WPStack TOP Load Monitor

Core monitoring

• Captures request load, memory delta, query count, slow queries, duplicate queries, request context, and PHP errors at shutdown.
• Stores snapshots in a dedicated database table with safe, repeatable activation migrations.
• Intercepts slow SQL with execution time and caller-stack information.
• Uses configurable sampling so production teams can balance visibility and overhead.

Live visibility

• Shows a live admin-bar indicator for load time, query count, and memory without a database hit.
• Provides a real-time dashboard with metric cards, performance charts, recent requests, alerts, slow queries, errors, process breakdowns, and smart insights.
• Includes dedicated snapshot detail pages with AI summaries, timeline waterfalls, query breakdowns, error streams, and plugin attribution.
• Offers one-minute, five-minute, and fifteen-minute statistics with averages, peaks, and p95 measurements.

Native smart insights

• Builds a rolling baseline from recent snapshots and flags statistically unusual performance using z-score analysis.
• Detects N+1 query patterns fired repeatedly from the same caller.
• Generates focused recommendations for postmeta, options, terms, users, posts, and WooCommerce-related patterns.
• Ranks plugins by performance cost using hook time, slow-query time, and duplicate-query signals.
• Creates plain-language health summaries with good, warning, and critical classifications.

Optional AI assistance

• Supports NVIDIA and OpenRouter through an OpenAI-compatible API format.
• Adds enhanced root-cause summaries and actionable optimization suggestions.
• Includes a contextual chat assistant for questions such as why a page is slow or which plugin is heaviest.
• Sends no data externally unless an administrator enables and configures a provider.

Alerting, reliability, and developer tooling

• Provides configurable thresholds for load, slow queries, query count, duplicates, memory, and runtime.
• Deduplicates alerts with a five-minute cooldown.
• Uses a bounded in-memory ring buffer for fast polling and cached settings with a transient fallback.
• Includes a local Chart.js fallback when the CDN is unavailable.
• Protects REST and AJAX operations with administrator capabilities and nonce verification.
• Includes a REST API under wpstack-top/v1 for dashboard data, snapshots, timelines, insights, chat, and settings.
• Ships with internationalized interface strings and an integration test harness containing more than 70 assertions.
