Dashboard Overview

The LoadFlux dashboard is a React application served at your configured path (default /loadflux). It has six pages accessible from the sidebar.

Dashboard (Home)​

Dashboard Home

The main page shows a real-time overview:

  • Request rate — RPS (requests per second) and RPM (requests per minute)
  • Response time — Average, P95, and P99 latency
  • Error rate — Percentage of 4xx/5xx responses
  • Status breakdown — 2xx, 4xx, and 5xx counts
  • Top endpoints — Highest traffic routes (1h window)
  • Slowest endpoints — Routes with highest P95 latency (1h window)
  • Highest error rate — Routes with the most errors (1h window)
  • Server info — Node.js version, platform, PID, active SSE connections

All data on this page updates in real-time via SSE (every 2 seconds).

System​

System Metrics

System resource monitoring with time-series charts:

  • CPU usage — Percentage over time
  • Memory — Used vs total RAM
  • Disk — Used vs total space (where available)
  • Network I/O — Bytes received/transmitted (Linux only; macOS/Windows show N/A)

Use the time range selector to view data from the last hour to 90 days.

Endpoints​

Endpoints

Detailed API endpoint analytics:

  • Top endpoints by requests — Most-hit routes
  • Top endpoints by latency — Slowest routes (by average duration)
  • Slow requests — Requests exceeding the slow threshold (default 500ms)
  • Endpoint metrics table — Full breakdown with request count, error count, and latency percentiles

App Metrics​

App Metrics

Node.js process health:

  • Heap usage — V8 heap used vs allocated
  • Event loop delay — Average and max delay in milliseconds
  • GC pauses — Garbage collection pause duration
  • Uptime — How long the server has been running (real-time from SSE)

Errors​

Errors

Error tracking and analysis:

  • Status distribution — Doughnut chart of 2xx/3xx/4xx/5xx responses
  • Error log — Table of individual error responses with timestamp, method, path, status code, error message, and duration

Settings​

Settings

Dashboard configuration:

  • Retention — View and change how many days of data to keep
  • Slow threshold — Adjust the millisecond threshold for slow requests
  • Export — Download metrics data as JSON for a selected time range (1 hour to the configured retention period)

Theme​

Toggle between dark and light mode using the theme switch in the sidebar. The dashboard respects your system preference by default.

Time Range Selector​

Most pages include a time range selector with preset options:

  • Last 1 hour
  • Last 6 hours
  • Last 24 hours
  • Last 7 days
  • Last 30 days
  • Last 90 days

Select a range to query historical data from the database.
