Function Overview

You can use monitoring panels to view core metrics and compare the performance data of different services.

You must create a monitoring panel before adding graphs. You can create a maximum of 20 monitoring panels.

A resource group allows you to add and monitor correlated resources and provides a collective health status for all resources. Resources of different types, alarm rules, and alarm history are managed based on the service, facilitating O&M efficiency.

The Resource Groups function supports enterprise projects. If a resource group is associated with an enterprise project, only users who have the permission of the enterprise project can view and manage the resource group.

Server monitoring performs basic monitoring, OS monitoring, and process monitoring for servers. Whether you are using ECSs or BMSs, you can use server monitoring to track various OS metrics, monitor server resource usage, and query monitoring data when faults occur.

• Basic monitoring involves metrics automatically reported by ECS, such as CPU usage. The data is collected every 5 minutes. 
• OS monitoring provides system-wide, active, and fine-grained monitoring for servers, and requires Agents to be installed on the servers that will be monitored. The data is collected every 1 minute. OS monitoring supports metrics such as CPU usage and memory usage (Linux). For details, see Services Interconnected with Cloud Eye.
• Process monitoring is used to monitor active processes on hosts. By default, the Agent collects CPU usage, memory usage, and the number of opened files of the active processes. For details, see Services Interconnected with Cloud Eye.

In event monitoring, you can query system events that are automatically reported to Cloud Eye and custom events reported to Cloud Eye through the API. You can create alarm rules for both system events and custom events. When specific events occur, Cloud Eye generates alarms for you. Events are key operations on cloud service resources that are stored and monitored by Cloud Eye. You can view events to see operations performed by specific users on specific resources, such as delete ECS or reboot ECS. For details, see Events Supported by Event Monitoring.

You can set alarm rules for key metrics of cloud services. When the conditions in the alarm rule are met, Cloud Eye sends emails, or text messages, to you, or sends HTTP/HTTPS requests to the servers. You can quickly respond to resource changes.

Cloud Eye invokes the SMN APIs to send notifications to users. This requires you to create a topic and add subscriptions to this topic on the SMN console. Then when you create alarm rules on Cloud Eye, you can enable the alarm notification function and select the created topic. When an exception occurs, Cloud Eye can send the alarm information to the subscriptions in real time.

The Alarm Rules function supports enterprise projects. If an alarm rule is associated with an enterprise project, only users who have the permission of the enterprise project can view and manage the alarm rule.

If you need to perform fine-grained permission management on Cloud Eye, you can use IAM to:

• Create IAM users for employees based on your enterprise's organizational structure. Each IAM user will have their own security credentials for accessing Cloud Eye resources.
• Grant only the permissions required for users to perform a task.
• Entrust a HUAWEI CLOUD account or cloud service to perform efficient O&M on your Cloud Eye resources.

Cloud Eye is a multi-dimensional resource monitoring platform. You can use Cloud Eye to monitor the resource usage and cloud service status. You can also configure alarm rules for the system to notify you of alarms, if any, so that you can quickly respond to ensure service running.

You can call APIs to perform operations on metrics, alarm rules, and monitoring data, such as querying the metric list and the alarm rule list, creating alarm rules, and deleting alarm rules. For details about all supported operations, see API Overview.

If you plan to access Cloud Eye through an API, ensure that you are familiar with Cloud Eye concepts. For details, see What Is Cloud Eye?
