Ben,
Below is the patch I created to display all metrics regardless of which hosts
might have different sets of metrics. It is essentially the same
modifications that Richard previously described (I had just chosen a different
variable name). However, it is a patch against 3.0.1 and not the latest
version, so I don't know if it will apply cleanly. Luckily, the patch is very
simple so there shouldn't be any problems getting it to work with the latest
version.
Hope that helps.
