Details

When this fires

Error::Adapter in crates/nanook-core/src/error.rs is the umbrella variant for runtime failures inside an adapter (the things that ship metrics outward, like prometheus, statsd, dogstatsd). The named target is the adapter's config name; the wrapped source describes what went wrong (a downstream connection drop, a serializer error, a credential rejection). Only emitted while nanook run is going; static option problems show up under the nanook::config::* codes instead.

What to check

The wrapped source error names the cause. For TLS / auth failures, double-check credentials and any token-bearing env vars referenced via ${...}. The adapter-specific page under docs/content/docs/adapters/ lists exact opts and gotchas.
