Performance Baseline Capturer Skill Skill

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
