NVIDIA Data Center GPU Manager (DCGM)
    Runs as a background process to manage GPUs on the node.
    Provides interface to address queries from DCGMI tool.

USAGE:
   nv-hostengine  -t -p <PORT> -d <SOCKET_PATH> -n -b <IP_ADDRESS> -c <CID> --pid <FILENAME>
                  --log-level <LEVEL> -f <FILENAME> --log-rotate --denylist-modules <MODULEID[,
                  MODULEID...]> --service-account <USERNAME> --home-dir <Diagnostic home> --
                  --version -h
Where:
  [-t | --term]:           Terminates Host Engine [Best Effort]
  [-p | --port]:           Specify the port for the Host Engine
  [-d | --domain-socket]:  Specify the Unix domain socket path for host engine.
                           No TCP listening port is opened when this option is specified.
  [-n | --no-daemon]:      Tell the host engine not to daemonize on start-up
  [-b | --bind-interface]: Specify the IP address of the network interface that the host engine should listen on.
                           	ALL = bind to all interfaces.
                           	Default: 127.0.0.1.
  [-c | --vsock-cid]:      Specify the Vsock CID that the host engine should listen on.
                           	Default: bind to any CID.
  [--pid]:                 Specify the PID filename nv-hostengine should use to ensure that only one instance
                           is running.
  [--log-level]:           Specify the logging level. Default: ERROR
                           	NONE  - Disable logging
                           	FATAL - Set log level to FATAL only
                           	ERROR - Set log level to ERROR and above
                           	WARN  - Set log level to WARNING and above
                           	INFO  - Set log level to INFO and above
                           	DEBUG - Set log level to DEBUG and above
  [-f | --log-filename]:   Specify the filename nv-hostengine should use to dump logging information.
                           Default: /var/log/nv-hostengine.log
  [--log-rotate]:          Rotate the log file if the log file with the same name already exists.
  [--denylist-modules]:    DCGM modules that should be added to the Denylist so they aren't run by the hostengine.
                           Pass a comma-separated list of module IDs like 1,2,3.
                           Module IDs are available in dcgm_structs.h as DcgmModuleId constants.
  [--service-account]:     Service account that will be used for unprivileged processes.
                           Usually this should be set to the default nvidia-dcgm account
  [--home-dir]:            The full path to the directory that the DCGM diagnostic should be launched from. This
                           becomes the default output directory for DCGM diagnostic log and stats
                           files.
  [-- | --ignore_rest]:    Ignores the rest of the labeled arguments following this flag.
  [--version]:             Displays version information and exits.
