log-analysis

Parse application logs to identify errors, performance issues, and security anomalies. Common error search : HTTP error codes : Time-based analysis : IP-based analysis : Response time analysis : Traffic volume analysis : Suspicious patterns : - Supports multiple log formats including Apache, Nginx, application logs, and JSON with grep-based pattern matching - Covers error debugging, performance analysis (response times, throughput), security audits (SQL injection, XSS, brute force), and incident response - Includes pre-built grep patterns for HTTP error codes, time-based analysis, IP-based traffic analysis, and suspicious access patterns - Read-only operations with built-in masking for sensitive data like passwords and tokens - Error debugging : analyze the root cause of application errors - Performance analysis : analyze response times and throughput - Security audit : detect anomalous access patterns - Incident response : investigate the root cause during an outage - Set time range : clearly define the time window to analyze - Save patterns : script common grep patterns - Check context : review logs around the error too ( -A , -B options) - Log rotation : search compressed logs with zgrep as well - Perform read-only operations only - Mask sensitive information (passwords, tokens) - Do not modify log files - Do not expose sensitive information externally - grep manual - awk...
