Mandate

  • assess the support status of various Nagios probes available
    • recommend removal or replacement of unsupported probes from the SAM Nagios framework
  • improve documentation:
    • availability of references to the individual nagios probes/tests descriptions in a central place
    • update known documentations web pages with proper references (avoid broken links)
    • improve developers guides
    • require change to SAM to remove harcoded documentation URLs in metrics configuration

Tasks

Documentation

Generic improvements

  • eliminate Broken Links
  • collect all documentation links in a central place
  • create a unique page collecting descriptions of all available tests/probes

Developers Documentation

  • collect requierments and suggestions from Developers

Probes

Identified Issues

  • NGI SAM Nagioses have documentation URL hardcoded in metric configuration
    • changing the URLs requires SAM update
    • Solution: - Plan the Change
  • SAM CE Nagios framework is unsupported
    • used for WN* tests
    • Solution: - replace them
  • SRM tests (add reference) cause false alarms on new DPM versions (add link to GGUS tkt)
    • Solution: - ??
  • org.gstat.SanityCheck - not maintained anymore
    • checks small subset of BDII GLUE 1.2 data
    • (add reference to profiles were it is enabled)
    • Solution: replace with org.bdii.GLUE2-Validate - through validation of GLUE 2 data
  • LFC decommissioning - with implications in tests depending on it
    • org.sam.WN-Rep* (CREAM-CE)
    • org.sam.WN-Rep* (CREAM-CE)
    • Solutions:
      • remove all LFC-dependent tests, or find replacement
      • deploy dedicated LFC and reconfigure all NGI SAM Nagioses
  • SAM requires unsupported software
    • UMD 2 middleware:
      • Solution: migration to UMD-3 planned in September - FOllow-Up
    • CentOS/SL5
      • Solution: - migration to CentOS/SL6 planned within EGI InSPIRE JRA2 activity
  • org.sam.SRM-GetTURLs fails if webdav is published
    • the probe takes from the BDII the list of protocols published in the GlueSEAccessProtocol object and tries to access them using SRM. This fails for webdav.
    • Solution:
      • CERN DPM PT is developping a webdav SAM probe
      • improve org.sam.SRM-GetTURLs, under dCache PT maintenance, to not ask/test SRM for a webdav TURL
