GSLB Overview
What Global Server Load Balancing is in Elchi — DNS-based traffic steering with active health probing, a quad-state health model, and a CoreDNS plugin that consumes a zone-authenticated DNS snapshot API.

The GSLB Statistics dashboard — probe success rate, IP health distribution, error breakdown, latency and success-rate timelines, and the worker/timewheel/write-buffer internals, filtered per controller and time range.
The GSLB probe and health model — HTTP/HTTPS/TCP probes, the quad-state PASSING/WARNING/CRITICAL/RECOVERY model, anti-flapping, circuit-breaker backoff, and how state drives which IPs are served in DNS.
The elchi-coredns GSLB nodes — how CoreDNS consumes the zone-authenticated DNS snapshot API, node tracking and cleanup, proxied health/records, and single-node vs. broadcast notify.
Managing GSLB DNS records and the IPs behind them — create, update, bulk enable/disable, add/remove IPs, assign regions, override health state, and clear status history.
