If you have an invalid rrd graph command inside snmp-graph.properties, it would be nice if instead of a big stacktrace exception you would get a shorter message of the problem.

For example, if you had a definition entry like:

DEF:inMax:{rrd1}:udpInDatagrams:MAX

It would be nice to see a message like:

Invalid definition: DEF:inMax:{rrd1}:udpInDatagrams:MAX

instead of a stack trace of:
