Overview
Service Overview
ServiceWatch is a service that collects metrics, logs, and events of resources created on the Samsung Cloud Platform, monitors them, and provides various tools to offer observability of resource performance, operational status, and more.
Key Advantages
It provides the following key advantages.
- Resource Monitoring: Collects and visualizes performance metrics (e.g., CPU Usage) of resources. It also creates a dashboard that visualizes multiple metrics in one place for a quick overview.
- Alert Policy Configuration and Automatic Notifications: Users can define conditions and thresholds to create alert policies, and receive notifications when thresholds are exceeded, enabling rapid detection and response to resource status.
- Log Analysis and Storage: Collects logs generated by resources for easy retrieval and searching. Collected logs are stored in log groups, with up to 5 GB of storage provided for free. Users can set log retention policies to define retention periods, and logs older than the retention period are automatically managed.
- Cost Efficiency: ServiceWatch offers a flexible pay-as-you-go pricing model for cost-effective usage. A free tier is also provided, allowing users to try the service for free and scale to paid usage as needed.
Features Provided
The following features are provided.
- Metric Monitoring
- Metrics: ServiceWatch receives metric data from Samsung Cloud Platform services, collects and stores this data, and makes it available to users.
- Dashboard: Visualizes metrics of a single region to provide an integrated view of resources. ServiceWatch distinguishes between automatically generated service dashboards and user-created custom dashboards.
- Alert: Offers alert functionality that notifies when metrics change beyond user-defined thresholds.
- Log Monitoring
- ServiceWatch provides log management capabilities. Logs collected from Samsung Cloud Platform services are stored in log groups for management. Log retention policies can be set to control log retention periods. Users can also view and search log data via the console, and export log groups to Object Storage.
- ServiceWatch Agent
- With the ServiceWatch Agent, detailed metrics on processes, CPU, memory, disk usage, and network performance can be collected from Virtual Server, GPU Server, Bare Metal Server, etc. GPU performance metrics can also be collected. Additionally, the Agent can collect logs generated by resources. (Planned for December 2025)
- Event Monitoring
- ServiceWatch can create event rules from system events reflecting changes to resources created on Samsung Cloud Platform, allowing users to receive notifications when specific conditions are met.
Components
Metrics
Metrics refer to performance data of a system. By default, resources of services integrated with ServiceWatch provide basic monitoring based on free metrics. Additionally, services such as Virtual Server can enable detailed monitoring to provide paid metrics.
Metric data can be retained for up to 15 months (455 days). For detailed information about metrics, see Metrics.
Logs
Logs from resources such as Virtual Server, Kubernetes Engine, and other services on Samsung Cloud Platform can be collected, stored, and viewed.
For detailed information about logs, see Logs.
Events
Events represent changes in the environment from Samsung Cloud Platform services. The following are examples of events.
- An event is generated when a Virtual Server’s status changes from Stopped to Running.
- An event is generated when a new bucket is created in Object Storage.
- An event is generated when an IAM user is removed from a user group.
For detailed information about events, see Events.
Dashboards
ServiceWatch provides pre-built service dashboards for each service automatically, and users can also create custom dashboards.
ServiceWatch Agent
The ServiceWatch Agent is a software component that collects metrics and logs from Virtual Server, GPU Server, and On-Premise servers, enabling more granular monitoring of infrastructure and applications beyond the basic monitoring provided by default.
User-defined metric/log collection via the ServiceWatch Agent is currently available only for Samsung Cloud Platform For Enterprise. It will be available for other offerings in the future.
- For more details about the ServiceWatch Agent, see Custom Metrics and Logs.
