The server logs told half the story. Session replay told the rest.

Infrastructure Resource Profiles with Session Replay merge two critical lenses: real-time infrastructure metrics and exact replays of user sessions. Together, they reveal not just what went wrong, but why—and exactly when infrastructure resources hit their limits.

An Infrastructure Resource Profile is a snapshot of CPU, memory, disk I/O, and network usage across your systems during a defined period. Session replay captures user actions within that same timeframe: clicks, navigation, API calls, and responses. When aligned, these tools turn isolated data into a complete operational narrative. Instead of chasing anomalies in metrics or guessing from user reports, you can pinpoint the moment a CPU spike broke the checkout flow or when bandwidth saturation stalled a dashboard load.

Optimizing infrastructure requires understanding load patterns under actual user behavior. Metrics alone show capacity trends, but they cannot map those patterns to specific workflows. By integrating Infrastructure Resource Profiles with Session Replay, you expose hidden dependencies—pages or actions that consistently trigger costly resource bursts. This insight drives precise scaling decisions, targeted caching strategies, and better load balancing.

Security and compliance also benefit. Session replay paired with resource data can verify whether suspicious traffic coincides with abnormal resource utilization. It shortens root cause analysis and tightens incident response windows. For capacity planning, historical replays layered on resource profiles predict the exact infrastructure footprint needed for upcoming releases or seasonal spikes.

The key is synchronization. Without perfectly aligned timestamps and consistent metric sampling intervals, correlation weakens. Use tools that bind infrastructure telemetry directly to session replay events with millisecond precision. This guarantees that every replay frame maps to a specific state of your servers.

Done right, Infrastructure Resource Profiles + Session Replay is not just monitoring—it’s truth. It is the difference between assuming what happened and knowing.
