Collect Redis metrics

Procedure

1. Log on to the Log Service console.
2. In the Import Data section, click the Redis Monitoring Data card.
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, set the required parameters. The following table describes the parameters.

   Parameter	Description
   Configuration Name	The name of the Logtail configuration file.
   Cluster name	The name of the Redis cluster. After you set this parameter, Log Service adds the cluster=<cluster name> tag to your data. Note Make sure that the cluster name is unique. Otherwise, data conflicts may occur.
   Server List	Click the + icon to add the Redis server and set the required parameters: Address: the endpoint of the Redis server. Port: the port number of the Redis server. You can add multiple Redis servers based on your business requirements.
   Password	If authentication is enabled for the Redis server, you must enter the password of the Redis server.
   Custom Tags	In a MetricStore, you can create multiple Logtail configuration files. You can add custom tags that are specified in the Custom Tags field to the data that is collected based on these Logtail configuration files. Click the + icon to add a custom tag. You can add multiple custom tags. These custom tags are added to data entry.

FAQ

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.
