Presentation Transcript

  1. Background • OPS measure of reliability was instrumental in improving site reliability • And was “easily” understood • Became a metric shown to funding agencies as an indicator of MoU adherence • SAM & Nagios frameworks very useful in relaying monitors and alarms to sites • VO-specific monitoring started in SAM/Nagios and then was also implemented in dashboards • Reporting comes from the SAM/Nagios tests; but experiments rely on the dashboard tests

  2. What now? • OPS tests don’t represent what the experiment sees of a site • But we need to keep them for reporting; OR replace them with something more representative but still understandable • VO-tests: • Are the SAM/Nagios VO tests useful? • Should they be replaced by the dashboard tests (are they different?) • Still need to publish to SAM/Nagios to enable relaying to sites and to the report generation

  3. Some comments • Some sites see the utility of having OPS and VO tests (but SAM-VO tests could be replaced by the dashboard tests) • Tests may not always execute if a site is busy • esp. if run as normal user • Better to run as part of pilot? (solves “special” WN, queue issue too)
