    Last Updated:Jun 03, 2026

    Install the Cloud Monitor agent on your ECS instances, then view metrics and configure alert rules from the Host Monitoring page.

    Prerequisites

    An ECS instance is created. Create an instance.

    Step 1: Install the Cloud Monitor agent

    New ECS instances appear on the Host Monitoring page. Install the agent to start collecting metrics.

    1. Log on to the Cloud Monitor console.

    2. In the left-side navigation pane, choose Cloud Resource Monitoring > Host Monitoring.

    3. On the Host Monitoring page, find your target instance and click the image icon in the argusagent Status column.

    4. In the Confirm Automatic Installation dialog box, click OK.

      Installation takes about 5 minutes. When the agent status changes from Installation to Running, the agent is ready.

      Note

      Turn on Automatically Install CloudMonitor Agent on Newly Purchased ECS Instances in the upper-right corner to auto-install the agent on all new ECS instances.

    Step 2: View monitoring data

    View ECS instance metrics on dashboards.

    1. In the left-side navigation pane, choose Cloud Resource Monitoring > Host Monitoring.

    2. On the Host Monitoring page, click the instance name or click Monitoring Charts in the Actions column.

      ECS monitoring data covers these dimensions: OS Monitoring, Basic Monitoring, GPU Monitoring, Process Monitoring, Network Monitoring, and Cloud Disks.

      Note

      Dashboards also display ECS metrics. View the monitoring dashboard of a cloud service.

    Step 3: Enable proactive alerting

    Configure alert rules for ECS instances through proactive alerting.

    1. In the left-side navigation pane, choose Alerts > Proactive Alerting.

    2. On the Proactive Alerting page, turn on the Proactive Alerting switch for Elastic Compute Service (ECS).

      Cloud Monitor sends alerts based on default ECS alert rules.

      Note

      For custom metric-specific rules, Create an alert rule.

    Step 4: View alerting resources

    View the count of active ECS alerting resources and alert history by cloud service.

    1. In the left-side navigation pane, choose Alerts > Alerts.
