in Cerdanyola del Vallès (Barcelona) act as the event host, with the additional help of Port d'Informació Científica (PIC) for event preparation/coordination. There is a fee of 80€ (VAT included) which covers the lunches and all coffee breaks along the event.

        Best Practices - Monitoring 30m
        Speaker: Todd Tannenbaum (Univ of Wisconsin-Madison, Wisconsin, USA)
      • 4:30 PM
        Effective HTCondor-based monitoring system 30m
        The CMS experiment at LHC relies on HTCondor and glideinWMS as its primary batch and pilot-based grid provisioning systems. Given the scale of the global queue in CMS, operators found it increasingly difficult to monitor the pool to find issues and fix them. Operators had to rely on several different webpages, with several different levels of information and sifting tirelessly through logs in order to monitor the pool completely. Therefore, coming up with a suitable monitoring system was one of the crucial items before the beginning of Run 2 to ensure early detection of issues and to give a good overview of the whole pool. Our new monitoring page (cms-gwmsmon.cern.ch) utilizes the condor classAd mechanism to provide a complete picture of the whole submission infrastructure in CMS. Monitoring page includes useful information from HTCondor schedulers, central manager, glideinWMS frontend and factory. It also incorporates information about users and tasks making it easy for operators to provide support and debug issues.
