[rrd-users] Re: large values equal NaN?

[John Barber]

Glad I could help.

I was just speaking from experience.  I once created an rrd that I was
planing on storing data as a percentage in, so I set the max to 100 then
later changed my mind and couldn't figure out why it wasn't recording
any values.

John,

You the man!  That was simple enough!   rrd info showed the wrond max
value and rrd tune fixed it to a larger number.  Sheesh -
thanks...just
needed another set of eyes on that problem!!!!  Thanks tons!
