Host monitoring is the top priority for maintaining and managing IT systems. You can use Cloud Monitor to easily establish host monitoring capabilities. For an Elastic Compute Service (ECS) instance on which the Cloud Monitor agent is installed, you can view the monitoring data in a visualized manner on the Host Monitoring page. You can also configure alert rules for key metrics of the ECS instance by using the proactive alerting feature.
Prerequisites
An ECS instance is created. For more information, see Create instances.
Step 1: Install the Cloud Monitor agent
After you create an ECS instance in the ECS console, the ECS instance is displayed on the Host Monitoring page in the Cloud Monitor console. You must install the Cloud Monitor agent for the ECS instance before you can monitor the instance.
Log on to the Cloud Monitor console.
In the left-side navigation pane, choose .
On the Host Monitoring page, find the ECS instance and click the
icon in the argusagent Status column. In the Confirm Automatic Installation message, click OK.
The installation process requires about 5 minutes to complete. When the agent status changes from Installing to Running, the Cloud Monitor agent is installed or upgraded.
NoteYou can turn on Automatically Install CloudMonitor Agent on Newly Purchased ECS Instances in the upper-right corner. If you turn on the switch, the Cloud Monitor agent is automatically installed on newly purchased ECS instances.
Step 2: View monitoring data
You can view the monitoring data of key metrics of an ECS instance in a visualized manner.
In the left-side navigation pane, choose .
On the Host Monitoring page, click the name of the ECS instance or click Monitoring Charts in the Actions column of the ECS instance.
You can view the monitoring data of an ECS instance in the following dimensions: OS Monitoring, Basic Monitoring, GPU Monitoring, Process Monitoring, Network Monitoring, and Cloud Disks.
NoteYou can also use dashboards to view the monitoring data of ECS instances in a visualized manner. For more information, see View the monitoring dashboard of a cloud service.
Step 3: Enable proactive alerting
ECS instances support the proactive alerting feature. You can use the feature to easily configure alert rules for ECS instances.
In the left-side navigation pane, choose .
On the Proactive Alerting page, turn on Proactive Alerting next to Elastic Compute Service (ECS).
Cloud Monitor sends alert notifications to you based on the default alert rules for ECS instances.
NoteYou can also create alert rules for a metric of an ECS instance. For more information, see Create an alert rule.
Step 4: View the resources for which alerts are triggered
You can view the number of resources for which alerts are triggered on ECS instances and the alert history by cloud service.
In the left-side navigation pane, choose .
On the Cloud Services tab of the Alerts page, view the number of resources for which alerts are triggered by Elastic Compute Service (ECS).
