Health Check

  • URL: -or-
  • Version Introduced:10.4


The health check reports if the responding Portal for ArcGIS machine is able to receive and process requests. For example, before creating the portal, the health check URL reports the site is unavailable because it can't take requests at that time.

This endpoint is useful if you're setting up a third-party load balancer or other monitoring software that supports a health check function.

A healthy (available) portal machine will return an HTTP 200 response code along with an HTML page indicating the portal machine is ready. An unhealthy (unavailable) portal machine will return messaging other than HTTP 200.
