⚡ How It Works

Start Analysis

You can analyze logs in two ways:

1. Analyze an Open Log File

• Open a .log file in VS Code.
• Run Log: Show Apex Log Analysis via:
  • Command Palette (Ctrl/Cmd + Shift + P)
  • Top-of-file code lens
  • Right-click menu
  • Editor toolbar button

2. Download a Log from Your Org

Use Log: Retrieve Apex Log And Show Analysis from the Command Palette.

⚙️ Recommended Debug Log Levels

• Set APEX_CODE level to FINE or higher — lower levels may omit important execution details.
• Be aware that higher debug levels introduce logging overhead, which can inflate recorded execution times.
• Avoid truncated logs — they can result in incomplete or misleading analysis.
• Recommended settings for a good balance of detail and performance: APEX_CODE,FINE; APEX_PROFILING,FINE; CALLOUT,INFO; DB,FINEST; NBA,INFO; SYSTEM,DEBUG; VALIDATION,INFO; VISUALFORCE,FINE; WAVE,INFO; WORKFLOW,FINE

🔥 Flame Chart Timeline

The Flame Chart view shows a timeline of the Salesforce Apex log execution — including methods, SOQL queries, DML operations, workflows, flows, and more.

• Zoom & Pan – Navigate your logs down to 0.001 ms with precision zoom.
• Tooltips – Hover for duration, event name, SOQL/DML/Exception counts, SOQL/DML rows, and more.
• Click to Navigate – Click any event to instantly view it in the interactive Call Tree.
• Stacked by Time – See how execution time is distributed across nested method calls and system events.

🧠 Great for spotting long-running operations, inefficient queries, and bottlenecks.

🌲 Call Tree

Explore nested method calls with performance metrics:

• Metrics: Self Time, Total Time, SOQL/DML/Thrown Counts, SOQL/DML/Rows
• Filter by Namespace, Type or Duration
• Toggle Debug-Only + Detail Events
• Keyboard Navigation
• Click to go to Code – Jump to the source method in your project

🧠 Apex Analysis

See which methods are the slowest, most frequent. or expensive.

• Group by Type or Namespace
• Sort by Duration, Count, Name, Type or Namespace
• Filter to specific event types
• Copy or Export to CSV

🗄️ Database Analysis

Highlight slow Salesforce SOQL queries, non-selective filters, and DML issues.

• SOQL + DML Duration, Selectivity, Aggregates, Row Count
• Group by Namespace or Query
• View the Call Stack
• SOQL Optimization Tips
• Sort by SOQL or DML, Duration, Selectivity, Aggregates, Row Count
• Copy or Export to CSV

🔍 Global Search

Search across all visualizations:

• Timeline
• Call Tree
• Analysis
• Database

Quickly step through matches, auto-expand parents, and automatically show timeline tooltips.

🎨 Customization

Adjust event colors in settings.json:

"lana.timeline.colors": {
  "Method": "#2B8F81",
  "DML": "#285663",
  "SOQL": "#5D4963",
  ...
}
