v1.0.5

Notice to StatsD users!

This release mistakenly failed to shade pcollections into micrometer-registry-statsd. For this patch release only, please add pcollections to your runtime classpath:

compile("io.micrometer:micrometer-registry-statsd:1.0.5")
runtime("org.pcollections:pcollections:3.0.1")

This will be resolved in 1.0.6.

Improvements

• Cache StatsD lines for each meter to limit garbage produced by StatsD implementation.
• Make JMX metrics domain configurable by property (backported from Spring Boot 2.0.3).
• Avoid uri tag explosion when use of path variable is undetected (backported from Spring Boot 2.0.3).
• Upgrade to Prometheus simpleclient_common version 0.4.0.
• Memory improvements to camel and upper camel NamingConvention implementations.
• Shutdown thread pool when closing StepMeterRegistry, an abstract base class upon which many implementations are built.

Fixes

• Sanitize Telegraf tags on export.
• HistogramSnapshot methods max(TimeUnit unit) and mean(TimeUnit unit) are appropriately scaled.
• InfluxNamingConvention doesn't apply base convention to tag values.
• GraphiteMeterRegistry passes Clock to self-created GraphiteReporter.
• Use statKeys and statValues in PrometheusMeterRegistry.newMeter().
• Corrected spelling on executor.steals metric name.
• Corrected implementation of maximumAllowableTags to only limit metrics of a particular name.
