Modern Linux based distributed systems generally rely on bespoke "agent" services on each node for introspecting their state or issuing operations.
In this talk I'd like to explain systemd's vision of improving and cleaning up this logic, with the ultimate goal of avoiding any local agents but nonetheless making the system nicely introspectable and accessible, with modern technologies.
For this, we'll talk about the Varlink IPC system, and the numerous Varlink APIs systemd provides these days. We'll also cover the HTTP Varlink proxy, which opens up these APIs in a web-native way, with modern authorization mechanisms. We'll also discuss systemd's metrics collection/report generation subsystem, it's cryptographic properties and remote access to it.
