Have you ever used a tech monitoring tool? If so, describe a real‑life scenario where you used it.

Situation: In my previous role as a senior backend engineer, our microservice architecture was experiencing intermittent latency spikes during peak traffic. Task: I needed to identify the root cause and ensure reliable service levels. Action: I implemented Datadog as a monitoring solution, configuring dashboards for request latency, error rates, and CPU/memory usage. I set up anomaly detection alerts and correlated logs with traces from Jaeger. By analyzing the metrics, I discovered that a database connection pool was exhausting during traffic surges. I adjusted the pool size and added circuit breakers. Result: The latency dropped from 500 ms to 120 ms on average, error rates fell by 90%, and the alerting system now proactively notifies the team before incidents occur.
