Logs can be gathered by running the following shell script on the relevant machine:

Shell script to gather logs and system information

#!/bin/bash

# This script is used to gather information about the HW and SW of the system, in addition to information about the AI Manager and the AI Plugin.
# The information is stored in a directory located in ~/nxai_info and then compressed into a file named ~/nxai_info.tgz.

# Enable debug mode
# set -x

# Create directory where the information will be stored
current_dir=$(pwd)
info_dir=~/nxai_info
rm -rf $info_dir >/dev/null 2>&1
rm -rf $info_dir.tgz >/dev/null 2>&1
mkdir -p $info_dir

# Redirect all output and error streams to a log file
log_file="$info_dir/nxai_info.log"
exec > >(tee -a "$log_file") 2>&1

This will create a file called nxai_info.tgz in the home directory. Attaching this file to your support question will make it much easier for us to help you.
