v1.1.5

Notable changes

#1421 If using the ElasticMeterRegistry, any existing metrics_template template needs to be deleted when upgrading so it can be recreated with the fix included in that change.

---

See the 1.1.5 milestone for full details on what was included in this release. All changes from the 1.0.11 release were also included in 1.1.5.

v1.0.11

NOTE: This is the last planned patch release of the 1.0.x version line. Please upgrade to a supported release line to get future patches.

---

See the 1.0.11 milestone for details on changes included in this release.

v1.1.4

See the 1.1.4 milestone for included changes. 1.0.10 changes are also included in this release.

Notable changes

Default PauseDetector

The default PauseDetector has been changed to NoPauseDetector from ClockDriftPauseDetector (see #1324). To restore the prior behavior, configure a ClockDriftPauseDetector on your MeterRegistry like:

registry.config().pauseDetector(new ClockDriftPauseDetector(Duration.ofMillis(100), Duration.ofMillis(100));

Fail fast on missing required configuration

MissingRequiredConfigurationException will be thrown when instantiating MeterRegistry implementations if required configuration values are not available from the given *Config class used.

v1.1.0

Enhancements

New registries

• Added new registry implementations for monitoring systems:
  • AppOptics
  • Azure Monitor
  • Dynatrace
  • Elastic
  • Humio
  • KairosDB
  • Stackdriver
  • Sysdig StatsD
• Added a LoggingMeterRegistry that formats metrics as logs periodically.

New meter binders

• Jetty server thread pool metrics.
• Thread state metrics to JvmThreadMetrics.
• PostgreSQL metrics.
• Disk space metrics.
• Log4J 1.2 metrics.
• Kafka consumer metrics.
• Enhance ExecutorServiceMetrics to record time between task submission and task execution start time.

Spring Boot 1.5.x legacy module improvements

• Support management.metrics.tags.* in Spring Boot 1.5.x.

• Autoconfigure Hibernate metrics.

Other improvements

• Added support for buffering StatsD metrics using Nagle's algorithm.
• Add support for MultiGauge, a helper to spawn a series of gauges from a table-like structure that share a name but vary in tags. MultiGauge allows the set of gauges to grow and shrink over time, provided the total set of tags is well-bounded over time.
• Add support for Meter removal (MeterRegistry#remove(Meter.Id) and MeterRegistry#remove(Meter)) and a new MeterRegistry#config().onMeterRemoved(Consumer) method.
• Meter registration memory and CPU performance improvements.
• Support for strong reference gauges.
• Support for defining gauges from Supplier<T>.
• Add "outcome" tag to WebMVC and Jersey metrics that summarizes the HTTP status as informational, success, redirection, client error, server error, or unknown.
• Reduce default push-based registry logging level to DEBUG and add a single INFO-level log message that indicates the push frequency on startup.
• Upgrade to Dropwizard 4.x for Graphite/JMX.
• Eliminate Dropwizard dependency for Ganglia, instead publishing directly through the Ganglia Java client.
• Add a new overload Timer#start() that uses the default system clock.
• Allow for injection of HTTP interface into push-based registries (e.g. DatadogMeterRegistry.builder(..).httpClient(CUSTOM_HTTP_CLIENT).build().
• Drop Autocloseable from Meter and MeterRegistry to improve static code analysis experience (e.g. Sonar).
• Added structural pattern matching for meters (Meter#match(..) and Meter#use(..))
• Make HierarchicalNameMapper injectable for GraphiteMeterRegistry.
• Add exception handling for TimedAspect.
• Add base units to several binders. (Breaking change for Prometheus. See #1063)

Fixes

• Properly handle infinity values in gauges.
• Remove invalid DEFAULT from some MeterRegistryConfig subclasses (when a default isn't possible because there is a required property).
• Always convert Strings to byte array using UTF-8.
