If you think that any of your service may individually fail, yes you should. For instance, the SMTP service might die without the HTTP service being affected. However, if some services are provided by a same daemon which cannot "half-fail" (eg: pop/imap), then you can enable server tracking. The principle is that only one of the service does the checks, and the other one says "track xxx/yyy" instead of "check", where "xxx" is the other instance name (the "listen" section in your case) and "yyy" the server name. That way, the tracking server will always be in the same state as the tracked server, and both will be up or down simultaneously.
