Performance Baseline Capturer Skill
Captures comprehensive performance baselines before migration to enable post-migration regression comparison and SLA verification.
Purpose
Enable performance benchmarking for:
- Response time measurement
- Throughput baseline
- Resource utilization tracking
- Load test execution
- Percentile calculation
Capabilities
1. Response Time Measurement
- Capture response times
- Measure latency percentiles
- Track by endpoint
- Document SLA targets
2. Throughput Baseline
- Measure requests per second
- Track concurrent users
- Document peak capacity
- Establish limits
3. Resource Utilization Tracking
- Monitor CPU usage
- Track memory consumption
- Measure disk I/O
- Record network usage
4. Load Test Execution
- Run baseline load tests
- Execute stress tests
- Perform soak tests
- Document results
5. Percentile Calculation
- Calculate P50/P90/P95/P99
- Track distribution
- Identify outliers
- Set thresholds
6. Regression Threshold Setting
- Define acceptable ranges
- Set alert thresholds
- Document tolerances
- Create comparison criteria
