This topic describes how to configure Logtail in the Log Service console to collect data from Beats and Logstash.


  • Logtail is installed on the server that you use to collect data from Beats and Logstash. For more information, see Install Logtail on a Linux server or Install Logtail on a Windows server.
    Note Servers that run Linux support Logtail 0.16.9 or later. Servers that run Windows support Logtail or later.
  • Data is collected by using Logstash or Beats.
    • For more information about how to collect data from Logstash, visit Logstash-Lumberjack-Output.
    • For more information about how to collect data from Beats, visit Beats-Lumberjack-Output.
      The procedure in this topic describes how to use Packetbeat to collect data transmitted on the local network, and use the Logtail Lumberjack plug-in to upload the data to Log Service. Data collected by using Packetbeat is sent to Logstash, as shown in the following sample script:
        hosts: [""]

Background information

Logstash and Beats (such as MetricBeat, PacketBeat, Winlogbeat, Auditbeat, Filebeat, and Heartbeat) support the Lumberjack protocol. Therefore, Logtail can use the protocol to upload data that is collected by Beats and Logstash to Log Service.
  • You can configure multiple Lumberjack plug-ins, but these plug-ins cannot listen on the same port.
  • Lumberjack plug-ins support SSL. Data uploaded to Log Service from Logstash must be encrypted by using SSL.


  1. Log on to the Log Service console.
  2. In the Import Data section, select Custom Data Plug-in.
  3. Select the project and Logstore. Then, click Next.
  4. Create a machine group.
    • If a machine group is available, click Use 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. On the ECS Instances tab, select Manually Select Instances. Then, select the ECS instance that you want to use and click Execute Now.

        For more information, see Install Logtail on ECS instances.

        Note If you want to collect logs from an ECS instance that belongs to a different Alibaba Cloud account, a server in an on-premises data center, or a server of a third-party cloud service provider, you must manually install Logtail. For more information, see Install Logtail on a Linux server or Install Logtail on a Windows server. After you manually install Logtail, you must configure a user identifier on the server. For more information, see Configure a user identifier.
      2. After Logtail is installed, click Complete Installation.
      3. In the Create Machine Group step, configure Name and click Next.

        Log Service allows you to create IP address-based machine groups and custom identifier-based machine groups. For more information, see Create an IP address-based machine group and 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, set the Config Name and Plug-in Config parameters.
    • inputs: Required. The Logtail configurations for log collection.
      Note You can configure only one type of data source in the inputs field.
    • processors: Optional. The Logtail configurations for data processing. You can configure one or more processing methods in the processors field. For more information, see Overview.

    Data from Beats and Logstash is in the JSON format. processor_anchor is configured to expand the JSON-formatted data.

      "inputs": [
          "detail": {
            "BindAddress": ""
          "type": "service_lumberjack"
      "processors": [
          "detail": {
            "Anchors": [
                "ExpondJson": true,

                "Start": "",
                "Stop": ""
            "SourceKey": "content"
          "type": "processor_anchor"
    Parameter Type Required Description
    type String Yes The type of the data source. Set the value to service_lumberjack.
    BindAddress String No The IP address and port of the server to which data can be sent by using the Lumberjack protocol. Default value: To enable access from other hosts in the LAN by using the Lumberjack protocol, set the value to
    V1 Boolean No Specifies whether to use the Lumberjack protocol v1. Default value: false. Logstash supports the Lumberjack protocol v1.
    V2 Boolean No Specifies whether to use the Lumberjack protocol v2. Default value: true. Beats support the Lumberjack protocol v2.
    SSLCA String No The path of the Certificate Authority that issues the signature certificate. Default value: null. If you use a self-signed certificate, you do not need to specify the parameter.
    SSLCert String No The path of the certificate. Default value: null.
    SSLKey String No The path of the private key that corresponds to the certificate. Default value: null.
    InsecureSkipVerify Boolean No Specifies whether to skip the SSL security check. Default value: false. This value indicates the SSL security check is performed.

What to do next

After Logtail uploads data to Log Service, you can view the data in the Log Service console. The following content is the sample data uploaded to Log Service.
