Sourced from simpleclient's releases.

0.12.0 / 2021-08-29

This release has a (minor) breaking change in the simpleclient_hotspot module, fixing an incompatibility with OpenMetrics:

The metric jvm_classes_loaded from the ClassLoadingExports was renamed to jvm_classes_currently_loaded #681. The reason is that there is another metric named jvm_classes_loaded_total, and in OpenMetrics this resulted in a name conflict because the base name jvm_classes_loaded was the same, see prometheus/jmx_exporter#621.

[ENHANCEMENT] add support for Jakarta Servlet, implemented in the new simpleclient_servlet_jakarta module #647. Thanks @​mmadoo for the initial PR. [ENHANCEMENT] provide a way for filtering metrics by name / name prefix. This can be configured either in the HTTPServer, or in the Servlet exporter (both javax and Jakarta). For example, if some JMX metrics cause performance issues, this can be used for excluding these metrics #680. [ENHANCEMENT] for the Servlet filter (both javax and Jakarta): Add a parameter to strip the deployment path from the path label #639. Thanks @​lapo-luchini ! [ENHANCEMENT] Add HTTP Authentication to the HTTPServer #682. Thanks @​dhoard. [BUGFIX] Use <packaging>bundle</packaging> everywhere so that client_java works with OSGI again #678. Thanks @​bigmarvin. [BUGFIX] use the correct name for the metric type gaugehistogram in OpenMetrics (previously this was wrongly named gauge_histogram)

0.11.0 / 2021-05-30

[FEATURE] Exemplars: API for adding OpenMetrics Exemplars and out-of-the-box integration with OpenTelemetry tracing (#652). [ENHANCEMENT] Introduce TestContainers integration test, for example for testing different Java versions. This means you need Docker installed to run ./mvnw verify (#652). [ENHANCEMENT] HTTPServer: Set request/response timeouts (#643). [ENHANCEMENT] HTTPServer: Make HTTPMetricHandler public so that it can be used in a custom HTTPServer (#665). [ENHANCEMENT] New JVM memory metrics: jvm_memory_pool_collection_used_bytes, jvm_memory_pool_collection_committed_bytes, jvm_memory_pool_collection_max_bytes, jvm_memory_pool_collection_init_bytes, jvm_memory_objects_pending_finalization (#661, #660). [ENHANCEMENT] Version bumps (junit, jetty, maven plugins)

0.10.0 / 2021-01-25

With this release the client_java simpleclient switches to the OpenMetrics data model and adds support for various new OpenMetrics-related features. This should be largely seamless, however any counters which lack a _total suffix on their sample will now have it added. If you'd prefer to make that change more gradually, you should change your metric names before upgrading to this version.

[CHANGE] Switch data model to OpenMetrics. Primarily this means that _total if present is stripped from the metric name of counters, and _total is now always a suffix on the sample value. This means that all Counter samples now have a _total suffix (#615) [CHANGE] The io.prometheus.client.Collector.Type enum' value UNTYPED renamed to UNKNOWN (#615) [FEATURE] Add Info and Enumeration metric types for direct instrumentation (#615) [FEATURE] Counter, Summary, and Histogram metrics now expose a _created sample with when their child was created (#615) [FEATURE] Add support for units (#615) [FEATURE] Add gauge histograms, info, stateset for custom collectors (#615) [FEATURE] Support negotiating and exposing OpenMetrics for all HTTP server exposition (#615 ) [FEATURE] Add ability to filter metrics in DropwizardExports (#574) [ENHANCEMENT] Handle empty label values for the pushgateway (#553) [ENHANCEMENT] Add Bill of Materials (#561) [ENHANCEMENT] Count HTTP statuses returned for servlet filter (#560) [BUGFIX] Make sure GZIPOutputStream is always closed for httpserver (#598) [BUGFIX] Specify the charset of HTTPServer response for systems not using utf-8 by default (#564)
