Monitoring Metrics
Cloud Monitoring service termination notice
According to Samsung Cloud Platform’s policy, the Cloud Monitoring service is scheduled to be discontinued in September 2026.
Accordingly, from after the September 2026 release, resource monitoring of the Samsung Cloud Platform via Cloud Monitoring will no longer be possible.
With a new alternative service, you can continuously perform resource monitoring by leveraging ServiceWatch released in October 2025.
ServiceWatch provides more modern and powerful features, replacing Cloud Monitoring to deliver a seamless monitoring environment.
If you are collecting metrics and logs through the Cloud Monitoring Agent, you need to switch to the ServiceWatch Agent.
For more details about ServiceWatch, please refer to ServiceWatch Overview.
Detailed information about ServiceWatch Agent: please refer to the ServiceWatch Agent
Multi-node GPU Cluster Monitoring Metrics
The table below shows the monitoring metrics of a Multi-node GPU Cluster that can be viewed through Cloud Monitoring.
Guide
In a Multi-node GPU Cluster, users must install the Agent themselves via the guide to view monitoring metrics. Before using the stable service, please be sure to install the Agent. For instructions on installing the Agent and detailed usage of Cloud Monitoring, refer to the Cloud Monitoring guide.
