probe_failed
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.
