Episode 35 — Monitor What Keeps Databases Alive: Baselines, Throughput, Latency, and Utilization
This episode teaches monitoring as an evidence-driven practice built on baselines, which DS0-001 expects you to apply when deciding whether a system is healthy, degraded, or failing. You’ll learn how to define baselines for throughput, latency, connection counts, CPU, memory pressure, storage IOPS, and queue depths, then interpret deviations in terms of likely causes rather than generic “it’s slow” complaints. We’ll cover how to monitor at multiple layers, including database metrics, host metrics, and application behavior, because many incidents are cross-layer problems like a connection pool misconfiguration that looks like a database issue. You’ll practice correlating metrics during events such as traffic spikes, long-running batch jobs, and index maintenance, and you’ll learn to separate normal cyclical patterns from true anomalies that require action. Realistic examples will include latency rising while throughput stays flat, utilization spiking due to a single hot query, and memory pressure causing cache churn that looks like random slowness. By the end, you should be able to choose the best next diagnostic step based on which metric moved first and what that implies about the bottleneck.
