新闻 Hawkular Metrics 0.11.0 发布，改进查询 API 下载

Hawkular Metrics 0.11.0 发布，此版本是个重要版本，包括查询 API 增强，metric 模块重构，支持在 Wildfly 10 上部署。

主要改进：

1. 
   查询 API 更新
   
   
   • 
     with tag filtering enabled, it is now possible add id filtering via id parameter
     
     
   • 
     id parameter supports regex
     
   • 
     fromEarliest query parameter was added to allow querying for all available data for a metric
     
     
   • 
     this allows querying all data without specifying start and end
     
     
   • 
     data retention for the metric is taken account, so the max time span is from now to now - data retention
     
   • 
     limit and order parameters are now available for raw data queries on all metric types
     
     
   • 
     limit - integer representing the maximum number of raw data points to be returned
     
     
   • 
     order - either ASC or DESC based on the timestamp of the data point
     
     
   • 
     if both are specified than limit is applied from the start of the sorted list
     
     
   • 
     for defaults and additional details please visit - Hawkular Metrics - Rest Documentation
     
   • 
     Limit and Sort Order for raw data queries (HWKMETRICS-334, HWKMETRICS-62, HWKMETRICS-51)
     
     
   • 
     Ability to query all metric raw or aggregate metric data (HWKMETRICS-331)
     
     
   • 
     Fixed the url for querying rate data across multiple metrics (HWKMETRICS-332)
     
     
   • 
     Filtering metrics by id (HWKMETRICS-234)
     
2. 
   内部更新
   
   
   • 
     this was a large effort to consolidate the internal domain model without changing any of the user APIs
     
     
   • 
     this change will help the documentation efforts for future releases as well as a consistent data structure for the REST APIs
     
   • 
     Model refactoring (HWKMETRICS-326, HWKMETRICS-323)
     
3. 
   Hawkular 集成
   
   
   • 
     The integration with Hawkular has now been updated to use asynchronous messages (HWKMETRICS-337)
     
4. 
   Wildfly 10 - 部署 & 运行
   
   
   • 
     Deploying and running the project on Wildfly 10 is now fully supported
     
     
   • 
     Support for Wildfly 9 is deprecated and will be completely dropped in the next release

Hawkular 是一个开源的监控解决方案，是 RHQ 项目 的改进版本，受益于多年的经验，Hawkular 设计之初就考虑模块化和可伸缩性，因此组件可在应用之外进行重用。Hawkular 可以接收来自不同源的监控数据，包括 collectd、gmond 等等。

Hawkular 可以让你以应用为中心的视图对整个可连接资源的架构进行监控，并可以很入到应用中某个单独资源进行浏览。
