Collect metric data from hosts

Limits

• Windows servers are not supported.
• Metric data about GPUs and hardware status cannot be collected.

Procedure

1. Log on to the Log Service console.
2. In the Import Data section, click Host Monitoring Data.
3. In the Specify Logstore step, select the project and the Metricstore that you want to use. Then, click Next.
   You can also click Create Now to create a project or a Metricstore. For more information, see Create a project and Create a Metricstore.
4. In the Create Machine Group step, create a machine group.
   • If a machine group is available, click Using Existing Machine Groups.
   • If no machine groups are available, perform the following steps to create a machine group. In this example, an Elastic Compute Service (ECS) instance is used.
     1. Select the ECS instance on which you want to install Logtail. For more information, see Install Logtail on ECS instances.
        If Logtail is installed on the ECS instance, click Complete Installation.

        Note If you want to collect data from servers in self-managed clusters or servers on third-party clouds, you must manually install Logtail. For more information, see Install Logtail on a Linux server.
     2. After Logtail is installed, click Complete Installation.
     3. Create a machine group.

        For more information about how to create a machine group, see Create an IP address-based machine group or Create a custom ID-based machine group.

5. Select the newly created machine group and move it from the Source Server Groups section to the Applied Server Groups section. Then, click Next.
   Notice If you apply a machine group immediately after it is created, the heartbeat status of the machine group may be FAIL. This issue occurs because the machine group is not connected to Log Service. In this case, you can click Automatic Retry. If the issue persists, see What do I do if no heartbeat connections are detected on Logtail?
6. In the Specify Data Source step, configure the Config Name and Plug-in Config parameters.
   inputs is required and specifies a Logtail configuration. You must configure inputs based on your data source.

   Note You can configure only one type of data source in inputs.

   {
       "inputs": [
           {
               "detail": {
                   "IntervalMs": 30000
               },
               "type": "metric_system_v2"
           }
       ]
   }

   Parameter	Data type	Required	Description
   type	string	Yes	The type of the data source. Set the value to metric_system_v2.
   IntervalMs	int	Yes	The interval between two consecutive requests. Unit: milliseconds. The value must be greater than or equal to 5000. We recommend that you set the value to 30000.

7. Click Next.
