Practical study is considered a backbone of qualification in engineering and sciences education. It aids understanding of the theoretical concepts for university students. Over the last decades, a limitation in available labs has become one of the encumbrances for several universities and institutions because of the cost and unavailability of instructors. It has led to decline in the students' qualifications in experimentation in engineering and sciences fields. Today, several ideas have implemented to get over the limitations of a lab, for example online labs technology, which are also referred to as, "Remote and Virtual Labs". This technology is become available over Internet, for instance Virtual Instrument Systems in Reality (VISIR). In addition, online labs prove that they can assist hands-on laboratories and may become the best technology for supporting hands-on one, regarding its low cost and ubiquity. This paper presents the number of students (access and users access) who are involved in using VISIR nodes that located at BTH, Deusto, ISEP, and UNED institutions. The filtration that used in this study is to categorize yearly and monthly access of students from those VISIR nodes.
