This topic describes the general guidelines that you can follow to troubleshoot any problem with NSX for vSphere.

  1. Go to the NSX Dashboard and see if there are any errors or warnings displayed for a component. You can also go to the System Scale Dashboard to view information about the current system scale and the configuration maximums for the supported scale parameters.
  2. Go to Monitor tab of the primary NSX Manager, and see if there are any triggered system events. For more details on system events and alarms, refer to NSX Logging and System Events.
  3. Use the GET api/2.0/services/systemalarms API to view alarms on NSX object. For more information on API, refer to NSX API Guide.
  4. Use the NSX Host Health Check command to check health of a specific host.
  5. If your dashboard is indicating that a host is not in a healthy state, you can capture packets for that particular host for further troubleshooting. You can capture packets using the Packet Capture tool, to help diagnose and solve network related problems.
  6. If your problem is not resolved, download the technical support logs using the Support Bundle tool, and contact VMware support. See "How to file a Support Request in My VMware". You can either download the support bundle or can directly upload the bundle to a remote server. For more information on how to download support bundle, refer NSX Administration Guide.
