Have upgraded my test host in the hope 2.10.5 fixes
the still outstanding issues with Thresholds.
It seems its still not functioning properly.

On 2.9.29 this config still runs perfectly and
triggers correctly, but on 2.10.5 it produces
either of 2 errors.

Use of uninitialized value in system at /usr/local/mrtg/mrtg line 1609.

The output of the target line is always in the format.


If there is no response we get a "0" and triggers the Threshold.

Any help appreciated.
