Is there no page anywhere that will give something other than a 404?
You can pass it a URL, so even if it's just a login page, that would still be
fine, even if you're not logging in. [But what the heck is the point of
checking a web server on https unless you can see if it actually serves pages!
A 404 doesn't really tell you that - though I guess it does tell you the server
can issue 404's though. :) ]
I don't know what hitting a login page 20 times a minute, for example, might do
to performance on the device in your situation. It might also trigger an IDS
alert/warning.
You might see if there's some other options you can pass the executable that
would allow it to "recognize" 404's as a working setup, but unless there's that
option, I think you're stuck if you can't pass it a valid URL that won't
produce a 404.
{Big aside here: It looks a little like you're just checking the state of the
server - that it's "up" vs "down." While smokeping can do this kind if task,
it's probably better suited to something like Nagios/Zenos etc. You might
consider that. SP is best at measuring the "health" of a connection in terms of
latency and packet-loss - not at measuring state and keeping history of the
same. SP's alerting is, IMO, especially poor for that sort of thing too. It's a
performance measurement tool, not a "state" measurement tool. Using it for
state can work, but isn't optimal, IMO.}

Thanks Greg. I switched over to EchoPingHttps. In my scenario I am simply
looking to confirm that port 443 is open. There is no actual page to load at
the address though. Is there a way to ignore the 404 response and still measure
that response time to the port?

I'm not sure about the second [manual] result, but the debug shows that TCPPing
came back with:

[U] - meaning unknown.
Is it possible that the TCPPing executable isn't where you think [or somkeping]
thinks it is, and/or can't run it for some reason?
I don't think you should ever get an unknown - you should either get a result
or a loss - but unknown may be what you get if SP can't run it properly.

One other issue, I see you're hitting the 443 [HTTP-SSL] port. I'd guess this
may be part of the issue. I seem to recall issues getting TCPPing to work with
SSL sessions properly - how are you going to validate a cert etc.
For that, I think this would be more appropo:

My gut says it's the HTTPS that's the problem, but both are worth looking into.

Below is a copy of smoke ping debug output, along with the output of running
the command manually. I'm not sure why, but I'm not see numerical values
returned when running the command manually. I'm guess this is why no data is
being logged in the graph. All rrd files are owned by smokeping:smokeping and
are have perms of 755.
Any thoughts?
