[Xymon] Another weirdness - RRD info has gaps

[Tim McCloskey]

I've seen this before but I don't remember the exact cause, I just remember that working on rrd stuff tended to add gray hair.  Do both of these graphs have essentially the same rrd configs?  If the foo.rrd files do not contain the detail for the tests I would truncate foo.rrd, and recheck my [foo] graph stanza. (rather, save a copy off foo.rrd first)

accidentally snipped off the tail interval there, but it's still matching:
