Operational Analytics

Using operational analytics, you can review data in what’s known as Near Real-Time (NRT) as it enters your systems. This gives you immediate insights that can alert you to failures in your system before they escalate. Key Performance Indicators (KPIs) monitored during operational analytics are Mean Time to Detect (MTTD) and Mean Time to Respond (MTTR). MTTD is the time it takes from when a problem emerges to the time detection occurs. MTTR is the amount of time it takes to neutralize a threat or failure within your network environment. Having access to these business metrics allows you to make decisions that are in the best interest of your organization.
