$ docker run cgr.dev/chainguard/prometheus-node-exporter --help
usage: node_exporter [<flags>]

Flags:
  -h, --help                     Show context-sensitive help (also try
                                 --help-long and --help-man).
      --collector.arp.device-include=COLLECTOR.ARP.DEVICE-INCLUDE
                                 Regexp of arp devices to include (mutually
                                 exclusive to device-exclude).
      --collector.arp.device-exclude=COLLECTOR.ARP.DEVICE-EXCLUDE
                                 Regexp of arp devices to exclude (mutually
                                 exclusive to device-include).
      --collector.bcache.priorityStats
                                 Expose expensive priority stats.
      --collector.cpu.guest      Enables metric node_cpu_guest_seconds_total
      --collector.cpu.info       Enables metric cpu_info
      --collector.cpu.info.flags-include=COLLECTOR.CPU.INFO.FLAGS-INCLUDE
                                 Filter the `flags` field in cpuInfo with a
                                 value that must be a regular expression
      --collector.cpu.info.bugs-include=COLLECTOR.CPU.INFO.BUGS-INCLUDE
                                 Filter the `bugs` field in cpuInfo with a value
                                 that must be a regular expression
