I really don't think my problem is packet loss or anything like that - I have a hard time believing that <a href="http://127.0.0.1">127.0.0.1</a> or the public IP is unreachable of itself. It should noted that the duration is never more then a minute, sometimes 7 seconds up to 45 seconds - definitely not getting two polls in (according to what I've read it polls every 60 or 120 seconds, never quite that 7-45 second duration).
<br><br>If I ping the host from a shell I never get any packet loss or any issues, yet Hobbit still thinks it was down for a few seconds. This is <span style="font-weight: bold;">every</span> host I have monitored, by the way.
