This topic describes the terms of CloudMonitor.

Term Description
site monitoring A CloudMonitor feature that allows you to monitor the availability of URLs and IP addresses. You can use detection points to send requests over HTTP, HTTPS, ICMP, TCP, UDP, DNS, POP3, SMTP, or FTP to the monitored URLs or IP addresses. Then, you can obtain the status codes and response time.
cloud service monitoring A CloudMonitor feature that allows you to monitor Alibaba Cloud services. This feature allows you to monitor different cloud services for the metrics that you specify. For example, you can monitor ApsaraDB RDS, Server Load Balancer (SLB), or Object Storage Service (OSS) for the metrics that you specify.
Cloud service The services that are provided by Alibaba Cloud, such as Elastic Compute Service (ECS), SLB, and CloudMonitor.
custom monitoring A CloudMonitor feature that allows you to create custom metrics. You can add monitoring charts and configure alert rules for the custom metrics.
alert service A service that allows you to configure alert rules for metrics in host monitoring, detection points in site monitoring, instances in cloud service monitoring, and metrics in custom monitoring. If a metric meets the conditions that are specified in an alert rule, CloudMonitor sends an alert notification.
metric The type of the monitoring data. Metrics are categorized into system metrics and custom metrics. For example, the metrics of an ECS instance include the CPU utilization, memory usage, and disk usage.
dimension The identifier that is used to identify the monitoring data of a metric. For example, if you want to monitor the CPU utilization of an ECS instance, you can use the ID of the Alibaba Cloud account and the ID of the instance to identify the monitoring data.
alert rule The conditions that trigger an alert. If a metric meets the conditions specified in an alert rule, CloudMonitor sends an alert notification.
mute period The interval during which alert notifications are not sent for a metric. If a metric continuously exceeds the threshold within the specified mute period after an alert notification is sent, no more alert notifications are sent for the metric within the mute period.
alert contact A contact that receives alert notifications.
alert group A group of alert contacts that receive alert notifications. An alert group can consist of one or more alert contacts. When you create an alert rule or an application group, you must specify an alert group. When the alert threshold is reached, the system sends alert notifications to the alert contacts of the alert group based on the notification method that you specify.
notification method The method that is used to send alert notifications. The following notification methods are supported:emails and DingTalk chatbots.
carrier detection point The endpoints of China Unicom, China Mobile, and China Telecom. CloudMonitor uses carrier detection points to simulate user access behaviors and test the network quality of carriers in different regions.
alert blacklist A blacklist that includes the name of a cloud service whose alert notifications you want to block. CloudMonitor blocks alert notifications based on the specified blacklist policy.
