Project Goal

To implement machine learning within Elasticsearch for advanced anomaly detection and root cause analysis, enhancing system monitoring and proactive issue identification.

Scope of Work

Enable and Configure ML Features in Elasticsearch:
- Enable Elasticsearch’s native ML capabilities for analytics and predictive insights.
- Configure settings for efficient data ingestion and processing within the Elasticsearch ecosystem.
Test and Validate ML Capabilities:
- Design test cases to validate the accuracy, stability, and reliability of the ML features.
- Optimize configurations to reduce computation overhead and ensure smooth operation.
Set Up Anomaly Detection Jobs:
- Create and configure anomaly detection jobs to monitor logs and metrics for unusual patterns and activities.
- Tailor detection jobs to focus on specific use cases such as error spikes, latency anomalies, or abnormal behavior in system logs.
Create Alerting Rules:
- Develop alerting mechanisms for detecting critical issues while minimizing false positives.
- Set thresholds and conditions for anomaly detection tailored to specific requirements.
Documentation:
- Document the entire setup process, including configurations, job creation, and alert settings.
- Provide a detailed guide for troubleshooting and system maintenance.
Knowledge Transfer Sessions:
- Conduct training sessions for the client’s team on:
  - Creating and managing ML jobs in Elasticsearch.
  - Adjusting detection thresholds for varying use cases.
  - Managing alerts and interpreting anomaly results.

Deliverables

Configured and operational Elasticsearch ML system for anomaly detection.
Validated and optimized anomaly detection jobs with minimal false positives.
Comprehensive documentation of the setup and configuration process.
Alerting rules integrated into the system for real-time issue identification.
Training materials and knowledge transfer sessions for the client team.

Additional Information

Elasticsearch Machine Learning (ML) Capabilities:
- In-depth understanding of Elasticsearch’s native ML features, including anomaly detection and forecasting.
Python and Relevant ML Libraries:
- Knowledge of Python scripting for custom data preprocessing and integration with Elasticsearch.
