Hawkular 开源监控解决方案
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 Metrics 0.19.0 发布了，该版本在性能和REST API方面做了全面的增强，主要包括：
REST API - Query Improvements
It is now possible to use relative timestamps when querying for data via + or - added to timestamp parameters. When used, the timestamp is relative to the local system timestamp (HWKMETRICS-358, HWKMETRICS-457)
Querying for data from earliest available data point has been expanded to raw data queries for gauges and counters (HWKMETRICS-435)
DELETE tenants/{id} has been added to allow the deletion of an entire tenant (HWKMETRICS-446)
AvailabilityType is serialized as simple string in bucket data points (HWKMETRICS-436)
Performance Enhancements
The write performance has been increased by 10% across the board after reorganizing the meta-data internal indexes. (HWKMETRICS-422)
GZIP replaced LZ4 as the compression algorithm for the data table. This produces anywhere between 60% to 70% disk usage savings over LZ4. (HWKMETRICS-454)
Job Scheduler - Improvements
The newly introduced internal job scheduler received several improvements and fixes; the main focus was to enhance the scalability and fault tolerance.
The job scheduler will be used only for internal tasks.
