 -   The Amazon Web Services CLI tools.  Most distributions provide these with the package name `awscli`.
 -   An actual home directory for the user you run Netdata as, instead of just using `/` as a home directory.  Setup of this is distribution specific.  `/var/lib/netdata` is the recommended directory (because the permissions will already be correct) if you are using a dedicated user (which is how most distributions work).

 -   While not mandatory, it is highly recommended to create a dedicated IAM user on your account for Netdata to send notifications.  This user needs to have programmatic access, and should only allow access to SNS.  If you're really paranoid, you can create one for each system or group of systems.
 
 Once you have all the above, run the following command as the user Netdata runs under:
