新闻 Hawkular-Metrics 0.7.0 发布 下载

Hawkular-Metrics 0.7.0 发布，此版本主要改进：counter metrics；更新的 tag 支持；性能和稳定性提升。

主要改进

1. 
   Cassandra 升级
   
   • 
     数据存储要求 Cassandra version 2.2.x
     
2. 
   更新对 counter metrics 的支持
   
   • 
     Counter raw data and rate data now support buckets similar to the way gauge data does (HWKMETRICS-280, HWKMETRICS-283)
     
     
   • 
     The same query parameters as gauge metrics are supported.
     
     
   • 
     Tagging functionality (add, delete, update) is now identical to availability and gauge metrics.
     
3. 
   Revamped tag functionality
   
   • 
     Tag support has been updated to have identical functionality across all metric types.
     
     
   • 
     Tagging data points is no longer supported; however, this functionality may resurface when requirements are better understood and there is a real use case around it (HWKMETRICS-247)
     
     
   • 
     Improved metric tag storage and querying; metric tags are no longer stored in the data table (HWKMETRICS-254)
     
4. 
   数据存储升级
   
   • 
     Schema changes will require rebuilding database
     
     
   • 
     Interval column has been removed from all tables (HWKMETRICS-3)
     
     
   • 
     Stop the warning message in Cassandra log about batch statement size threshold being exceeded (HWKMETRICS-252)
     
     
   • 
     System-wide data retention default setting is now configurable via system property (HWKMETRICS-251)
     
     
   • 
     Data retention can be set during tenant creation (HWKMETRICS-127)
     
5. 
   Influx endpoint
   
   • 
     time_precision parameter is now supported (Hawkular Metrics does not support microseconds precision though)
     
     
   • 
     integer "overflow" fixes; long integers are now used where needed
     
     
   • 
     time range restrictions support values without unit (i.e. 'time > 1010101010')
     
6. 
   PTrans
   
   • 
     logback replaces log4j as logging backend
     
7. 
   REST API documentation
   
   • 
     Improved documentation (no more broken links, more details on parameters and data types)

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。
