|This article needs additional citations for verification. (November 2011) (Learn how and when to remove this template message)|
General purpose, language independent
The following tools work based on log files that can be generated from various systems.
- TimeToPic visualizes a log file. If system has logging facility, its output can be shown on visual timeline. Developer can see from visualization what is happening on log. Can be used for code and "logic" level analysis. There are version for Windows and Linux. Supports log sizes up to 1 Gigabyte.
- time (Unix) - can be used to determine the run time of a program, separately counting user time vs. system time, and CPU time vs. clock time.
