VMware Exam 3V0-41.22 Topic 5 Question 2 Discussion

To enable logging for the production NSX-T environment, you need to follow these steps:

Verify via putty with SSH that the administrator can connect to all NSX-Transport Nodes. You can use the credentials identified in Putty (admin) to log in to each transport node. For example, you can use the following command to connect to the sfo01w01en01 edge transport node: ssh admin@sfo01w01en01. You should see a welcome message and a prompt to enter commands.

Verify that there is no current active logging enabled by reviewing that directory is empty -/var/log/syslog-. You can use the ls command to list the files in the /var/log/syslog directory. For example, you can use the following command to check the sfo01w01en01 edge transport node: ls /var/log/syslog. You should see an empty output if there is no active logging enabled.

Enable NSX Manager Cluster logging. You can use the search_web('NSX Manager Cluster logging configuration') tool to find some information on how to configure remote logging for NSX Manager Cluster. One of the results is NSX-T Syslog Configuration Revisited - vDives, which provides the following steps:

Navigate to System > Fabric > Profiles > Node Profiles then select All NSX Nodes then under Syslog Servers click +ADD

Enter the IP or FQDN of the syslog server, the Port and Protocol and the desired Log Level then click ADD

Select multiple configuration choices that could be appropriate success criteri

a. You can use the search_web('NSX-T logging success criteria') tool to find some information on how to verify and troubleshoot logging for NSX-T. Some of the possible success criteria are:

The syslog server receives log messages from all NSX nodes

The log messages contain relevant information such as timestamp, hostname, facility, severity, message ID, and message content

The log messages are formatted and filtered according to the configured settings

The log messages are encrypted and authenticated if using secure protocols such as TLS or LI-TLS

Enable NSX Edge Node logging. You can use the search_web('NSX Edge Node logging configuration') tool to find some information on how to configure remote logging for NSX Edge Node. One of the results is Configure Remote Logging - VMware Docs, which provides the following steps:

Run the following command to configure a log server and the types of messages to send to the log server. Multiple facilities or message IDs can be specified as a comma delimited list, without spaces.

set logging-server <hostname-or-ip-address [:port]> proto level <level> [facility <facility>] [messageid <messageid>] [serverca <filename>] [clientca <filename>] [certificate <filename>] [key <filename>] [structured-data <structured-data>]

Validate logs are generated on each selected appliance by reviewing the '/var/log/syslog''. You can use the cat or tail commands to view the contents of the /var/log/syslog file on each appliance. For example, you can use the following command to view the last 10 lines of the sfo01w01en01 edge transport node: tail -n 10 /var/log/syslog. You should see log messages similar to this:

2023-04-06T12:34:56+00:00 sfo01w01en01 user.info nsx-edge[1234]: 2023-04-06T12:34:56Z nsx-edge[1234]: INFO: [nsx@6876 comp='nsx-edge' subcomp='nsx-edge' level='INFO' security='False'] Message from nsx-edge

You have successfully enabled logging for the production NSX-T environment.
