Description
The ELK Stack enables the collection, processing, and visualization of log and system-generated data in real-time. With Elasticsearch as the search engine, Logstash for data processing, and Kibana for visual representation, it optimizes the analysis of large data volumes and enhances decision-making.
✔Benefits
- Enables faster error detection.
- Enhances fraud monitoring.
- Provides dynamic data visualizations.
✖Limitations
- Requires initial data adjustment.
- Can have high resource requirements.
- May not perform well with very large data volumes.
Trade-offs
Metrics
- Throughput
Measures the number of requests or transactions per unit of time.
- Response Time
Measures the time taken by the system to respond to requests.
- Error Rate
Measures the percentage of failed requests.
