I needed a tool to view multiple log files in a merged view, and easily filter based on the specified fields. Spent a good amount of time searching, but couldn’t find any open source tool that quite did what I wanted. So, ended up building a custom solution instead (I would appreciate suggestions on tools that have similar functionality).
I don't know much about GUIs (most all my PC based utilities are CLI) - but I did have the following:
- I know enough Python to spot obviously wrong things
- Some knowledge of how to make programs performant in general
- ... and tokens to burn :)

Key Features:
- Merge and display multiple log files in a single, chronologically ordered view
- Live log monitoring with auto-scroll
- Add files individually or discover them recursively with regex filtering
- Plugin-based system to support any log format (easy to extend!)
- Filtering: discrete values, numeric ranges, regex/text, and time-based queries
- Color-coded file identification
- Configurable columns and ordering
- Built-in plugins for syslog, CANKing (CAN Bus monitoring tool), and another custom log format called dbglog.
