Diagnostic `nanook::cli::probe_failed`

Summary

collect failed: {0}

Help

inspect the collector's runtime config and target reachability

Details

When this fires

nanook probe built the collector successfully but the actual collect() call returned an error. The collector ran into something at runtime: target unreachable, permission denied on a sysfs path, an HTTP endpoint timing out, etc. The wrapped string is the inner collector's error rendering.

What to check

The inner message names the concrete failure. Some collectors need a warmup tick to populate state; rerun with --warmup 2s.

nanook probe --config nanook.toml --name <collector> --warmup 2s
