You can view the resource usage of a dedicated host and configure alarm rules in the CloudMonitor console. This allows you to monitor the running status of a dedicated host.

View the resource usage of a dedicated host

  1. Log on to the CloudMonitor console.
  2. In the left-side navigation pane, choose Dashboard > Dashboards.
  3. Select Dedicated Host from the Product list.
  4. Select a region and a dedicated host from the Dedicated Host list.
  5. View the resource usage of a dedicated host.
    You can view the monitoring data from the last 30 days. CloudMonitor monitors the computing, networking, and storage resources of a dedicated host. The following table describes the metrics.
    Resource type Metric Unit Description
    Computing resource UserCpuUtilization % The average CPU usage of all the ECS instances on a dedicated host
    Networking resource UserNetworkRxPPS PPS The sum of inbound packets of all the ECS instances on a dedicated host per second
    UserNetworkTxPPS PPS The sum of outbound packets of all the ECS instances on a dedicated host per second
    UserNetworkRxBandwidth bit/s The total inbound throughput of all the ECS instances on a dedicated host
    UserNetworkTxBandwidth bit/s The total outbound throughput of all the ECS instances on a dedicated host
    Storage resource UserDiskReadIOPS IOPS The total number of requests that read data from the disks of all the ECS instances on a dedicated host
    UserDiskWriteIOPS IOPS The total number of requests that write data from the disks of all the ECS instances on a dedicated host
    UserDiskWriteBPS Byte/s The total number of bytes that are read from the disks of all the ECS instances on a dedicated host
    UserDiskWriteBPS Byte/s The total number of bytes that are written from the disks of all the ECS instances on a dedicated host

Create an alarm rule for a dedicated host

You must create alarm contacts and alarm contact groups before you create alarm rules. For more information, see Create an alert contact or alert group.

  1. Move the pointer over the metric for which you want to create an alarm rule. Click the Create an alarm rule for a dedicated host icon in the upper-right corner.
  2. Associate an alarm rule with a dedicated host.
    By default, the current dedicated host is associated with the alarm rule. However, you can change the associated dedicated host.
    • Associate the alarm rule with other dedicated hosts: Select a region from the Region list. Then select one or more dedicated hosts from the Dedicated Host list.
    • Associate the alarm rule with all dedicated hosts: Select All Resources from the Resource Range list.
  3. Configure the alarm rule.
    The following table describes the parameters of a sample alarm rule.
    Section Example Description
    Alarm Rule ddhxxx-cpu The alarm rule monitors the average CPU usage of all the ECS instances on the dedicated host.
    Rule Description
    • UserCpuUtilization
    • 1-minute cycle
    • Continue for 3 periods
    • Value
    • >=
    • 80%
    If the average CPU usage of all the ECS instances on the dedicated host is greater than or equal to 80% for three consecutive 1-minute cycles, an alarm is triggered.
    Mute for 30 minutes If the alarm conditions are still met 30 minutes after the first alarm, another alarm is triggered.
    Effective Period 19:00 to 20:59 Specifies whether to issue alarms only between 19:00 and 21:00.
  4. Configure a notification method.
    1. Select a contact group from the Contact Group list. The selected contact group is displayed in the Selected Groups list.
    2. Select an alarm level.
      The alarm level determines the notification method. The following three alarm levels are supported:
      • Phone + Text Message + Email + DingTalk (Critical)
      • Test Message + Email + DingTalk (Warning)
      • Email + DingTalk (Info)
    3. Set other optional parameters.
      The following parameters are optional:
      • Auto Scaling: Specify a scaling rule that is automatically executed when an alarm is triggered.
      • The default email subject is Product Name + Metric Name + Instance ID.
      • Email Remark: Enter additional email information.
      • HTTP CallBack: Enter a URL that is accessible from the Internet. CloudMonitor sends HTTP POST requests to push alarm messages to this URL.
