Currently osprofiler only choose elasticsearch,
which is only supported on x86.
On other platform like aarch64 osprofiler can
not be used since no elasticsearch package.

Enable osprofiler by enable_osprofiler: "yes",
which choose elasticsearch by default.
Choose redis by enable_redis: "yes" & osprofiler_backend: "redis"
On platform without elasticsearch support like aarch64
set enable_elasticsearch: "no"
