Dynamic Log Analysis and Anomaly Detection Toolkit

Create an advanced Bash log parsing toolkit that can process multiple log formats from different technology stacks (Java, Node.js, Python). Implement real-time anomaly detection using statistical thresholds, with the ability to trigger alerts via Slack/email when critical error patterns are detected. The script should support regex-based pattern matching, performance metrics extraction, and generate comprehensive security and performance reports. Include support for parsing compressed log files and handling large-scale distributed logging environments.
