Pull request overview
Adds new Grafana panels to the search dashboard to visualize the new FTS 8.1.0 “vector indexes loaded in memory” metrics (GPU and CPU), using the repo’s dashboard templating metadata format (_base, _targets).
Changes:
- Added a panel for
fts_total_vector_indexes_in_gpu. - Added a panel for
fts_total_vector_indexes_in_cpu.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
Adds panels for runtime/heap metrics (goroutines, cgocalls, heap_alloc, heap_idle, heap_inuse, heap_released, mallocs, frees) and the new total_scan_plus_queries_kv_errors counter introduced in 8.1.0. Co-authored-by: factory-droid[bot] <138933559+factory-droid[bot]@users.noreply.github.com>

Adds panels to the search dashboard for the new FTS metrics introduced in 8.1.0 (per
cbft/etc/metrics_metadata.json):Go runtime / heap:
fts_num_goroutines- current number of goroutines running in the FTS processfts_num_cgocalls- total number of CGo calls made by the FTS process since startupfts_heap_alloc- bytes of allocated heap objects currently in usefts_heap_idle- bytes in idle (unused) heap spansfts_heap_inuse- bytes in non-idle heap spansfts_heap_released- bytes of physical memory returned to the OSfts_mallocs- cumulative count of heap objects allocatedfts_frees- cumulative count of heap objects freedQuery errors:
fts_total_scan_plus_queries_kv_errors- total number of KV errors encountered during scan plus queriesVector index placement (GPU / CPU):
fts_total_vector_indexes_in_gpu- total number of segmented vector indexes currently loaded in GPU memoryfts_total_vector_indexes_in_cpu- total number of segmented vector indexes currently loaded in CPU memory
