We can see that rateup is exiting with an error but not see the error
message being produced by rateup (only the error being produced by mrtg,
which calls it)

You need to test rateup somehow.

Try running rateup from the command line to directly update one of your log
files (I forget the exact syntax required as I haven't touched rateup in
over 10 years); you might get some infor this way.


Possibly your .log files are corrupted, or have incorrect permissions or

The stderr/stdout shows the same thing that appears in the logs.

mrtg is not a shell script, its a perl script.  So, you dont call it with
'sh -x', you call it with 'perl'.  Otherwise you get error messages as the
shell interpreter gets confused by the perl code.

You can increase the logging in MRTG, but the error appears to be in the
rateup call rather than in MRTG.  You need to capture the stdout/stderr from
the mrtg call so that you see any error messages produced by rateup calls,
this might give more light on the reason for the rateup error exit.
