Notes and Constraints

• Istio earlier than 1.18 can only work with APM to monitor application metrics. Istio 1.18 or later can only work with AOM to monitor application metrics. Istio earlier than 1.18 can also work with AOM after being upgraded to 1.18. For a better experience, you are advised to switch APM to AOM.
• Only Istio 1.18 or later can work with LTS to collect and store access logs. To enable access logging, install log-agent on the Add-ons page in advance.
• If AOM is connected, you need to install Cloud Native Cluster Monitoring (kube-prometheus-stack) from the CCE cluster Add-ons before enabling application metrics.
