ACK One Fleet Monitoring uses monitoring metrics from Alibaba Cloud Prometheus Service. It provides a monitoring dashboard for the fleet itself, including monitoring of core components such as APIServer and etcd, and GitOps monitoring such as Argo CD monitoring and ECI Pod disk monitoring. This helps you understand the real-time operational status of the fleet and its hosted Argo CD. This topic describes how to enable fleet monitoring.
Background information
As a manager of multiple Kubernetes clusters, you can use fleet monitoring to ensure the stability and efficiency of your multi-cluster environment. ACK One hosts Argo CD within the fleet to support multi-cluster GitOps management. As the number of applications increases, Argo CD–related pods may encounter issues such as out-of-memory (OOM) or out-of-diskspace (OOD). ACK One Fleet Monitoring helps you determine the resource requirements for Argo CD–related pods, when to upgrade specifications, and when anomalies occur.
