LanceDB (through Lance core) publishes metrics (currently object store request counts, bytes, latency, errors, and throttles) through the Rust ``metrics`` facade. This module installs a process-global recorder that aggregates them and registers OpenTelemetry observable instruments that report the aggregated values into the user's ``MeterProvider``. The bridge is generic: every metric LanceDB describes is surfaced automatically, with no per-metric Python code. Histograms have no asynchronous OpenTelemetry instrument, so each is exported Prometheus-style as cumulative ``le`` buckets plus ``_count`` and ``_sum`` observable counters. ) annotationsN) TYPE_CHECKINGOptional)lancedb_metrics_catalog!register_lancedb_metrics_recordersnapshot_lancedb_metrics) MeterProviderFc ddlm m}t st j ddytry |xs|}|jd }d fd }d fd }d fd }tD]w}|jxsd} |jdk(r;|j|j||jg| |j^|jdk(r;|j|j||jg| |j|jdk(s|j|jd||jg|jd|j|jd||jdg|jd|j|jd||jdg| |jdzd ay #t$r}td|d}~wwxYw)aRegister LanceDB metrics as OpenTelemetry observable instruments. Installs a process-global metrics recorder and creates one observable instrument per LanceDB metric on the given (or global) ``MeterProvider``. The user's configured ``MetricReader`` then collects them on its own schedule. Counters and gauges map directly to observable counters/gauges. Each histogram is exported as cumulative ``le`` bucket counts (``_bucket``, with an ``le`` attribute) plus ``_count`` and ``_sum``. Parameters ---------- meter_provider : opentelemetry.metrics.MeterProvider, optional The provider to register instruments on. Defaults to the global provider from ``opentelemetry.metrics.get_meter_provider()``. Returns ------- bool ``True`` if the recorder is installed and instruments are registered. ``False`` if a different ``metrics`` recorder is already installed in this process (``metrics`` permits only one global recorder), in which case a warning is emitted and no instruments are created. Notes ----- Requires the OpenTelemetry API (``pip install lancedb[otel]``) and, to actually export, an OpenTelemetry SDK (``pip install opentelemetry-sdk``) configured by the application. Calling this more than once is safe; instruments are created only on the first successful call. r) Observationget_meter_providerzinstrument_lancedb_metrics requires the OpenTelemetry API/SDK. Install it with `pip install lancedb[otel]` or `pip install opentelemetry-sdk`.NzCould not install the LanceDB metrics recorder: another `metrics` recorder is already installed in this process. LanceDB metrics will not be exported via OpenTelemetry.) stacklevelFTlancedbcfd}|S)NctDcgc]:}|jk(r)|j|j|j<c}Scc}wN)r namevalue attributes)_optionspointr metric_names Q/home/oem/CyberBrain26-unified/.venv/lib/python3.12/site-packages/lancedb/otel.pycallbackzEinstrument_lancedb_metrics..scalar_callback..callback`sN67::,1HEKK)9)9: s?Arrr s` rscalar_callbackz3instrument_lancedb_metrics..scalar_callback_s cfd}|S)Ncg}tD]d}|jk7s |j|jD]7\}}t|j}||d<|j ||9f|S)Nle)r rbucketsdictrappend)r observationsrr" cumulativerr rs rrzEinstrument_lancedb_metrics..bucket_callback..callbackjsL13 M::, 0E&+mmMNB !%e&6&6!7J')Jt$ '' J (KLM M rrrs` rbucket_callbackz3instrument_lancedb_metrics..bucket_callbackis rcfd}|S)Ncg}tD]C}|jk7rt|}|"|j||jE|Sr)r rgetattrr%r)rr&rrr fieldrs rrzDinstrument_lancedb_metrics..field_callback..callbackxs`L13 N::,u-$ '' E5;K;K(LM  N  rr)rr,rr s`` rfield_callbackz2instrument_lancedb_metrics..field_callbackws rcounter) callbacksunit descriptiongauge histogram_bucketz (cumulative buckets))r0r2_countcountz (count)_sumsumz (sum))rstr)rr:r,r:)opentelemetry.metricsr r ImportErrorrwarningswarn _INSTRUMENTED get_meterrr1kindcreate_observable_counterrr2create_observable_gauge) meter_providerr excprovidermeterrr(r-descr1r s @rinstrument_lancedb_metricsrI#sHI - .  1  5!3!5H   y )E  ()#yyB 99 !  + + *49956 ,, ,  YY' !  ) ) *49956 ,, *  YY+ %  + +99+W%*49956#//00EF ,   + +99+V$)$))W=>#//09 ,   + +99+T")$))U;<#//07 , =#JM C  /   sG** H3 G??Hr)rDzOptional['MeterProvider']returnbool)__doc__ __future__rr=typingrr_lancedbrrr r;r r?rIrrrrPsI #* 3 15G-G Gr
