Abstract: A method and apparatus is disclosed where a web server (10) has its performance measured by performance data being sent, via the Internet or by similar means, to an analyzer (12) with a relational database management system (14) and a data storage database (16). The analyzer (12) analyses the performance of the web server (10) per se, and/or with reference to previous instances of analysis, and/or with reference to the results of analysis of performance data from other, similar computer systems, and/or with reference to manufacturers, vendors or suppliers data. The analyzer can generate one or other, or both of a humanly readable report, in the form of problems and solutions, and an instruction set of instructions to provide the solutions. The report is sent back to the web server (10) site to be acted upon by an end user. 'the instruction set can also be sent back to the web server (10), for the web server automatically to apply the solutions or under approval from the end user.
