# Enable or disable status surveillance

Status surveillance generates an alert when engines change to an unknown state.

##

By default, there is no warning to administrators if the status of the engines changes to an unknown state. You can optionally activate the status surveillance feature. The status surveillance feature generates an alert if a single engine or none of the engines in a cluster do not send a status update for 15 minutes.
