config_unknown_log_format

Summary

unknown log format `{0}`

Details

When this fires

[agent.log] in nanook.toml set format = "..." to something other than text or json. The LogFormat enum (generated by the enum_label! macro in crates/nanook-core/src/config/agent.rs) only accepts those two. You'll bump into this on nanook check or nanook run startup.

What to check

text is the human-friendly tracing output; json is structured logs (one event per line, suitable for Loki / OpenSearch). Lowercase only, Json won't parse.

[agent.log]
level = "info"
format = "json"
