# Cloud Insight concepts

Available in Classic and VPC

Cloud Insight allows unified management of performance and operational metrics provided by NAVER Cloud Platform services. On the Cloud Insight console, all metrics can be visualized in formats like line charts and area charts. You can also focus on specific periods by setting time ranges and manage operations via the Cloud Insight API, making it ideal for detailed monitoring. In "Cloud Insight concepts," several key concepts are explained to help effectively leverage these performance and operational metrics.

## Product

The Cloud Insight service (product) processes data differently for each product. After registering product information on Cloud Insight, you can store the corresponding product's data in the service.

              Note

              

For the list of services (products) available for managing performance and operational metrics using Cloud Insight, see [Cloud Insight prerequisites](/docs/en/cloudinsight-spec).

## CW Key

When a product is registered, a product key is issued. Product keys are used to distinguish different products. API calls are only approved when authenticated with a product-specific key issued via the Cloud Insight API. Product-specific keys can be checked in the [Cloud Insight metrics](https://api.ncloud-docs.com/docs/en/management-cloudinsight-productinfo) or retrieved by calling the [GetSystemSchemaKeyList API](https://api.ncloud-docs.com/docs/en/management-cloudinsight-getsystemschemakeylist) provided by Cloud Insight.

## Product Name

Cloud Insight processes not only data collected from NAVER Cloud Platform products, but also data generated by user applications. To distinguish NAVER Cloud Platform product data from user data, a prefix is displayed before the product name. Data from NAVER Cloud Platform products is displayed in the System/{Product Name} format, such as System/Load Balancer, System/CloudSearch, or System/Server. User-defined custom products are displayed in the Custom/{Product Name} format, such as Custom/MyProduct.

## Performance/Operational Metrics and Dimensions

Metrics refer to collected data and indicate numerical values that users wish to handle. Cloud Insight not only collects system metrics provided by NAVER Cloud Platform, but also supports user-defined custom metrics, enabling broad applicability. The following describes system metrics and custom metrics:

| Type | Subcategory | Description |
| --- | --- | --- |
| System Metric | Basic Metric | Basic performance and operational metrics provided by each NAVER Cloud Platform service, which can be directly accessed on Cloud Insight without additional configuration |
| System Metric | Extended Metric | Additional performance and operational metrics provided by each NAVER Cloud Platform service, and collection settings must be configured via the respective service console or API to access these on Cloud Insight |
| Custom Metric | - | Performance and operational metrics not provided by NAVER Cloud Platform, but collected via the Cloud Insight API from user applications or other sources |

The properties of these metrics are defined by dimensions. For instance, dimensions can specify which server a metric belongs to, its location, or what it represents. When using Cloud Insight, each product component must be designated as either a metric or a dimension.

              Note

              

For more information on metrics and dimensions for NAVER Cloud Platform products, see [Cloud Insight metrics](https://api.ncloud-docs.com/docs/en/management-cloudinsight-productinfo).

## Schema

Schema refers to the structure of collected data, consisting of metrics and dimensions.

## Aggregation functions

Most NAVER Cloud Platform services collect performance data at 1-minute intervals. Depending on user needs, data can be collected at intervals shorter or longer than 1 minute. This data is stored as raw data on Cloud Insight. Similarly, custom data is collected at intervals ideal for user needs. Collected data is periodically processed using mathematical functions, referred to as aggregation functions. Currently, Cloud Insight supports the following aggregation functions: AVG, MIN, MAX, COUNT, and SUM.

## Aggregation interval

Aggregation is performed at intervals of 1 minute, 5 minutes, 30 minutes, 2 hours, or 1 day. For example, a 5-minute aggregation processes data collected from 10:00.00 to 10:04:59, 10:05:00 to 10:09:59, and so on. The aggregated results generate AVG, MIN, MAX, COUNT, and SUM values at intervals of 1 minute, 5 minutes, 30 minutes, 2 hours, or 1 day.

              Note

              

For recommended view periods by data aggregation intervals, see [Cloud Insight prerequisites](/docs/en/cloudinsight-spec).
