Setting Up WSL

Install A Distro:

Run the following in powershell as admin Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
Install a distro (ex: Ubuntu 18.04 LTS - https://www.microsoft.com/store/apps/9N9TNGVNDL3Q)
Open your distro you installed via the start menu, let it setup
Update and upgrade

sudo apt-get update

Restore access to a unifi controller

When you are unable to login to the unifi controller or forgot admin password, you can restore access using SSH and manipulating mongodb directly.

Warning

Do not uninstall unifi controller - most of the data is not stored in mongodb. In case you thought a mongodb backup would be sufficient, you may have fucked up already, just like me. However I managed to write this "tutorial" for anyone to not run into the same trap.

Apparently this guide no longer works with recent unifi controller versions (starting nov/dec 2022). Since I no longer use unifi hardware in my home system, I can not update the guide myself. In case you've gotten here to recover your data, you're likely doomed. But giving it a try won't hurt anyway, therefore: good luck.

Graphite does two things:

Store numeric time-series data
Render graphs of this data on demand

What Graphite does not do is collect data for you, however there are some tools out there that know
