The server slowed to a crawl at 2:14 a.m. No alerts fired. No logs pointed to the cause. By the time traffic returned to normal, the root problem was buried under layers of noise.
This is where Infrastructure Resource Profiles meet Session Replay. Together, they cut through that noise. Resource profiling tells you exactly how your compute, memory, storage, and network behaved at every moment. Session replay shows the real user path alongside that data. You see not only that the system slowed, but why it happened, right down to the request, the container, and the line of code.
Infrastructure Resource Profiles capture metrics across your stack — CPU saturation, memory spikes, I/O wait, disk throughput, ephemeral container churn. When you link them to Session Replay, you stop guessing. You watch the chain of events in context: the user click that triggered a burst of queries, the database connection pool that maxed out, the service instance that started throttling.
Session Replay on its own is powerful. It shows user actions, UI state changes, and client-side timings. But without infrastructure data, it’s incomplete. Infrastructure metrics without replays are worse — a stream of raw numbers without human context. Marrying the two transforms vague outages into solvable incidents.
