Performance Monitoring
Response time tracking, memory monitoring, and leak detection
This guide walks you through auditing a project's performance monitoring capabilities, covering response time tracking and memory management.
The Goal: Proactive Performance Visibility
Performance issues should be detected and diagnosed before users notice. Complete monitoring coverage means you see slowdowns, memory growth, and resource pressure as they develop.
- Per-endpoint — response time monitoring identifies slow requests at the route level
- Historical — memory usage tracked over time enables capacity planning and trend analysis
- Alerting — automated detection of memory leaks before they cause outages
- Protected — heap dump capabilities secured from unauthorized access
Before You Start
- Identify the monitoring stack (Datadog, New Relic, Prometheus/Grafana, Sentry Performance, etc.)
- Get access to monitoring dashboards if external
- Understand the deployment environment (containers, serverless, VMs)
memory-monitoring
Track memory usage with historical trends visible
“Is your memory usage trending up month over month?”
Automated alerts for memory growth or threshold breaches
“Will you know about a memory leak before your users do?”
Protected mechanism to capture heap dumps for debugging memory leaks
“Could anyone trigger a heap dump from the internet right now?”
