  • For Control Systems at Cern
    Evaluation of standard monitoring tools(including log analysis) for control systems at Cern August 2013 Author: Vlad Vintila Supervisor(s): Fernando Varela Rodriguez CERN openlab Summer Student Report 2013 CERN openlab Summer Student Report 2013 Project Specification The goal of this Openlab Summer Student project was to assess the implications and the benefits of integrating two standard IT tools, namely Icinga and Splunkstorm with the existing production setup for monitoring and management of control systems at CERN. Icinga – an open source monitoring software based on Nagios would need to be integrated with an in-house developed WinCC OA application called MOON, that is currently used for monitoring and managing all the components that make up the control systems. Splunkstorm – a data analysis and log management online application would be used stand alone, so it didn’t need integration with other software, only understanding of features and installation procedure. Abstract The aim of this document is to provide insights into installation procedures, key features and functionality and projected implementation effort of Icinga and Splunkstorm IT tools. Focus will be on presenting the most feasible implementation paths that surfaced once both software were well understood.

  • Analysis and Evaluation of Network Management Solutions a Comparison of Network Management Solutions Suitable for Networks with 2,500+ Devices
    DEGREE PROJECT IN COMPUTER ENGINEERING, FIRST CYCLE STOCKHOLM, SWEDEN 2016 Analysis and Evaluation of Network Management Solutions A Comparison of Network Management Solutions Suitable for Networks with 2,500+ Devices MURAT GABDURAHMANOV and SIMON TRYGG KTH ROYAL INSTITUTE OF TECHNOLOGY INFORMATION AND COMMUNICATION TECHNOLOGY Analysis and Evaluation of Network Management Solutions A Comparison of Network Management Solutions Suitable for Networks with 2,500+ Devices Murat Gabdurahmanov and Simon Trygg 2016-06-16 Bachelor of Science Thesis Examiner Gerald Q. Maguire Jr. Academic adviser Anders Västberg KTH Royal Institute of Technology School of Information and Communication Technology (ICT) Department of Communication Systems SE-100 44 Stockholm, Sweden c Murat Gabdurahmanov and Simon Trygg, 16 June 2016 Abstract Some companies today are using sub-optimal and nearly obsolete management systems for their networks. Given the large number of different services that are demanded by users, there is a need to adapt the network structure to support the current and potential future demands. As a result, there is a need for new Network Management Solutions (NMSs). The aim of this thesis project is to help a company who uses a NMS called Local Area Network (LAN) Management Solution (LMS). LMS was designed by Cisco for managing LAN networks. However, the company’s demands are growing and they need to expand their network more than expected. Moreover, LMS is designed to only support devices by Cisco, whereas the company wants a universal solution with wide device support from many manufacturers. This thesis presents an analysis of their current system and suggests potential solutions for an upgrade that will meet all of the company’s demands and will have a long operating life.
