The REST API docs for ArcGIS do mention that a healthcheck URL exists at http://<host>/<instance>/rest/info/healthCheck - however I'm having an issue trying to determine what the healthCheck URL would be for the production instance that ArcGIS is hosting for us. I would think it would be something like:
https://utility.arcgis.com/usrsvcs/rest/info/healthcheck
However it doesn't appear that this works. Is there a healthcheck URL for the managed REST API?
The healthCheck is for the ArcGIS Server instance to make sure that it's accessible and can serve requests. It will fail if no machines can serve requests, whether that be if the site is not configured, the config-store isn't accessible, etc. What do you mean by "managed" REST API?
Is your deployment in AWS or Azure?
When I say "managed" I mean we did not perform the installation and host it ourselves - this is the fully managed offering by Esri. We're looking for a healthcheck on the SaaS version of ArcGIS.
