site monitoring The feature that allows you to monitor the availability of URLs and IP addresses. You can use detection points to send requests by using the HTTP, HTTPS, ICMP, TCP, UDP, DNS, POP3, SMTP, or FTP protocol to the monitored URLs or IP addresses. You can then receive the status codes and response time.
cloud service monitoring The feature that allows you to monitor Alibaba Cloud services. For example, you can monitor the metrics of ApsaraDB RDS, Server Load Balancer (SLB), and Object Storage Service (OSS).
Alibaba Cloud service The services provided by Alibaba Cloud, such as Elastic Compute Service (ECS), SLB, and CloudMonitor.
custom monitoring The feature that allows you to customize metrics. You can add monitoring charts and configure alert rules for the custom metrics.
alert service The 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 specified in an alert rule, an alert notification is sent.
metric The type of the monitoring data. CloudMonitor provides system metrics and allows you to customize 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 locate monitoring data of a metric. For example, 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, an alert notification is sent.
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 was sent, no more alert notifications are sent for the metric in this mute period.
alert contact The recipient of alert notifications.
alert group The group of alert contacts that receive alert notifications. An alert group can consist of one or more alert contacts. If you specify an alert group for an alert rule of an application group, alert notifications are sent to the contacts in the alert group by using the specified notification method.
notification method The method used to send alert notifications. Supported methods includeemails and DingTalk chatbots.
