Use the script collect-c4000-net-stats.sh to collect packet metrics and arp
table entries. Fill out the HOSTNAME and PASSWORD fields in the shell
script with the hostname of the C4000 and the password of the admin user. This
is obviously not very secure, so exercise caution; set the permissions of the
script tightly and limit access to the machine containing the plaintext
credentials.
The collected metrics will be saved as JSON-formatted text files in directory
set in the OUTPUT_DIR environment variable. Example filenames:
my-host.net-net-stats-1671260819.json.
my-host.net-arp-table-1671260819.json.
The data within the net-stats files looks like:
