Memory usage tracking over time

Severity: Recommended

Check automatically:

1. Look for memory metrics collection:

# Check for memory-related monitoring in code
grep -riE "memoryUsage|heap|rss|memory.used|process.memory" --include="*.ts" --include="*.js" src/ lib/ app/ 2>/dev/null | head -10

# Check for memory in monitoring/metrics config
grep -riE "memory|heap" --include="*.yaml" --include="*.yml" --include="*.json" monitoring/ config/ 2>/dev/null | head -10

2. Check container/orchestration memory config (implies monitoring exists):

# Docker memory limits
grep -iE "memory|mem_limit" docker-compose*.yml Dockerfile 2>/dev/null

# Kubernetes memory config
grep -iE "memory" kubernetes/*.yaml k8s/*.yaml deploy/*.yaml 2>/dev/null

3. Verify historical data available:
   • Memory graphs should show hours/days of history
   • Not just current point-in-time value

If not found in code, ask user:

• "Where can I see memory usage graphs for the app?"
• "Is memory tracked in the same tool as response times?"
• "Can you show historical memory trends (last 24h, 7d)?"

Cross-reference with:

• PERF-001 (often same monitoring tool)
• MON-001 (Section 12 - infrastructure monitoring)

Pass criteria:

• Memory usage visible over time (at minimum 24h history)
• Can see historical trends, not just current value
• Graphs show heap/RSS or equivalent memory metrics

Fail criteria:

• No memory tracking
• Only point-in-time checks (no historical graph)
• Memory only visible in container orchestrator, not application level

Evidence to capture:

• Monitoring tool used for memory
• Dashboard URL or screenshot
• Sample memory trend (24h or 7d graph)
