2019-07-09 runsisiceph

性能查询请求类似如下 SQL 查询语句:

select ops, bytes, latency ... from osds where pool_id=<> osd_id=<> object_name=<> ... order by <> limit <max>


New in Nautilus: RBD Performance Monitoring

mgr: create shell OSD performance query class

mgr: update MMgrConfigure message to include optional OSD perf queries

[DNM] mgr: update MMgrReport message to include OSD dynamic key/value perf counters

osd: collect client perf stats when query is enabled

rbd: implement new ‘rbd perf image iostat/iotop’ commands
