Page description:

  • Last update (timestamp)
    • If the page was not updated for 1 hour, it will turn red.
  • Site name
    • hovering over the site name provides a tooltip with links to MRTG monitoring pages of site's squids
  • history
    • link history of states in form of csv file (for easier searching)
  • f/r (fetch/request ratio)
    • Values of fetch and requests are taken from weekly average in 30 min bins of the MRTG.
    • The value is either f/r value of a single squid or, if there are more squids at the site, it is maximum of f/r values.
    • If there is less than 500 request on average, the ratio is set to 0 to avoid false alarms caused by inactive squids
    • Background color can change depending on the f/r value:
      • f/r>0.75
      • 0.75=>f/r>0.5
      • 0.5=>f/r>0.25
      • 0.25=>f/r
    • If the f/r value is "high", it means the squid has problem with caching and many requests are read from database instead of squid's cache.
  • Availability overview
    • Shows colored field representing availability of sites squid(s)
      • in case all site squids are OK
      • in case all site squids are down
      • in case there are some OK squids and some down squids
  • Failover information enrichment
    • if there was a failover from a site on any CVMFS stratum 1, it will be displayed as white F in Avalability overview
    • hovering over the F will show a plot with information about number of hits from the site
    • for sites which share their geoip, F will be displayed for each of them
