Web-hosting is a well established industry with a wide range of actors with different size and quality of service. One of the challenges for these companies is to setup a system that guarantee uptime around the clock. Web-hosts must be able to assure high reliability to its customer, in order to provide better services than the many competitors that exist on the market. This requires a lot of resources from the companies in form of hardware, software or personnel that monitor the operation 24 hours per day each day of the week. A problem is that small and medium sized companies with up to approximately 10000 customers can’t afford these extra costs for personnel and must therefore rely on other monitoring solutions to be competitive. This thesis will show how automatic monitoring tools can replace some of the responsibilities, performed by human personnel. The tools will also be evaluated and compared with similar tools available on the market. An economic model, that can be used to determine if the solution is worth investing in , is also described.
