Health Check

  • URL: http://<host>/<instance>/rest/info/healthCheck
  • Version Introduced:10.1


The healthcheck reports if the responding machine in the ArcGIS Server site is able to receive and process requests. For example, during site creation, this URL reports the site is unhealthy 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) site will return an HTTP 200 response code along with a message indicating "success": true (noted below). An unhealthy (unavailable) site will return messaging other than HTTP 200.


Requests to the healthCheck endpoint can always be made while output format is set to JSON. For example, in cases where the Services Directory has been disabled, requests with output format set to JSON are received and processed.
