Follow the suggestions to resolve issues with Tableau Server process status. For additional troubleshooting steps based on process status viewed on the Status page, see Troubleshoot Server Processes.

Issue

When Tableau Server is configured with multiple networks cards, the Status page may report inconsistent or inaccurate process status. These potential inconsistencies and inaccuracies can result in other functionality such as alerting or notifications unreliability.

Environment

• Tableau Server 2021.2 and higher
• Tableau Server computers with multiple network cards (NICs)

Resolution

To address this problem, you can disable the second NIC, or use the following procedure to assign metrics to each NIC on the computer.

Note: Updating DNS or using local routing in the etc\hosts file to refer to the preferred IP address will not resolve this issue without also taking the following steps. For more related information, see Error "No Tableau Server user found" And "DataServiceFailure" Occur intermittently In Multiple Network Interfaces (NICs) Environment.

Assign metrics for each network interface

A metric is a way to indicate the “cost” of using a network interface. The higher the metric, the more expensive it is to use. By default in Windows, Automatic Metric is enabled, but you can manually assign metrics to each network interface to indicate which network interface is preferred. The lower a metric value the more preferred the interface is.

To manually configure metrics for a network interface:

1. In Control Panel, click Network and Internet.

2. Click Network and Sharing Center.

3. Click Change adapter settings.

4. Right-click on a network interface and click Properties.

5. Select Internet Protocol Version 4(TCP/IPv4) and click Properties.

6. On the General tab, click Advanced.

7. On the IP Settings tab, clear Automatic metric and enter the metric that you want in the Interface metric box.

   The metric indicates the cost of using the interface, so give your preferred interface a lower value than the other interface(s) on the computer.

Repeat the process for any other interfaces, giving them metrics based on their preference. The interface that Tableau Server uses should be the preferred interface and have the lowest value metric. For example, give the preferred network interface a metric of 5 and the secondary interface a value of 10.
