4. Instrument Application with Metrics

# Python Flask application with Prometheus metrics
from flask import Flask, request
from prometheus_client import Counter, Histogram, Gauge, generate_latest, REGISTRY
import time

app = Flask(__name__)

# Metrics
REQUEST_COUNT = Counter(
    'http_requests_total',
    'Total HTTP requests',
    ['method', 'endpoint', 'status']
)

REQUEST_DURATION = Histogram(
    'http_request_duration_seconds',
    'HTTP request duration',
    ['method', 'endpoint']
)

ACTIVE_REQUESTS = Gauge(
    'http_requests_active',
    'Active HTTP requests'
)

# Middleware
@app.before_request
def before_request():
    request.start_time = time.time()
    ACTIVE_REQUESTS.inc()

@app.after_request
def after_request(response):
    duration = time.time() - request.start_time

    REQUEST_COUNT.labels(
        method=request.method,
        endpoint=request.endpoint or 'unknown',
        status=response.status_code
    ).inc()

    REQUEST_DURATION.labels(
        method=request.method,
        endpoint=request.endpoint or 'unknown'
    ).observe(duration)

    ACTIVE_REQUESTS.dec()
    return response

# Metrics endpoint
@app.route('/metrics')
def metrics():
    return generate_latest(REGISTRY)

# Application endpoints
@app.route('/api/users')
def users():
    return {'users': []}

5. Performance Analysis and Troubleshooting

# Check if metrics are being scraped
curl 'http://localhost:9090/api/v1/query?query=up{job="app"}'

# Analyze request patterns
curl -G 'http://localhost:9090/api/v1/query' \
  --data-urlencode 'query=topk(10, sum by (endpoint) (rate(http_requests_total[1h])))'

# Find slow endpoints
curl -G 'http://localhost:9090/api/v1/query' \
  --data-urlencode 'query=histogram_quantile(0.99, sum by (le, endpoint) (rate(http_request_duration_seconds_bucket[5m]))) > 1'

# Memory leak detection
curl -G 'http://localhost:9090/api/v1/query_range' \
  --data-urlencode 'query=process_resident_memory_bytes{job="app"}' \
  --data-urlencode 'start=2024-01-01T00:00:00Z' \
  --data-urlencode 'end=2024-01-01T23:59:59Z' \
  --data-urlencode 'step=1h' | jq '.data.result[0].values'

# CPU spike investigation
curl -G 'http://localhost:9090/api/v1/query_range' \
  --data-urlencode 'query=rate(process_cpu_seconds_total{job="app"}[5m])' \
  --data-urlencode 'start=2024-01-01T10:00:00Z' \
  --data-urlencode 'end=2024-01-01T11:00:00Z' \
  --data-urlencode 'step=30s'

# Correlate errors with deployments (using annotations)

  -d "{
    \"time\": $(date +%s)000,
    \"text\": \"Deployed v2.1.0\",
    \"tags\": [\"deployment\", \"v2.1.0\"]
  }"

# Export metrics for analysis
curl -G 'http://localhost:9090/api/v1/query_range' \
  --data-urlencode 'query=http_requests_total' \
  --data-urlencode 'start=2024-01-01T00:00:00Z' \
  --data-urlencode 'end=2024-01-01T23:59:59Z' \
  --data-urlencode 'step=5m' | jq -r '.data.result[] | [.metric.instance, .values[][1]] | @csv' > metrics.csv
