Monitoring is a key attribute of SRE with the goal being to find out what is broken (or about to break) and why. If a system cannot self-heal, then an SRE should investigate the alert, identify and mitigate the issues, and determine the root cause. The priority metrics that SRE monitoring covers are: Latency Traffic Errors Saturation

Monitoring means measuring your system’s health. An SRE uses alerts, tickets, logging mechanisms, and request times to monitor a system’s health. This ensures the system is stable and minimizes user disruption. In case a bug occurs, they respond immediately to resolve it. However, doing all of this manually is expensive and time-consuming.

The Site Reliability Engineer is responsible for implementing effective monitoring solutions to track the health and performance of systems in real time. Monitoring allows them to identify anomalies and potential issues before they escalate into critical incidents.
