# Micrometer 1.0.6 发布，指标监控工具

2018-07-20

Micrometer 1.0.6 已发布，Micrometer 是一个监控指标的度量类库。本次更新包括功能改进和 bug 修复，具体如下：

• Influx retention policies are now fully customizable through InfluxConfig.

• Make DataSourcePoolMetricsAutoConfiguration conditional on DataSource bean.

• Make RestTemplateMetricsConfiguration an auto-configuration.

• Make meterNamePrefix work as a prefix in MeterFilter#maximumAllowableTags.

• Fetch authorization keys for every batch post in push-based registries containing such keys (including for Datadog).

• JCacheMetrics guards against empty cache names, such as those emanating from Apache Ignite.

• Remove extra space in description text for jvm.memory.committed.

• Make step size configurable for SignalFx.

• Added support for Jersey MappableException in DefaultJerseyTagsProvider.

• Only publish on close if the registry implementation is enabled.

• Improve sanitation of name and tags for statsd to replace : characters.

• Record a non-empty tag value for anonymous Exception types thrown in Spring WebMVC endpoints.

• Fixed ConcurrentModificationException in CompositeMeterRegistry.

• Added a base unit to the id on TimeGauge.

• Fixed SLA bug that made the last two buckets always equal in count.

• When using a "maximum allowable tag values" MeterFilter, the tag values seen before the maximum is reached continue to be allowed.

• When the specified tag key was reached in "maximum allowable tag values" MeterFilter, other tag keys were affected too. This is no longer the case.

• Fixed description text that generated errors on Prometheus Pushgateway.

• Metrics.More is now public so less frequently used meter types can be constructed, e.g. Metrics.more().longTaskTimer(..).

• Filters are now only applied once for percentiles, SLAs, and other synthetic meters.

• Fixed regression in 1.0.5 that stopped converting Influx metric names to snakecase.

• Make DatadogNamingConvention#tagKey respect its delegate.

• StepTimer and StepDistributionSummary now update count and sum based on expiry.

• Shade pcollections into micrometer-registry-statsd.
