timeplotters
Timeplotters are command-line tools for visualizing temporal data, especially useful for visualizing data from ad-hoc program logs to help you spot patterns and anomalies that you would not spot otherwise (by just watching how the program works, or by looking at the logs with the naked eye). They have been specifically designed for working with program logs: the input format is tailored to event types typically seen in program logs and the visualization methods are tailored to the questions typically asked about program performance (e.g. distribution of activity durations).
