xdmp.hostStatus

xdmp.hoststatusxdmphoststatus

/apidoc/8.0/xdmp:host-status.xml

Returns the status of a host as a JSON node.

A host ID.

host-id

String[]

ValueIterator http://marklogic.com/xdmp/privileges/status

The information returned from xdmp.hostStatus is always computed on the host specified in the $host-id parameter, even if the call is evaluated on an App Server running on a different host. That is, when the API call is issued, MarkLogic Server communicates with the specified host for the its status and returns the status from the perspective of the specified host (not from the perspective of the host in which the XQuery API is evaluated). The individual statuses are of type ObjectNode.
