Rapidly Responds to Equipment Failure and Improves Resource Management
Use this service to continuously monitor all resources involved with your system’s operation and warn you of possible overloads, according to preset values. By preventing or quickly counteracting equipment failures and providing strategies for efficient resource performance, our management technology ensures continuous service to your users.
- Ensures Stable Operation of Computing Resources
- Through basic monitoring functions, you can receive system-related indicators, such as CPU usage rate, disk usage rate, and memory usage rate. Detailed monitoring functions, such as event settings, and comparison function per computing resource, enable effective failure analysis and quick response.
- Various information collection and detailed item settings
- 8개 분류 내 36개의 세부 항목에 대한 모니터링 성능 정보를 수집하고, 12개 분류 내 57개의 세부 항목과 관련된 이벤트 경보를 설정할 수 있습니다. 이를 통해 보다 세밀한 모니터링이 가능합니다.
- Graphs and Statistics
- You can check your monitoring data in various forms through the HTTP GET/POST method of the RESTful API. Users can directly collect and analyze real-time data as well as daily statistics through the API to be used appropriately for their businesses.
- Monitoring of various services
- You can check the state of computing resources of various services, such as Server and Auto Scaling provided by NAVER CLOUD PLATFORM. Additional features are planned to be added later on for quick response on mobile applications, such as logs and linking designated metrics.
- Customized monitoring
- You can create and operate the charts and dashboards in the desired format. Also, by dividing and monitoring servers by group, you can quickly check the status of the interested resource and quickly respond to failures.
- Simple Event Settings
- A simple template allows you to change various event-related settings with a click of a button. Designed with an intuitive UI, the Event Configuration Templates help you to manage thresholds and notifications quickly and easily.

Monitoring Dashboard
The monitoring dashboard compiles essential information about your network on a single screen for maximum efficiency. The dashboard displays the status of events occurred and terminated during a day, the status of events occurred over the past week, and the status of the top 5 servers by item for those with monitoring configured. With the dashboard, you can continuously monitor the status of the server in operation and conveniently check a specific server of your choice. To further increase the efficiency of system operation, you can easily use the dashboard data to track displayed issues in greater detail and track occurring issues.
Set Monitoring Parameters
Up to 8 categories and 36 items are available for monitoring (for some items, only event notification settings are available). By default, status information for 10 of the 36 items is provided, enabling detailed analysis. You can change the 10 items to suit the needs of your business. A chart comparison function is provided to allow you to select specific servers you want to compare and compare them by item. This is useful for checking differences between servers to identify problems or issues. It is also convenient when identifying servers that have a large difference in monitoring indicators in particular items compared to other servers.
Customizable dashboard
The 'My Chart' feature allows you to create your own customized charts and dashboards so you can see the performance information of the instances in real-time. The 'My Group' feature allows you to group your instances to efficiently monitor your primary and interest servers and react quickly in the event of a failure. In addition, the user-customized charts and dashboards are provided in the form of widgets to allow users to check desired information easily.
Event Setting Log
The event setting log shows you the history of your event settings for the last month. To prevent the improper use of the service, you can check the monitoring usage of the user of their event setting details, set date, responsible personnel, and access IP.
Event Setting Template
You can easily manage frequently-used information, such as events and receivers, in a template form. Save a template in advance so you can quickly apply it to a newly-added instance for a fast event setting.
Auto Scaling Group Monitoring
Auto Scaling group monitoring averages the set parameters of servers within a group to provide a monitoring service.
Events can be set for 6 categories (CPU, memory, load average, network, disk I/O, and the file system) and 15 items.
Using the API
You need to get an OAuth authentication key to use the API. An API authorization key can be issued and managed from My Page in the portal. The API is executed with the RESTful API type HTTP GET/POST method call. The API enables you to create various monitoring management features.
