The zugorum package provides a server for making requests to external sites in order to test liveness, and publishing the results as Prometheus metrics.

• Check the liveness of external sites and publish Prometheus metrics.
• A small, easily auditable codebase.
• Platform independence. No platform-dependent code is included in any form, and installations can largely be carried between platforms without changes.
• OCI-ready: Ready to run as an immutable, stateless, read-only, unprivileged container for maximum security and reliability.
• OSGi-ready.
• JPMS-ready.
• ISC license.
