We have some Omega iServers (http://www.omega.com/pptst/iTHX-W3.html) in our environment that we'd like to track statistics of three sensors, Temp., Humidity, Dewpoint.

The company has an Excel based logging solution, but we nor they can get it to work. Ideally I think PRTG would be the best solution. But I can't get it to pull the variable data.

I've tried HTTP gets but I'm not smart enough to get it to work.

Does anyone have experience with these products?

Here is a link to the product manual: http://www.omega.com/Manuals/manualpdf/M4965.pdf The provide HTTPget info on page 39 & 40.

When I use their httpget utility it works as expected: ie: httpget -r -S *SRH\r from cmd prompt returns the results.

Any advice would be appreciated.

http http-get snmp

PRTG needs the data which is coming from a EXE file in the following format:

exit code

Where value can be any float or integer and message can be any string up to a length of 1024 characters.
API documentation can be found here
I assume your EXE just provides the value, so you might wrap the same up in a batch script which provides the additional data like message and exit code.
I also noticed that the device seems to support SNMP, so you might as the vendor for a MIB file for the device and just import the same to PRTG. Then you just could use SNMP Library Sensors.

I recently had a user purchase some of these Omega units, and I wanted to pull the data into PRTG. I created (3) bat files (one each for temp, humidity, and dewpoint) , and placed the in the correct folder.

Here's one I use for humidity:

set str1=httpget.exe -r -S *SRH\r %1:2000 for /f "delims=" %%r in ('%str1%') do set var1=%%r

set /a n1=%var1:1,2% set /a n3=%n1%*1 set str2=:ok echo %n3%%str2%

You name it something like 'humidity.bat', then use it in a custom sensor. Information is located here: https://www.paessler.com/manuals/prtg/exe_script_sensor

Also, I placed the httpget.exe file in the custom sensors folder, along with the script.

Thanks for sharing that one, Joe! Although the thread is somewhat old, it might be helpful for others :)
