The Tile Calorimeter (TileCal) is a crucial part of the ATLAS detector, which jointly with other calorimeters reconstructs hadrons, jets, tau-particles, missing transverse energy and assists in muon identification. It consists of alternating steel absorber layers and active scintillating tiles and covers the region |η| < 1.7. The TileCal is regularly monitored by several systems, which were developed mainly during the commissioning of the detector in order to meet distinct requirements. Any problem is reported and immediately investigated, which results in data quality efficiency very close to 100%, as achieved over the last few years. Although the TileCal tools are maintained, the underlying technologies are becoming gradually outdated.
The Tile-in-One web platform strives to integrate all data quality and condition assessment TileCal tools into one common system. This system is implemented as a web application with the main machine being the gateway for so-called plugins. These are standalone small web application hosted on a single virtual machine. The plugins are separated into virtual machines due to the requirement of different data sources and to avoid interference in order to increase the stability of the platform. The main server is responsible for the authentication and authorization of the users, as well as the management of the plugins. Currently the platform consists of 13 plugins in various stages of development. The implementation details of the Tile-in-One web system and selected plugins are presented in this document.
