About The Access Log Parser

Access Log Parser summarizes pasted web server access logs by method, status code, IP address, and requested path. It is useful for quick traffic checks, incident notes, debugging, and spotting common error patterns.

Parsing runs locally in your browser. The parser targets common Apache/Nginx-style access log lines with quoted requests and status codes, so unsupported or mixed formats may be skipped.

How to Parse Access Logs Online

1. Paste access log lines into Access log input.
2. Click Parse Logs.
3. Review total lines, parsed lines, methods, status codes, top IPs, and top paths.
4. Use Load sample to see the expected log format.
5. Copy the summary for a ticket, report, or follow-up analysis.

Choosing Options Correctly

Input format:
Use consistent Common Log Format or Combined Log Format style lines. Mixed custom formats may need preprocessing before this quick parser can summarize them.

Common Use Cases

• Counting 4xx and 5xx status codes from a sample log block.
• Finding the most common requested paths.
• Checking whether one IP dominates a small log sample.
• Creating a concise access-log summary for incident review.

Quick FAQ

Does this parse every web server log format?
No. It supports common formats, but custom fields, proxies, and application logs may need a custom parser.

Can I paste production logs?
Avoid sensitive logs unless approved. Logs can contain IP addresses, tokens, URLs, user IDs, and private paths.

Does this replace log analytics?
No. It is a quick parser and summary tool, not indexing, alerting, retention, or investigation software.

Why are some lines skipped?
They may not match the expected format, may be truncated, or may include quoted fields the parser does not support.
