You can call this end point to retrieve the org memory usage
http://apidocs.cloudfoundry.org/222/organizations/retrieving_organization_memory_usage.html

You would then need to check this against the org quota.

There's a story further down in the backlog for a similar endpoint for
space.

There was a previous PR to add end points that would more clearly show
quota usage for org and space, but it fell through.

Hi,

doing some tests, I detected in my testing environment the following
scenario:

Error: the string "{\n \"code\": 100005,\n \"description\": \"You
have ex
ceeded your organization's memory limit.\",\n \"error_code\":
\"CF-AppMemoryQuo
taExceeded\"\n}\n" was thrown, throw an Error :)

Does exist some REST Call to know if the org/space has reached the limit?

Many thanks in advance

Juan Antonio
