You can use Telegraf to collect metric data from Redis servers. Then, you can use Logtail to send the metric data to a Metricstore in Log Service. This way, you can monitor the metric data of Redis servers in a visualized manner. This topic describes how to collect metric data from a Redis server by using Log Service and visualize the data.


  • Telegraf is installed on a server that is connected to the Redis server over an internal network.
  • A project and a Metricstore are created. For more information, see Create a project and Create a Metricstore.


Only Linux Logtail V0.16.48 and later can collect Redis metric data. If an earlier version of Logtail is installed on your server, you must update Logtail to a supported version. For more information, see Update Logtail online.


  1. Log on to the Log Service console.
  2. On the Monitoring Data tab in the Import Data section, click Redis Monitoring Data.
  3. Select the project and Metricstore and 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 Create.

        For more information, see Install Logtail on ECS instances.

        • 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.
        • After you manually install Logtail, you must configure a user identifier for 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 the Name parameter 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 identifier-based machine group.

  5. Select the new machine group from Source Server Groups and move the machine group to Applied Server Groups. Then, click Next.
    Important If you apply a machine group immediately after you create the machine group, the heartbeat status of the machine group may be FAIL. This issue occurs because the machine group is not connected to Log Service. To resolve this issue, 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 parameters. The following table describes the parameters.
    Configuration NameThe name of the Logtail configuration. You can enter a custom value.
    Cluster NameThe name of the Redis cluster. You can enter a custom value.

    After you configure this parameter, Log Service adds a cluster=Cluster name tag to the Redis monitoring data that is collected by using the Logtail configuration.

    Important Make sure that the cluster name is unique. Otherwise, data conflicts may occur.
    Server ListThe information about the Redis database. The information includes the following configuration items:
    • Address: the address of the Redis database. You can enter the IP address, hostname, or domain name of the server that hosts the database.
    • Port: the port number of the Redis database. Default value: 6379.

    You can add information about multiple Redis databases based on your business requirements.

    PasswordIf authentication is configured for the Redis database, you must enter the password of the Redis database.
    Custom TagsThe custom tags that are added to the collected Redis monitoring data. The tags are key-value pairs.

    After you configure this parameter, Log Service adds the custom tags to the Redis monitoring data that is collected by using the Logtail configuration.


How can I check whether Telegraf collects data as expected?

You can check the logs of the /etc/ilogtail/telegraf/telegraf.log file on your server. You can also collect this log file to Log Service and search for the required information.

What to do next

  • Query and analyze data

    After you configure the settings, Telegraf uses Logtail to upload collected metric data to the specified Metricstore in Log Service. You can query and analyze the data on the Query & Analysis page of the Metricstore. For more information, see Query and analyze metric data.

  • Visualize query and analysis results

    After you configure the settings, Log Service automatically creates a dashboard named Redis Monitoring Data_<cluster name> in the related project. You can visualize query and analysis results on the dashboard. You can also configure alert rules for the dashboard.
