CloudMonitor provides you with an overview of cloud service resource usage, alarms, important events, and resource usage.  It gives you real-time updates on resource occupancy, usage level, and alarms for each cloud service.

Cloud service overview

The Cloud service overview provides a summary of the resources engaged by the hosts (like ECS and non-ECS hosts on which mainly, CloudMonitor plugin has been installed), Server Load Balancer, EIP, ApsaraDB for RDS, OSS, CDN, ApsaraDB for  MongoDB, ApsaraDB for Redis, Message Service, Container Service, Log Service, StreamComputer, Analytic DB, API Gateway, E-MapReduce, HybridDB for MySQL, ExpressConnect, and ApsaraDB for HybridDB.  This helps you to know the asset conditions immediately.

You can view Cloud Service Monitoring list page for the corresponding product, once you click cloud service resource quantity tab.

Note
To collect ECS instance CPU, memory, and disk usage data, you must install the CloudMonitor plugin.  Follow the Plugin installation guide to install CloudMonitor plugin.

Alarm overview

The alarm overview provides alarm statistics for the past seven days. It mainly includes real-time data for the following: Total number of alarm notifications Total number of triggered alarm rules Alarm rules with insufficient data Alarm SMS usage situation for the current month

You can click on the number of active alarm rules for more information.  By clicking on the number of alarm rules with insufficient data, you can view more information.

Event overview

Event overview summarizes all the defects and O&M events that occur during the span of 24 hours.   Following are the important events that support various products.

Product Name Event name
Host Plug-in stops
ApsaraDB for RDS  Master/Backup switchover
ApsaraDB for RDS  Instance fault
ApsaraDB for MongoDB Instance fault
ApsaraDB for Redis Master/Backup switchover
ApsaraDB for Redis Instance fault

Resource levels

Resource levels display the overall resource usage conditions of each product in your account.  The cumulative usage in the current month is monitored and measured for OSS, CDN, and Log Service。The metrics for other products are monitored and measured in real time by using the 95th percentile method.

Resource statistical methods 95th percentile

Percentile is a term used in statistics. To find a percentile, data values are arranged in ascending order, and the corresponding cumulative percentile is calculated. Thus, the data value corresponding to a certain percentile is called the ‘xyz’ percentile.

The 95th percentile is the value of the 95th percentile.  For example, the 95th percentile for the CPU usage for all ECS instances is 34%.   For all the ECS instances, 95% of the instance CPU usage values are less than 34%.

Hence, the 95th percentile statistics show the resource consumption level for majority of cloud services.
