Guardo Log Visualizer

Guardo is a VS Code extension to visualize structured log files with advanced filtering, search, and trace plotting capabilities.

Features

• Log Table Visualizer: View logs in a searchable, filterable table with node and level filters.
• Log Trace View: Visualize log events as a time-vs-node trace plot. Each node is a row, and log events are shown as colored arrows by severity. Hover for a compact tooltip with timestamp, node, and message.
• Performance Optimized: Handles large log files efficiently with WebGL rendering, compact tooltips, and X-only zoom.
• Explorer Context Menu: Right-click any .csv log file to open either the table or trace view directly.

Usage

1. Open a log file (e.g., log.csv or log_asm.csv) in VS Code.
2. Use the Command Palette (Ctrl+Shift+P):
   • Open Log Visualizer for the table view.
   • Open Log Trace View for the time-vs-node trace plot.
3. Or, right-click a .csv file in the Explorer and choose the desired view.

Log Format

• Header line (comma-separated), data lines (backtick- or comma-separated):

  stamp,level,name,msg,file,function,line
  1712592543310108072`30`Elastic Follow Planner`[ElasticFollowPlanner] ...
  

• The extension auto-detects delimiters and columns.
