This is the rmtErrCode property of a collection-policy FSM record, the numeric error code from a remote call made while running the workflow against this stats collection policy, if that call failed. An admin uses this code to look up the specific class of remote failure that interrupted the collection-policy workflow, rather than assuming a generic error. For example, a rmtErrCode indicating an authentication failure would tell the admin the workflow failed because of a credentials problem reaching a remote component, not a bad interval value.
