Hawkular Metrics 0.11.0 發布，改進查詢 API

Hawkular 是一個開源的監控解決方案，是 RHQ 項目 的改進版本，受益于多年的經驗，Hawkular 設計之初就考慮模塊化和可伸縮性，因此組件可在應用之外進行重用。Hawkular 可以接收來自不同源的監控數據，包括 collectd、gmond 等等。

主要改進：

1. 查詢 API 更新

• with tag filtering enabled, it is now possible add id filtering viaidparameter

• idparameter supports regex

• fromEarliestquery 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 fromnowtonow - data retention

• limitandorderparameters 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- eitherASCorDESCbased 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. 內部更新
   

• 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 & 運行
   

• 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
