When a service health score degrades, ITSI's Deep Dive feature allows you to investigate the root cause by drilling down from the service level to individual KPIs, entities, and raw events. Deep Dives provide a swimlane view showing multiple KPIs side-by-side over time.
By placing CPU, memory, response time, and error rate KPIs in parallel swimlanes, you can visually identify which metric spiked first. This temporal correlation distinguishes root causes from symptoms.
