About:
Angle-grinder is a command-line tool for analyzing structured log data in real-time. It allows users to parse, filter, and transform logs using a simple query language without needing complex regex. The tool's main value is providing immediate insights from log streams during live troubleshooting sessions.
Key Features:
  • Simple query language for log parsing
  • Real-time stream processing capabilities
  • Multiple output formats including tables and JSON
  • Pipeline-based filtering and transformation
Use Cases:
  • Live monitoring and analysis of application logs
  • Quick debugging of services by filtering log output
  • Parsing structured log files for specific error patterns
Alternatives:
  • jq – jq is more powerful for JSON manipulation but has a steeper learning curve
  • grep/awk – Standard Unix tools require complex regex for structured log parsing
