Collecting centralized logs from NSX Manager


Firstly, we need to log in to NSX Manager using the admin credentials and execute the following command:

export host-tech-support host-id scp uid@ip:/path

With the introduction of NSX 6.2.3, VMware has come up with an export host-tech-support command, which can be executed on the NSX Manager to collect the following information. I strongly believe they will be adding more and more log collection options, since this is a centralized way of collecting the logs, but a lot depends upon the type of failure. If we encounter an NSX Manager failure scenario, centralized logging functionality is also impacted, hence it is important to understand the next plan for such scenarios, which is the whole purpose of me explaining the log collection process so far. Following is the list of logs that are included in the centralized logs as of now:

  • vmkernel and vsfwd log files

  • A list of filters

  • A list of dfw rules

  • A list of containers

  • Spoofguard details

  • Host-related information...
