The Display Status mode does not affect Active Mode or Passive Mode. In other words, you can still view status information on processes regardless of whether Sentry is in Active Mode or Passive Mode as long as Display Status is selected. Active Mode-Sentry tries to restart failed processes on the host. Passive Mode-Sentry does not try to restart any processes that stop running on the host. Restart Sentry-Sentry is restarted.
