Discovering Middleware Resources

Prerequisites

• You have configured a license by referring to License Configuration.
• You have added credentials by referring to Credential Management.
• You have installed the middleware collector by referring to Plugin Management.

Procedure

1. Double-click the RDA icon on the desktop or RDA.exe in the installation directory to start the RDA client. Enter the username and password to log in to the RDA console.
2. In the navigation pane on the left, choose Discovery > Middleware.
3. Stay on the Redis tab page.
   1. Choose Actions > Add in the upper left corner of the page.

   2. Enter the required information by referring to Table 1.
      If no credentials are added in advance, click Add Credential next to the Credential box. In the expanded area, enter the credential name and token and click Save Credential. Then click OK. To learn how to add a credential, see Credential Management.

      Table 1 Parameters

      Parameter	Description
      Name	User-defined
      Connection Address	Connection IP address
      Port	Connection port
      Credential Name	User-defined
      Token	The login password of the middleware.

      

      View the added middleware in the list. The system automatically checks the credential binding status and discovers the middleware resources.

4. Click the Redis tab.
   1. Choose Actions > Add in the upper left corner of the page.

Follow-Up Operations

After a middleware is added to RDA, you can perform the following operations:

• Viewing the discovery results

  In the middleware list, locate a middleware and view the status icon in the Status column.

  • If the icon is , the resource discovery is successful. You can click the middleware name to view details about the collected middleware details.

    

  • If the icon is , the resource discovery fails.
• Viewing the cause of a discovery failure

  Hover over in the middleware status column and view the failure cause.

• Associating a credential to middleware in a batch

  If multiple middleware resources use the same credential, you can associate the credential to these resources at the same time.

  1. In the middleware list, select the resources to be associated with the same credential and click Associate Credential.
     

     This function is available only for Redis and Kafka middleware.

  2. Select an existing credential or click Add Credential to create one. Enter the credential name and token and save the credential. Then click OK.
• Rediscovering a middleware

  After handling the discovery failure, select the middleware and choose Actions > Rediscover in the upper left corner to rediscover the middleware.

• Adding a tag

  If you add a large number of middleware to RDA, you can tag them for more efficient management and search.

  1. Select the middleware to which you want to add a tag and click Actions > Manage Tags.

  2. Select one or more tags. A tag value can be empty.

     If no tags meet your requirements, click and create a tag by referring to Tag Management.

• Quick search

  On the Middleware page, you can enter search criteria in the search box to quickly search for middleware resources.
