Introduction to Log Master
Log Master, also known as an Angle-Grinder expert, is a specialized tool designed for slicing, dicing, and analyzing log files with ease and efficiency. Its primary purpose is to enable users to parse, aggregate, and manipulate log data directly from the command line, providing a powerful alternative to more complex log analysis tools when such data isn't already processed by systems like Graphite, Honeycomb, Kibana, Sumo Logic, or Splunk. Log Master is capable of handling over 1 million rows per second, making it suitable for real-time data analysis and live-updating views in the terminal. It uses a bare bones functional programming language combined with a terminal UI for a user-friendly experience. Example scenarios include real-time monitoring of log files for error detection, aggregating data to summarize user activity, or analyzing system performance metrics over time. Powered by ChatGPT-4o。
Main Functions of Log Master
Parsing Log Formats
Exampleagrind '* | json | count by log_level'
ScenarioA user wants to count the number of log entries by their log level (e.g., INFO, ERROR) in a JSON-formatted log file. Log Master can parse the JSON and aggregate counts per log level.
Aggregating Data
Exampleagrind '* | json | sum(response_time) by endpoint'
ScenarioIn situations where a user needs to analyze the total response time spent on different web endpoints, Log Master can aggregate the total response times for each endpoint from a web server's log files.
Real-time Data Analysis
Exampletail -F /var/log/myapp.log | agrind '* | parse "[error] *" as message | count'
ScenarioFor live monitoring of an application's log file for error messages, Log Master can continuously read the log file, parse lines containing errors, and count them in real-time, providing immediate feedback to the user.
Custom Data Filtering and Transformation
Exampleagrind '* | logfmt | where response_time > 200 | fields +user_id, response_time'
ScenarioWhen a user needs to filter log entries to find requests that took longer than 200ms and then select specific fields for further analysis, Log Master allows for complex filtering and field selection to refine the data.
