Pure Frontend · Apache/Nginx Log Parser · PV/UV Stats
Zero Dependencies · Works OfflineWhat Does the Access Log Analyzer Do?
The Access Log Analyzer is a pure frontend tool for parsing Apache and Nginx server access logs. Paste log content or drag-and-drop a log file to quickly get PV/UV statistics, status code distribution, top URL rankings, source IP rankings, request method distribution, and hourly request trends. All data is processed locally in your browser — log content is never uploaded to any server, ensuring your server information stays secure.
Core Features
- Smart Format Detection: Auto-detects Apache Combined Log and Nginx default formats, no manual configuration needed
- PV/UV Statistics: Accurately calculate page views and unique visitors based on IP deduplication
- Status Code Distribution: Visual breakdown of 2xx/3xx/4xx/5xx status codes
- Top 10 URLs/IPs: Quickly identify high-traffic paths and anomalous sources
- Hourly Trends: 24-hour request distribution bar chart to identify traffic peaks
How to Use
Step 1: Paste Apache/Nginx access log content in the input area, or drag a .log file to the upload zone.
Step 2: Click "Analyze" or use Ctrl+Enter. The tool auto-detects the log format and parses it.
Step 3: View statistics including PV/UV, status codes, top URLs/IPs, and hourly trends.
Step 4: Click "Copy Report" or "Download Report" to save results. Shortcut: Ctrl+Shift+C.
Use Cases
Ops Monitoring
Quickly analyze server access logs to understand traffic patterns and detect anomalous requests for capacity planning and security auditing.
SEO Analysis
Track URL access volumes, identify high-traffic pages and 404 errors, optimize site structure and content strategy.
Security Auditing
Discover abnormal high-frequency IPs and large volumes of 4xx/5xx requests to quickly identify potential attacks.
Performance Tuning
Analyze hourly request trends to identify peak traffic periods for cache strategy and server scaling decisions.
Extended Knowledge
Apache Combined Log Format: %h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i". %h is remote host, %t is timestamp, %r is request line, %>s is status code. Nginx default format is similar. Common status codes: 200 OK, 301/302 redirect, 404 Not Found, 500 Server Error. PV (Page View) counts page views; UV (Unique Visitor) deduplicates by IP.
FAQ
Which log formats are supported?
Apache Combined Log Format and Nginx default log format, with auto-detection.
Will my log data be uploaded?
No. All parsing and analysis happens in your browser. Log data never leaves your device.
How large a log file can I analyze?
Recommended max 10MB (~100K lines). Larger files may cause browser slowdown. Analyze in batches.
Can it analyze real-time logs?
This tool analyzes pasted or uploaded log content, not real-time streaming logs.
What metrics are available?
PV, UV, status code distribution, top 10 URLs, top 10 IPs, request method distribution, hourly request trends.
Can I drag and drop log files?
Yes. Drag .log files directly into the input area to load and analyze them.
