The Apache SQL analyser allows SQL queries to search through Apache logfiles.
The installation of asql can be done via the package or source download, and once it's ready to use, users can start the shell by typing "asql". The shell features several commands that are available to users, including help for a complete list. The three most commonly used commands are: load, select, and show.
Load is used to load an Apache logfile into the temporary database created at startup. Single files or globs are accepted, so users can specify file paths like "load /var/log/apache2/acces*". To save time parsing input files more than once, the resulting database can be saved with the save command and restored later.
Select helps users run an actual query, while show displays the table structure the logfile was parsed into. A sample session provides a demonstration of typical usage of the shell, including the use of the alias command that allows creating persistent aliases.
Overall, Apache SQL analyser is a useful open-source software tool that can simplify and streamline the process of querying Apache logfiles.
