Use Cases
Error Debugging
Parse application logs to find errors and exceptions. Filter by ERROR severity to quickly identify issues and their timestamps.
Server Log Analysis
Analyze Apache, Nginx, or other web server logs. Extract request patterns, response codes, and identify potential security issues.
Performance Monitoring
Parse performance logs to identify slow operations and bottlenecks. Track timestamps to understand when issues occur.
Security Auditing
Review security logs for suspicious activity, failed login attempts, and access patterns. Filter by keywords to find specific events.
Log Aggregation
Combine logs from multiple sources and parse them into structured format. Export to JSON for integration with monitoring tools.
Troubleshooting
Quickly parse logs during incident response. Filter by time range and severity to understand what happened before and after issues.
Parse Server and Application Logs Online
Our free log parser tool helps you analyze server logs, application logs, and error logs instantly. Whether you're debugging production issues, monitoring performance, or conducting security audits, this tool provides structured analysis of log files. Extract timestamps, severity levels, error messages, and patterns from various log formats. All processing happens in your browser for complete privacy.
Support for Multiple Log Formats
The parser supports common log formats including Apache/Nginx access logs, JSON logs, syslog format, and custom application logs. It automatically detects timestamps in various formats including ISO 8601, Unix timestamps, and custom date patterns. The tool handles both structured and unstructured log data efficiently.
Filter and Analyze Log Entries
Filter logs by severity level (ERROR, WARN, INFO, DEBUG) to focus on specific types of entries. Use keyword filters to find log entries containing specific error messages, user IDs, or request paths. View statistics including total entries, error counts, and warning counts at a glance.
Extract Structured Data
The parser extracts structured information from log entries including timestamps, severity levels, source files, line numbers, and error messages. This makes it easy to understand log patterns and identify recurring issues. Parsed data is presented in a clear, readable format.
- Extract timestamps in multiple formats
- Identify severity levels automatically
- Parse error messages and stack traces
- Recognize IP addresses and URLs in logs
Export for Further Analysis
Export parsed log data in JSON format for use in other tools and dashboards. The structured export makes it easy to import logs into spreadsheets, monitoring tools, or custom analytics platforms. This is useful for creating reports or sharing log analysis with team members.
Privacy and Security
All log parsing happens entirely in your browser. Your log data never leaves your device, ensuring complete privacy and security. This makes the tool ideal for parsing sensitive production logs, security audit logs, or any confidential log data.
