v0.8.3

Same as v0.8.2 (just needed to fix some problems related to publishing the artifacts).

v0.8.2

Add metrics to the cloudwatch observer:

• servo.cloudwatch.metrics: number of metrics published to cloudwatch
• servo.cloudwatch.errors: number of cloudwatch errors (includes additional tag to include the error type)
• servo.cloudwatch.puts: timer that measures how long it takes to publish metrics

v0.8.1

Internal changes only:

• Switched to new build system based on gradle 2.2
• Updated aws sdk dependencies to 1.9.16
• Documentation updates
• Minor style fixes

0.8.0

• Updated aws sdk dependency to only depend on the cloudwatch and autoscaling jars.
• Replaced the majority of guava uses with internal implementations.
• Minor updates so servo can be compiled on jdk8.

0.7.9

• New DataSourceType: NORMALIZED used to indicate that a counter reports a rate per second normalized to a step boundary.
• Performance improvements to BasicTag#hashCode()
• Update slf4j and aws-java-sdk dependencies to slf4j-api:1.7.7 and aws-java-sdk:1.8.9.1

0.7.8

• Update aws sdk dependency for servo-aws to 1.8.7.
• LongGauge and DoubleGauge return the primitive value instead of the atomic number so it can be displayed by JMX viewers and the value doesn't change after it's been polled.
• (Internal) Gradle updated to 1.12.

0.7.7

• Reconnect to graphite after connection errors
• BasicTimer and BasicDistributionSummary record values that are >= 0
• Internal cleanup (checkstyle fixes + creation of servo-internal project to reduce warnings).

0.7.6

• Fixes a bug in ThreadCpuStats that prevented threads from getting deleted from the usage map.
• Adds a new monitor: BasicDistributionSummary which tracks the distribution of events. Similar to a BasicTimer without the time unit aspect.
• Compatibility for the servo-core API is now automatically checked as part of the build.

0.7.5

• Added DynamicTimer.record(MonitorConfig, TimeUnit reporUnit, long duration, TimeUnit durationUnit) that allows, for example, to report the timer value in seconds, but record the duration of the event in milliseconds.

0.7.4

• JMX ObjectNameMapper can be specified via a property com.netflix.servo.DefaultMonitorRegistry.jmxMapperClass.
• Allows the mapping from Monitor to JMX ObjectName to be configurable. Added an ordered based mapper which maps known properties in a given order, useful for tools such as VisualVM.
• Timers created by TimedInterface are no longer created lazily, and are therefore registered with JMX.
• Fixes a compatibility issue min and max gauges and basic timers where the gauges were reporting the values for the previous interval, but the counts were reported for the current interval.
