    2. In the upper left hand corner, click on the Home dropdown and then Health.

 

    1. In the upper right hand corner, click on the Actions dropdown and then Run NCC Checks.

 

    1. Ensure All Checks is selected, de-select Send the cluster check report in the email, and then click on Run.

    2. Once it is green, click on the green circle, and then click on View All Tasks.

 

    1. The first line of the Tasks page should say “Health Check” – click on the Succeeded link.

 

    1. On the View Summary window, click on the Download Output link.

 

  1. Save the file to workstation.

AOS 5.0.x and Older

  1. SSH into any CVM in the cluster.
  2. Execute command: $ ncc health_checks run_all
  3. Upon completion, the health check file will be written here:
    /home/nutanix/data/logs/ncc-output-latest.log
  4. Use WinSCP (or any SCP application) to download file from the same CVM that step #2 was executed.

NCC Log Collector

AOS 5.1.x and Newer

    1. Log into Prism in web browser (Prism URL is IP of cluster virtual IP or any CVM IP)
    2. In the upper left hand corner, click on the Home dropdown and then Health.

 

    1. In the upper right hand corner, click on the Actions dropdown and then Log Collector.

 

    1. In the Run Log Collector window, choose the time period you want to gather logs for (past X amount of hours or days or a custom date/time range) and then click on Run Now.

      Try to limit the time frame down as best as possible as the log bundle can easily reach a very large size.

 

    1. After 30 seconds to 1 minute, you should see the tasks icon (circle on the main toolbar) turn blue to show it’s progress.
    2. Once it is green, click on the green circle, and then click on View All Tasks.
