Just use one of these urls:
1. Onpremise – http:// or https://<yourExternalserverURL>tools/diagnostics/diag.aspx
2. Online – https://crmorgname.crm.dynamics.com/tools/diagnostics/diag.aspx where crmorgname is your unique org name – what you normally enter to get to CRM and then use CRM, CRM4, or CRM5 per your usual settings.
