Represents the set of supported metric property names for Node.js process and runtime monitoring.
Each property corresponds to a specific metric:
event_loop_delay_milliseconds: Measures the event loop delay in milliseconds.event_loop_utilized: Indicates the proportion of time the event loop is active.heap_used_bytes: The number of bytes used in the V8 heap.heap_total_bytes: The total size of the V8 heap in bytes.rss_bytes: Resident Set Size, the total memory allocated for the process.external_bytes: Memory used by C++ objects bound to JavaScript objects managed by V8.array_buffers_bytes: Memory allocated for ArrayBuffers and SharedArrayBuffers.process_start_time_seconds: The process start time in seconds since the Unix epoch.process_cpu_user_seconds_total: Total user CPU time spent by the process in seconds.process_cpu_system_seconds_total: Total system CPU time spent by the process in seconds.process_cpu_seconds_total: Total CPU time (user + system) spent by the process in seconds.process_pid: The process identifier (PID).
