Hello What kind of storage backend do you guys use if you see disk IO bottlenecks when storing ceilometer events and metrics? In my current configuration I am using 300 GB 10K SAS (in hardware raid 1) and iostat report does not look good (upto 100% unilization) with ceilometer consuming high CPU and Memory. Does it help adding more spindles and move to raid 10? Thanks! Paras. -------------- next part -------------- An HTML attachment was scrubbed...
