## Health checks
DTR also exposes several endpoints you can use to assess if a DTR replica
is healthy or not:
* `/health`: Checks if the several components of a DTR replica are healthy, and
returns a simple json response. This is useful for load balancing or other
automated health check tasks.
* `/load_balancer_status`: Checks if the several components of a DTR replica
can be reached, and displays that information in a table. This is useful for
an administrator to gauge the status of a DTR replica.
* `/nginx_status`: Returns the number of connections being handled by the
NGINX front-end used by DTR.
* `/api/v0/meta/cluster_status`: Returns extensive information about all DTR
replicas.
