But if you build or secure software, blurring the line between authentication and authorization is how you end up with a system where everyone is logged in and everyone is an admin.

Modern network operations generate an extraordinary amount of telemetry. Metrics, logs, events, topology data, cloud signals, and service context all contribute to a richer picture of system behavior. As environments expand across cloud, data center, edge, and SaaS, the opportunity for operations teams is clear: when that telemetry is unified and understood in context, it becomes a powerful source of resilience, efficiency, and business insight.

The struct is your binary record format – every field at a fixed byte offset, so you can read it back on any system that knows the layout. You use fixed-width types from stdint.h and pack(1) to strip out compiler-inserted padding. This is the advice I had always received and given, and it’s correct – as far as it goes.
