Huawei all flass storage system
Average utilisation of the hardware : < 30% with stuck on 100% history syncer.
50 history syncers
Steps to reproduce:
- install and use monitoring system
- try to scale up using proxies
- use built-in functionality like aggregated items
- history syncers become at 100% load
Strace output will be full of the:
Mostly high count of trapper/history syncer processes are useless on high loaded instance due to the locking problems. Dedicated hardware is not loaded at all - so vertical scale is not happening.
The amount of processes allowed to be launched should correlate with the ability to handle workload on high performance hardware.
