If the problem is viewing, why not solve it in "rrdtool graph" ?


In other words:  get the two data sources, select the 2nd one if
the 1st one has unknown data.

Perhaps slightly better:


which will also catch the case where a switchover occurs and thus both
CDPs have known data.

I ask you to respect any "Reply-To" and "Mail-Follow-Up" headers.  If
you reply to me off-list, you'd better tell me you're doing so.  If
you don't, and if I reply to the list, that's your problem, not mine.
