DIRAC SAM

These tests stopped running in 2020, hence this page is obsolete. For anyone interested, the GridPP DIRAC server is monitored by nagios jobs that are submitted on behalf of (most of) the supported VOs on a regular basis.

The GridPP DIRAC SAM tests are run several times a day to verify that sites are able to run DIRAC payload jobs from the GridPP DIRAC service.

The system is very simple:

• jobs are submitted to a list of DIRAC sites from a cron job on lxplus at CERN every 6 hours
• a script on the GridPP web server is contacted to record that a SAM job has been submitted
• hopefully the payload job is retrieved by the JobAgent on a worker node or VM and run
• the job contacts the web server script to record that the job has run successfully
• jobs which remain in the DIRAC Waiting state for more than 48 hours are deleted

The results of SAM jobs are visible on the GridPP web server: http://www.gridpp.ac.uk/php/gridpp-dirac-sam.php?action=view
