The SAM status codes with a brief description for the results of our tests are as follows:

  • OK 10 – Site has passed all tests
  • Info 20 – Not used
  • Notice 30 – Not all tests ran, see below
  • Warning 40 – Site queue length requirement is not satisfied
  • Error 50 – There was a problem during execution of the tests
  • Critical 60 – Critical problem found during execution
  • Maintenance 100 – Eventually will be set by a SAM agent

The current list of tests we perform start with a check on the presence of a ‘lock file’ in the shared area. This allows SAM tests to run at multiple CEs with only one being able to write into the shared area. If an existing SAM lock file is detected the software installation test is disabled and the lock test is set to ‘Notice’.

SAM Test Name Description Log File
CE-lhcb-lock Places a lock on the shared area sam-lock.log
CE-lhcb-os Performs checks on the local system sam-os.log
CE-lhcb-queues Checks the site batch queues sam-queues.log
CE-lhcb-install Installs the LHCb software sam-install.log
CE-lhcb-job- Runs the e.g. Gauss, Boole,… sam-job--.log

A summary of the installed software at the site is given in the SAM test results page and in case of errors, direct links to the log files and LogSE directory are provided.
