Service Call Monitoring
Polaris (North Star) provides multiple monitoring metrics for service call status of running instances, such as Service Call Count and Service Request Latency, to monitor the operational status of instances and services. You can use these metrics to track Polaris's operational conditions in real time, take timely actions to address potential risks, and ensure system stability. This document explains how to view Polaris service call data through the TSF console.
