Subject: How to find bottlenecks of the cluster ?

This is a non-sense ; you have to tell us under which conditions you want
to find a bottleneck.

Regardless the workload, we mostly use OpenTSDB to check cpu times (iowait
/ user / sys / idle), disk usage (await, ios in progress...) and memory
(numa allocations, buffers, cache, dirty pages...)
