What is a Log Debugger?
A Log Debugger is a developer and DevOps tool used to analyze system and application logs in a structured, readable, and actionable format. Instead of raw text, logs are visualized with severity levels, timestamps, metadata, and filters that help you find issues faster.
Supported Log Formats
- Nginx Logs – access, error, and performance logs
- AWS CloudTrail – API activity and audit logs
- Azure Logs – resource and security events
- VPN Logs – authentication and connection tracking
Powerful Search, Regex, and Filters
- Full-text search across log messages
- Regex-based matching for advanced patterns
- Filter by severity (ERROR, WARN, INFO)
- Filter by service, IP, user, or action
- Sort logs by time, level, or source
Example: Nginx Log Debugging
127.0.0.1 - - [12/Dec/2024:10:45:32 +0000]
"GET /api/login HTTP/1.1" 500 234 "-" "Mozilla/5.0"
LogLens highlights this as a 500 server error, extracts the endpoint, response code, timestamp, and allows filtering all failed requests instantly.
Actionable Log View
Instead of raw text, logs are transformed into structured fields like timestamp, severity, source, message, and metadata. This allows faster debugging, better incident response, and clearer root cause analysis.
