+- [#5143](https://github.com/firecracker-microvm/firecracker/pull/5143): Fixed
+  to report `process_startup_time_us` and `process_startup_time_cpu_us` metrics
+  for `api_server` right after the API server starts, while previously reported
+  before applying seccomp filter and starting the API server. Users may observe
+  a bit longer startup time metrics.
