Recomputations

The guide for recomputations is available at https://twiki.cern.ch/twiki/bin/view/ArdaGrid/ProfileCorrections

If there is a need for a central recomputation (i.e. done by us, instead of the experiments), the easiest way to do it is to login to wlcg-sam.cern.ch, and use the command /opt/dashboard/bin/SAM3Corrections.

[psaiz@wlcg-sam $ /opt/dashboard/bin/SAM3Corrections --help
Applying corrections to the SAM3 Availabilities
Usage: SAM3Corrections [options]

Options:
  -h, --help            show this help message and exit
  -p PROFILE, --profile=PROFILE
                        profile to overwrite
  -f START, --from=START
                        Start time and date (e.g. 2015-01-22 14:00:00)
  -t END, --to=END      End time and date (e.g. 2015-01-22 14:00:00)
  -v VALUE, --value=VALUE
                        Value to put (default=UNKNOWN)
  -o OLD_VALUE, --old_value=OLD_VALUE
                        Value to overwrite (default=CRITICAL, can be set to
                        all)
  -s SITE, --site=SITE  Sites to change (default 'all sites')

Once the recomputation has been done, and the new values appear on the web interface, the reports have to be generated again, with the command:

[root@wlcg-sam $  /opt/dashboard/cron/SAM3Reports.sh -m it-dep-cm-mm-rota@cern.ch

This command will send an email, to the Rota email, when the reports are available. The Rota should then send the final announcement as explained above.
