Plain-integer, JSON-serializable copy of Counters for the FFI/UI.

Fields

stat_fetch_failures: u64

Times a per-entry size/mtime stat fetch failed.

usn_batches_truncated: u64

Times a USN batch was truncated (records dropped before apply).

snapshot_load_failures: u64

Times a snapshot failed to load (fell back to a full scan).

snapshot_save_failures: u64

Times a snapshot failed to save.

deferred_names_unresolved: u64

Times a deferred $ATTRIBUTE_LIST name could not be resolved.

corrupt_mft_records: u64

Times a corrupt MFT record was encountered and skipped.

journal_rescans: u64

Times the USN journal was rescanned from scratch (gap recovery).

scan_pipeline_fallbacks: u64

Times the scan pipeline fell back to a slower path.

offset_table_rebuild_fallbacks: u64

Times the query-layer offset table had to be rebuilt as a fallback.

lazy_perm_rebuild_fallbacks: u64

Times a lazy permutation had to be rebuilt as a fallback.

compaction_aborts: u64

A compacted copy was discarded because the index mutated under it — impossible while the volume thread is the only writer; nonzero means that invariant broke somewhere.

pipe_malformed_frames: u64

Pipe server (fmf-service): a frame failed validation and the connection was dropped.

pipe_events_dropped: u64

Pipe server: a subscriber’s bounded event queue overflowed and the oldest event was dropped.

pipe_connections_rejected: u64

Pipe server: a client was turned away at the instance cap.

deferred_name_cache_overflow: u64

Scan: the extension-record name cache hit its capacity; remaining deferred names fall back to per-record disk reads.

deferred_name_read_failures: u64

Scan: a deferred-name disk read failed (the entry keeps a placeholder name until the next rescan).

pipe_results_evicted: u64

Pipe server: a result handle was LRU-evicted at the per-connection cap; its next page fetch answers STALE(“evicted”).

trace_serialize_failures: u64

QueryTrace JSON serialization failed; the response carried an empty trace (the query itself succeeded).

walk_read_errors: u64

Scope walk (ADR-0024): paths skipped because they could not be read.

walk_depth_truncated: u64

Scope walk: subtrees not descended because they hit the depth cap.
