Debug Token:

root@pizza1:~# cat /var/log/pihole_debug-sanitized.log
This process collects information from your Pi-hole, and optionally uploads it to a unique and random directory on tricorder.pi-hole.net.

The intent of this script is to allow users to self-diagnose their installations. This is accomplished by running tests against our software and providing the user with links to FAQ articles when a problem is detected. Since we are a small team and Pi-hole has been growing steadily, it is our hope that this will help us spend more time on development.

NOTE: All log files auto-delete after 48 hours and ONLY the Pi-hole developers can access your data via the given token. We have taken these extra steps to secure your data and will work to further reduce any personal information gathered.

As long as one of them is green, and it matches what is in /etc/pihole/setupVars.conf, there is no need for concern.

The link to the FAQ is for an issue that sometimes occurs when the IPv6 address changes, which is why we check for it.
