Note

This feature is available only for administrators and Infoblox Technical Support.

In addition to the Device UI, administrators can use additional diagnostic tools to get more visibility into individual hosts. If you are an admin user, you can execute these diagnostic tools and have the diagnostic results displayed in a browser connected to the Cloud Services Portal, with the ability to download the results. Certain diagnostic tools require certain services to be running on the host.

To run diagnostic tools on your hosts, complete the following:

  1. From the Cloud Services Portal, click Manage > Infrastructure > Hosts. 
  2. Select the check box of the host on which you want to run the diagnostic tool.
  3. Click  Host Actions > Troubleshoot, and then select one of the following tools. For each tool, you can click Download in the respective dialog to download the diagnostic results. All results are downloaded as a text file.
    • Traceroute: In the dialog, complete the following:
      • Target: Enter the target domain on which you want to execute the traceroute command. Example: csp.infoblox.com.
      • Port: Enter the port you use to communicate with the Cloud Services Portal.
      • Network Interface: Select the network interface you want to use to execute the traceroute command on the host. This allows you to capture all transmitted and received traffic over the selected interface. You can also view the routes and hops used for the host using the selected interface. Note that you can select only one interface at a time. If you do not select an interface, the traceroute command will be executed on all interfaces for the host. You cannot select a combination of interfaces.
      • Click Execute when you complete the configuration. Results are displayed in the Traceroute Results section. Note that the results support up to four hops.
    • DNS Test: The DNS Test tool is used to test the local resolver's connectivity and it's ability to resolve BloxOne Cloud endpoints. In the dialog, enter csp.infoblox.com as the Domain Name, and click Execute. Results are displayed in the DNS Test Results section. Note that this tool is used to confirm whether the BloxOne Cloud endpoints (such as csp.infoblox.com, cp.noa.infoblox.com, and others) are resolvable by the configured DNS local resolver. These domains must be resolved in order to connect to the cloud.
    • Traffic Capture: In the dialog, complete the following:
      • Timeframe: Select the timeframe for the traffic capture. A valid value is from 10 seconds to 10 minutes.
      • Source and Destination: Enter a valid IP address or FQDN for your source and target devices. These fields are optional.
      • Port: Enter the port you use to communicate with the Cloud Services Portal.
      • Service: Select the service you want to capture for the report. If you do not select any service, traffic for all services currently running on the host will be captured.

      • Network Interface: Select the network interface you want to use to execute the traffic capture operation. This allows you to capture all traffic over the selected interface. Note that you can select only one interface at a time. If you do not select an interface, the traffic capture will be executed on all interfaces for the host. You cannot select a combination of interfaces.

        Note

        Note that the troubleshoot dialog remains open until the traffic capture operation is complete. Depending on the volume of traffic, this operation might take up to 10 minutes to complete. Once the traffic capture is complete, you can click Download to download the results. 

    • NTP Test: When you select this option, the NTP test will be executed and the results displayed in the NTP Test Results section in the troubleshoot dialog. 

      Note

      Check to verify that your NTP is properly configured on your machine. If not, configure NTP prior to running the diagnostic test.

      To configure NTP on ubuntu, run the following command:

           sudo apt-get install ntp

    • Restart Host: Select this to restart the selected  host. In the confirmation dialog, click Confirm to restart a host. Only Admin users can restart a host. If your host is disconnected, you can restart the host using the host's local UI.
