不错！
因为现在用的opnetsdb，之前一直担忧其中存在的问题，现在版本更新也挺快，bug修复也比较及时：
Bug Fixes:
FSCK was not handling compacted and floating point duplicates properly. Now they are merged correctly.
TSMeta data updates were not loading the latest data from storage on response
The config class will now trim spaces from booleans and integers
On shutdown, the idle state handler could prevent the TSD from shutting down gracefully. A new thread factory sets that thread as a daemon thread.
TSMeta objects were not generated if multiple writes for the same data point arrived in succession due to buffering atomic increments. Increments are no longer buffered.
Updated paths to the deprecated Google Code repo for dependencies.
