I have followed the Hyperic instructions on how to create a custom script and have Hyperic run it and obtain the result as specified here - http://support.hyperic.com/display/hypcomm/Executing+Custom+Shell+Scripts+with+Hyperic+HQ
However, even though running my script form a command line with the exact command line path and arguments as given to Hyperic does in fact return a numeric result (decimal), Hyperic constantly says "no metric data available" for the Utilization / Result metric. It is running the command, because the return code is 0 (availability 100%), and the execution time looks correct. I have even written a new dummy script, which is just a bash script, and all it does is echo a number to STDOUT. Hyperic still refuses to display it as a result.
Reading the full documentation on the Script Service - http://support.hyperic.com/display/DOC/Script+Plugin - the example for obtaining a result value from the output contains a key / value pair separated with a colon. I don't know if this is enforced, or if Hyperic is actually supposed to just look for the first number it sees, but even when I output "Result: 4", Hyperic still doesn't see it. I am checking by using the Metric Data panel in the script service that I am looking at, and by turning on all indicators including those that do not have data (the Result Value has no data).
I don't really want to go the whole hog with and XML specification file as there is only 1 value output by the script and I'm not interested in other values at this point but I don't really understand why this simple script isn't working. I've simplified the example about as much as possible, so I'm hoping someone on here can point out what I'm missing.
