The LHCb experiment has chosen to use the SAM framework (Service Availability Monitoring Environment) provided by the WLCG developers to make extensive tests of the LHCb environment at all the accessible grid resources. The availability and the proper definition of the local Computing and Storage Elements, user interfaces as well as the WLCG software environment are checked. The same framework is also used to pre-install the LHCb applications in the shared software area provided by each site. The deployment of the LHCb applications is based on a python tool developed inside the experiment. It is used for software management including incremental installation of interdependent packages and clean package removal. The software installation is followed by a full application run tests. According to the results of the experiment specific SAM tests, the sites are allowed to be used in the LHCb production system called DIRAC. The possibility of automated dynamic site certification using the SAM test suite is explored. This paper will describe the various ways of the LHCb use of the SAM framework. Practical experience in the recent production runs, current limitations and future developments will be presented.
