By using the VMware Integrated OpenStack profiling feature, you can enable tracing for the core OpenStack services. When enabled, tracing captures the response time of all API, RPC, driver, and database calls that are part of an OpenStack operation. You can enable or disable tracing without having to restart OpenStack services.
VMware Integrated OpenStack provides two options for configuring profiler. You can use it either with the Ceilometer OpenStack service or with vRealize Log Insight to store profiler trace data.
