Simple SSH Monitor

I am trying to monitor SSH connectivity on a Mirapoint mail gateway appliance (linux based appliance). I am looking for a way to simply log into the appliance via SSH and logout, recording the reachability response time. I thought this would be a simple task as I have written much more involved linux scripts, but since this appliance doesn't support perl or python it doesn't seem that the standard linux / unix scripting will work. Any Ideas?

I mocked up an SSH "User Experience" monitor. It uses two components:

Linux/Unix Script Monitor

Command Line:

bash ${SCRIPT}

Body:

echo "Message: Test Ran Successfully"echo "Statistic: 0"

TCP Port Monitor

Port: 22

The first component is used to verify that an actual SSH connection can be initiated; unfortunately, the Linux/Unix Script Monitor does not return response time values. We add in the TCP Port Monitor because it uses Response Time as Warning/Critical Thresholds. This should get you where you need to go... If the server doesn't use bash then I would assume that you can use whichever shell is present instead and modify the script as appropriate.

You could probably even take it one step further and include a basic command that returns a known value (uname for instance) and check the exit code and/or response of the command if you want something a little less generic.
