It's time I give something back to the community.
This project, GitHub - SergeCaron/observium_appliance: Build and maintain an Observium appliancehttps://github.com/SergeCaron/observium_appliance, is aimed at SMB environments and walks the sysadmin through each phase of creating and maintaining (backup, restore, upgrade) an Observium appliance.
It also covers the installation of Let's Encrypt certificates, secure (https) access to the Observium web site, basic email configuration for notifications, and log aggregation.
It's basically a recipe with scripts. A small appliance with fault tolerant network configuration is shown to emphasize the standalone nature of the project. Of course, any virtual environment can do ;-)
I hope I kept the typos and omissions to a minimum.
Regards,
Serge Caron
