Logging with systemd in the Raspberry Pi Cluster
summary
Demonstrates using systemd’s journal to implement centralized, structured logging over an encrypted transport on a Raspberry Pi cluster. Uses the binary systemd-journal, HTTPS with x.509 certificates, simple Python daemon programs, and a demo setup where a GPIO-button script logs to the journal and distributes shutdown commands to multiple nodes; shows exporting journal files as JSON and documents occasional corruption.
