Describe the issue:
We are exploring using performance analyzer for developing metrics across our fleet of Opensearch clusters. We’ve setup a three node cluster and were able to bring up the cluster and performance analyzer. While going through the documentation for performance analyzer I see “IO_ReadSyscallRate” and “IO_WriteSyscallRate” and it says “system calls per second”
specifically in the description. I would like to know if this metric is specific to reads/writes requests made to Opensearch cluster or will it include all the calls made to the operating system kernel. Thanks in advance!
