VI Diagnostics

Finally, a diagnostic tool safe enough for live high-traffic sites.

Debugging WordPress performance usually means installing heavy profilers that crash your site or relying on vague "conflict detectors" that tell you nothing about why a problem exists.

VI Diagnostics is different. Built with a "Safe by Design" philosophy, it runs silently in the background, sampling only a fraction of your traffic to build a forensic record of what's really happening—without slowing down your users.

Key Features

• Runtime Black Record: Captures a rolling history of the last 20 requests in a high-speed ring buffer.
• Production-Safe Sampling: Instruments only ~5% of traffic by default (configurable), ensuring zero perceptible impact on server load.
• Unified Pipeline:
  • DB Monitor: Identifies slow SQL queries and the code that triggered them.
  • HTTP Monitor: Tracks external API calls that block page loads (e.g., slow payment gateways or weary license servers).
  • Hook Tracer: Pinpoints exactly which plugin function is hogging the CPU.
• Circuit Breakers: Automatically disables itself if memory usage spikes or storage limits are reached. It never crashes your site.
• One-Click Reporting: Generate plain-text diagnostic summaries instantly to share with developers or AI assistants.
