Abstract: On an operational basis, several tests are executed to assess the performance and state of hardware of the LOFAR telescope. Usually, such tests are tailored to a specific purpose but, if combined, they can improve the assessment of the conditions of the telescope or give insight on their own robustness. Unfortunately, the results of such tests are stored in custom data formats and scattered throughout the system. Additionally, there generally is a lack of tools exist to present a nice view complicating the correlation and analysis of the data for the user. The station test and the RTSM (Real-Time Station Monitor) have been used during the years to gauge the conditions of the LOFAR stations' hardware. To this aim, we have built the StationMonitor. The StationMonitor consists of a database with middleware to ingest and provide access to the data through a REST API and a web user interface. Here, we will present the methodology used and the lessons learned.
