CloudMonitor provides you with an overview of your cloud services, cloud resource usage, alarms, and important events, allowing you to understand the utilization and maintenance of your resources and the alarms for your cloud services in real time.

Cloud service overview

The cloud service overview provides a summary of the resources that you use, helping you quickly and easily understand the assets you have. The cloud service overview displays the following services:
  • Hosts, including ECS hosts and the non-ECS hosts that are installed with the CloudMonitor agent
  • Server Load Balancer
  • Elastic IP Address
  • ApsaraDB for RDS, MongoDB, Memcache, and Redis
  • OSS
  • CDN
  • Message Service
  • Container Service
  • Log Service
  • StreamCompute
  • Analytic DB
  • API Gateway
  • E-MapReduce
  • HybridDB for MySQL
  • HybridDB for PostgreSQL
  • Express Connect

By clicking the number of resources, you can view the list page for the corresponding services under cloud service monitoring.

Note To monitor and view ECS data (such as CPU, memory, and disk usage), you need to install the CloudMonitor agent. For more information about how to install the CloudMonitor agent, see Install CloudMonitor agent.

Alarm overview

The alarm overview provides alarm statistics, including the total number of alarms for the past seven days, the number of currently triggered alarm rules, the number of alarm rules with insufficient data, and the alarm SMS usage for the current month.

You can view more information by clicking the number of alarms or alarm rules.

Event overview

Event overview summarizes all the exceptions and O&M events that occur during a span of 24 hours. The following are important events that are supported.

Product Event
Host Agent stops working.
ApsaraDB for RDS  Master/Backup switchover
ApsaraDB for RDS  Instance failure
ApsaraDB for MongoDB Instance failure
ApsaraDB for Redis Master/Backup switchover
ApsaraDB for Redis Instance failure

Resource usage overview

Resource usage shows the overall resource usage of each service under your account. The cumulative usage in the current month is monitored and measured for OSS, CDN, and Log Service. The metrics for all other services are monitored in real time by using the 95th percentile method. For example, if the 95th percentile for the CPU usage of ECS instances is 34%, 95% of the ECS instances have a CPU usage of less than 34%. The value that is determined by this method varies by product.
