-The health check for a Consul instance defaults to "/health", which is the default locations of a useful endpoint in a Spring Boot Actuator application. You need to change these, even for an Actuator application if you use a non-default context path or servlet path (e.g. `server.servletPath=/foo`) or management endpoint path (e.g. `management.contextPath=/admin`). The interval that Consul uses to check the health endpoint may also be configured.  "10s" and "1m" represent 10 seconds and 1 minute respectively.  Example:
