Logria is a terminal-based application for monitoring, filtering and aggregating log messages. Written in Rust, it provides an interactive environment for investigating the output of running processes and other sources of diagnostic information.
The application is particularly suited to situations where information arrives continuously and the criteria for investigation may change as problems become better understood. Users can refine their analysis while preserving the log messages already collected.
Logria works with shell commands as well as files, making it useful for monitoring services running on local computers or remote systems. Its combination of parsing and aggregation facilities helps turn streams of text into more meaningful information.
This is free and open source software.
Key Features
- Live monitoring – displays output from files, shell commands and running processes.
- Interactive filtering – applies regular-expression filters to incoming messages.
- Editable expressions – changes filters without restarting the monitored process or losing buffered history.
- Custom parsing – extracts information from log messages using user-defined rules.
- Live aggregation – calculates statistics from parsed messages as new information arrives.
- Saved sessions – preserves monitoring configurations for later use.
- Reusable parsers – stores custom parsing definitions for recurring log formats.
- Search highlighting – visually identifies messages matching search expressions.
- Output stream selection – switches between standard output and standard error.
- Buffer navigation – moves through retained messages independently of incoming output.
- Keyboard controls – provides commands for searching, filtering, parsing and aggregation.
