Xlogmaster

Based on standard UN*X commands that perform similar tasks, these modes are named as follows: **TAIL Mode**: Xlogmaster will read the file and then periodically (default: 0.3 seconds) check for any changes—essentially the same functionality as `tail -f`, but easier to handle and view. If you're monitoring more than two log files, things become much simpler. **CAT Mode**: This mode continuously "captures" the file/device you specify at user-defined intervals. The first thing you might think of now is: "Cool! I can track all the /proc devices I'm interested in." (Right? :-)) Anyway—I really like this mode. **RUN Mode**: Run Mode allows launching a program and retrieving its standard output. This enables you to write shell scripts/programs to gather any data important to you and monitor the output in Xlogmaster—with all the features Xlogmaster offers. The retrieved information can then be piped through plugins—plugins take the data from stdin and output it to stdout, which is read again by Xlogmaster. This allows you to translate cryptic log files or extract information in a special way. After reading data from TAIL/CAT/RUN modes (and piping it through plugins if needed), it can then be processed in certain ways. The most obvious one is displaying it in a text window. To make this more comfortable, you can define filters that allow you to highlight, suppress, or hide lines based on extended REGEX matches. Starting from version 1.3.0, Xlogmaster also supports background monitoring—you can define filters that trigger certain actions based on case-insensitive substring matches. The entry doesn’t need to be active for this. George introduced the classification of filters to help demonstrate how they work at different levels. Class0 filters are applied during display, while Class1 filters are used in the background. The implemented filters are:

Xlogmaster is a system monitoring program that helps users track log files, device outputs, and program outputs in TAIL, CAT, and RUN modes, with support for data processing and filtering.
