  --db DB              Path to rasdaemon DB
  --address ADDRESS    Address on which to expose metrics and the web interface
  --port PORT          Port on which to expose metrics and the web interface
  --collector-all      Enable/Disable collecting all errors (default: False)
  --collector-aer      Enable/Disable collecting AER errors (default: True)
  --collector-mce      Enable/Disable collecting MCE errors (default: True)
  --collector-mc       Enable/Disable collecting MC errors (default: True)
  --collector-extlog   Enable/Disable collecting EXTLOG errors (default: False)
  --collector-devlink  Enable/Disable collecting DEVLINK errors (default: False)
  --collector-disk     Enable/Disable collecting DISK errors (default: False)

Metrics

Metrics and labels are returned with the same name as used in the rasdaemon database, to avoid collisions they are prefixed with their type (aer, mc, mce, ...) By default, only AER, MC and MCE records are exported.
