New question #268156 on Graphite: https://answers.launchpad.net/graphite/+question/268156
Hello! Our Graphite server is facing CPU and disk bottlenecks. The main problem is that the %IO Wait time is always in the range of 40%. We run it on a 2-core CPU on a RHEL server with 7.5 GiB RAM. (Agreed, our CPU configuration is primitive, but we'd like to understand why the following happens before upgrading it.) Our Graphite server is processing over 160,000 data points per second. But the Disk IO stats show that 40% time is spent in IO wait. Our disk CISS can write 160 MiB per second but Graphite is only able to utilise 2MiB per second. Has anyone experienced this issue? What were your findings? Do you have any suggestions for the above questions?
