SOLR-17806: Migrate AuditLoggerPlugin to OTEL (#3665)
* SOLR-17806: Migrate AuditLoggerPlugin to OTEL
* Address PR comment on InterruptedException in test
* Fix AuditLoggerPlugin description for solr_auditlogger_request_times metric
* Register Nanosecond Histogram view in SolrMetricManager
* Run gradlew tidy
* Refactor plugin_name as a shared metric category attribute
* Address part of PR feedback
* Improve description for solr_auditlogger_lost OTEL metric
* Add TODO note about making histogram buckets configurable
* Use synchronous gauge for solr_auditlogger_async_enabled metric
* Run gradlew tidy

== Metrics
-Audit logging plugins record metrics about count and timing of log requests, as well as queue size for async loggers.
-The metrics keys are all recorded on the `SECURITY` category, and each metric name are prefixed with a scope of `/auditlogging` and the class name of the logger, e.g., `SolrLogAuditLoggerPlugin`.
+The metrics keys are all recorded on the `SECURITY` category, and each metric includes attributes for the handler (e.g., `/auditlogging`) and the class name of the logger (e.g., `SolrLogAuditLoggerPlugin`).
The individual metrics are:
-* `count`: (_meter_) Records number and rate of audit logs written.
-* `errors`: (_meter_) Records number and rate of errors.
-* `lost`: (_meter_) Records number and rate of events lost if the queue is full and `blockAsync=false`.
-* `requestTimes`: (_timer_) Records latency and percentiles for audit logging performance.
-* `totalTime`: (_counter_) Records total time spent logging.
-* `queueCapacity`: (_gauge_) Records the maximum size of the async logging queue.
-* `queueSize`: (_gauge_) Records the number of events currently waiting in the queue.
-* `queuedTime`: (_timer_) Records the amount of time events waited in queue.
-Adding this with the `requestTimes` metric will show the total time from event to logging complete.
-* `async`: (_gauge_) Tells whether this logger is in async mode.
-
-TIP: If you experience a very high request rate and have a slow audit logger plugin, you may see the `queueSize` and `queuedTime` metrics increase, and possibly start dropping events (shown by an increase in `lost` count).
+* `solr_auditlogger_count_total`: (_counter_) Records number of audit logs written.
+* `solr_auditlogger_errors_total`: (_counter_) Records number of errors.
+* `solr_auditlogger_lost_total`: (_counter_) Records number of events lost if the queue is full and `blockAsync=false`.
+* `solr_auditlogger_request_times_nanoseconds`: (_histogram_) Records latency and percentiles for audit logging performance.
+* `solr_auditlogger_queue`: (_gauge_) Records the maximum size (`type=capacity`) and current size (`type=size`) of the async logging queue.
+* `solr_auditlogger_queued_time_nanoseconds`: (_histogram_) Records the amount of time events waited in queue.
+Adding this with the `solr_auditlogger_request_times_nanoseconds` metric will show the total time from event to logging complete.
+* `solr_auditlogger_async_enabled`: (_gauge_) Tells whether this logger is in async mode (1) or not (0).
+
+TIP: If you experience a very high request rate and have a slow audit logger plugin, you may see the `solr_auditlogger_queue` size metric increase, and possibly start dropping events (shown by an increase in `solr_auditlogger_lost_total` count).
In this case you may want to increase the `numThreads` setting.

(solr) 26/33: SOLR-17806: Migrate thread pool metrics to OTEL (#3519)
Posted by ml...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
mlbiscoc pushed a commit to branch feature/SOLR-17458-rebased
in repository https://gitbox.apache.org/repos/asf/solr.git
commit 63f8fccf2599f1f637c66d116a66f92aaee9aadb
Author: Jude Muriithi <90...@users.noreply.github.com>
AuthorDate: Wed Sep 17 16:16:33 2025 -0400
SOLR-17806: Migrate thread pool metrics to OTEL (#3519)
* Stub out OtelInstrumentedeExecutorService
* Finish OTEL ExecutorService implementation and replace MetricsUtil calls
* Add OtelUnits to timers
* spotlessApply
* feedback
* Use IOUtils.closeQuietly
* Check in partial tests
* Add pool metrics testing
* use utility method in tests

SOLR-17798: Integrate SDK OTLP metric exporter (#3413)
* Create dynamic SDK Meter Providers and tests
* Bad merge from feature branch
* Wrap meter providers and metric readers
* Test cleanup
* Cleanup
* Initialize a OTLP exporter
* Add Noop metric expoter
* Add test for exporter
* Create exporter factory
* Drop revert opentelemetry version upgrade
* Add some java docs
* Wrong merged conflicts

SOLR-17806: Migrate DirectUpdateHandler2 metrics to OTEL (#3417)
* Migrate direct update handler
* Fix up metrics
* UNCOMMIT ME BEFORE PUSHING
* Revert requestHandlerBase

-Welcome to Apache Solr Prometheus Exporter
-========
-
-Apache Solr Prometheus Exporter (solr-exporter) provides a way for you to expose metrics for Solr to Prometheus.
-
-# Getting Started With Solr Prometheus Exporter
-
-For information on how to get started with solr-exporter please see:
- * [Solr Reference Guide's section on Monitoring Solr with Prometheus and Grafana](https://solr.apache.org/guide/solr/latest/deployment-guide/monitoring-with-prometheus-and-grafana.html)
-
-# Docker
-
-The Solr Prometheus Exporter can be run via the official or local Solr docker image.
-Please refer to the `docker` directory's `README.md` for information on building the image
-and the [Solr Reference Guide](https://solr.apache.org/guide/solr/latest/deployment-guide/solr-in-docker.html) for information on using the image.
-
-The `solr-exporter` script is available on the path by default in the Docker image, so the Prometheus Exporter can be run using:
-
-```bash
-docker run <image> solr-exporter
-```
-
-The environment variables and command line arguments that the Prometheus Exporter accepts can be used the same way in the Docker image.

- <!--
- Templates to help reduce jq boilerplate used by many metrics in this config;
- mainly intended for metrics that don't require a bunch of jq magic to work and are mostly boilerplate.
-
- A regex with named groups is used to match template references to template + vars using the basic pattern:
-
- $jq:<TEMPLATE>( <UNIQUE>, <KEYSELECTOR>, <METRIC>, <TYPE> )
-
- For instance,
-
- $jq:core(requests_total, endswith(".requestTimes"), count, COUNTER)
-
- TEMPLATE = core
- UNIQUE = requests_total (unique suffix for this metric, results in a metric named "solr_metrics_core_requests_total")
- KEYSELECTOR = endswith(".requestTimes") (filter to select the specific key for this metric)
- METRIC = count
- TYPE = COUNTER
-
- Some templates may have a default type, so you can omit that from your template reference, such as:
-
- $jq:core(requests_total, endswith(".requestTimes"), count)
-
- Uses the defaultType=COUNTER as many uses of the core template are counts.
-
- If a template reference omits the metric, then the unique suffix is used, for instance:
-
- $jq:core-query(1minRate, endswith(".requestTimes"))
-
- Creates a GAUGE metric (default type) named "solr_metrics_core_query_1minRate" using the 1minRate value from the selected JSON object.
-
- Add templates as needed, three metrics using the same structure feels about right as the threshold for creating a new template.

Posted by ml...@apache.org.
This is an automated email from the ASF dual-hosted git repository.
mlbiscoc pushed a commit to branch feature/SOLR-17458-rebased
in repository https://gitbox.apache.org/repos/asf/solr.git
commit 046b206de34417bb672b335fe607d90dda586e39
Author: Matthew Biscocho <ml...@apache.org>

SOLR-17854: Support filters to /admin/metrics endpoint for Prometheus metrics (#3499)
* Add fitlering for /admin/metrics
* Rename vars
* Use a generic method for handling the 3 types metric types
* Optimize requiredLabelsFilter
* Add tests for MetricsHandlerTest
* Add tests around FilterablePrometheusMetricReader
* static member
* Fix tests

SOLR-17806: Migrate SolrIndexSearcher metrics to OTEL (#3482)
* Migrate SolrIndexSearcher metrics to OTEL
* renaming metrics
* metric renaming, adding descriptions
* removing comment and renaming metric
* switch to OTEL for statsCache
* recording string metric is not required
* Metrics cleanup
* Fix broken searcher tests
* Change solr_searcher_live_docs_cache to a counter
* Feedback changes
* Remove sort metric
* Remove caching enabled metric

- * <li>this class allows us to "tag" MBean instances so that we can later unregister only

- * <li>this class processes all metrics already existing in the registry at the time when reporter

SOLR-17793: Create dedicated SdkMeterProviders for Solr core metrics (#3402)
* Create dynamic SDK Meter Providers and tests
* Bad merge from feature branch
* Wrap meter providers and metric readers
* Test cleanup
* Cleanup
* Fix double lookups
* Create a separate test suite for prometheus
* Move back to registry name
* Changes from comments
