Data Visualization & Dashboards
Build real-time dashboards from modular widgets — line charts, heatmaps, pie charts, and more. Export to PDF or PNG with one click.
Chart Types
LogTrace ships with twelve chart widgets, each tuned for log-data patterns. Drag any widget onto a canvas, bind it to a query, and watch metrics update every five seconds.
Time-Series Line Chart
Plots request rate, error count, or latency percentiles over a selectable window (1 h, 6 h, 24 h, 7 d). Supports dual Y-axis and per-host color grouping. Default aggregation: 30-second buckets.
Horizontal Bar Chart
Ranks endpoints, upstream servers, or user agents by volume. Useful for spotting the top-20 slowest routes or the heaviest traffic sources at a glance.
Heatmap
Two-dimensional matrix of hours (X) vs. days (Y) with cell intensity mapped to log volume or average response time. Quickly reveals weekly traffic cycles and deployment-induced spikes.
Pie / Donut Chart
Breaks down status codes (2xx / 3xx / 4xx / 5xx), log levels, or container names by share. Donut variant shows the total count in the center label.
Gauge Widget
Single-metric indicator for CPU utilization, disk I/O, or active connections. Configurable thresholds in green / amber / red with optional Slack alert on breach.
Log Table
Paginated, sortable table of raw log lines with column filtering. Click any row to open the full JSON payload in a side drawer. Exports to CSV.
Custom Dashboards
Assemble dashboards from the widget palette, resize panels with a drag handle, and pin them to your workspace. Every dashboard is saved as a shareable URL and can be locked for read-only access.
Nginx Traffic Overview
Pre-built dashboard for Nginx access logs. Includes a 24-hour request-rate line chart, a status-code donut, a top-15 upstream bar chart, and a latency heatmap (P50 / P95 / P99). Auto-detects log format: combined, custom JSON, or Lua-structured.
Docker Container Health
Monitors container restarts, log volume per service, and error rate across a Docker Compose stack. Widgets are grouped by service name; click a service to drill into its individual log stream. Tested with Docker Engine 24.x and Docker Swarm.
Export to PDF / PNG
Render any dashboard to a print-ready PDF (A4 or landscape) or a high-resolution PNG (up to 4096 px wide). Exports include the current time window, query labels, and a LogTrace watermark. Schedule weekly PDF delivery to a team mailbox.
All dashboards respect row-level permissions: users see only the hosts and services their IAM role allows. Public links expire after 7 days unless explicitly renewed by an admin.
