Site Sonar - A monitoring tool for ALICE’s Grid Sites

As the data collected by the LHC increases, the demand for computing resources follow. The JAliEn middleware was created to handle the high-throughput of data expected from ALICE in Run 3. However, making the sites in ALICE's Grid ready for the upgrade from the AliEn middleware to the JAliEn middleware is an laborious task. Therefore it was suggested that the JAliEn middleware could run in a containerized environment. The Site Sonar tool, designed using the Design Science Research methodology, will help the JAliEn developers discover what sites are not ready for the upgrade, and which can run a container with JAliEn. Site Sonar gives users the ability to retrieve information from sites, and has become a general tool which can be used for purposes beyond what it was first intended
