Hi. I wrote up a simple little log file analysis program.
It is intended to produce runtime statistics for queries from a database, but it should be able to handle almost anykind of logfile as long as the log files contains lines with statements and the time it took to run the statement. These are extracted with regexp.

The goals is to produce graphs/etc to show the time it takes to run statements, to spot trends in running time and the number of times a statement is beeing run.
