So what happpens when you specify this OID in the MRTG config file?  Do you
get an error from MRTG?  Are you sure MRTG receives "gauge:21"?

Could it perhaps be that MRTG didn't complain but also didn't produce the
desired result?  If so, you may have forgotten to set the gauge option?

I wrote you a script that might help.  It is a shell script, not perl.

Run this script and it should return
     quite some time
