Statistics Gathering Once an day or once a hour, LogView compiles the desired statistics from the logs and updates its internal databases. These updates does not significantly slow down the server even on large sites where the logs can become equally large. LogView handles log files of gigabyte size without any performance problem, and it compresses its own log files to less than 1/4 of the size of an ordinary log file in the Common Log Format. LogView uses the term statistics group as a base for extracting statistic information from the logs. LogView can be configured to handle several different statistics groups, each one taking its data from an individually specified set of logs. Each group is also individually configured to use a number of functions to extract the corresponding kinds of statistics, such as file down-loads and the names of visiting hosts, from the group. The complete set of functions available in LogView at the time of writing of this manual is presented in appendix A. |
