[rrd-users] Help with RRD.... in over my head

'rsion of' looks like part of the string "Version of", which it would fail to convert to a float value of course.  It might be that you have a separate errorin your code that calls the rrdtool update and you are not passing a float value but are instead passing this string.  Since you have not provided the actual code or script you are running I can only guess...

I hear what you are saying.  I was entering in about 4000 data points spread out across 24 hrs  and getting these type of errors:
return_value = -1
' to float not complete: tail 'rsion of '0

I decreased the data count to 2 to see if I could isolate which value was causing that tail rsion error.  I will play around further with what you suggested but any ideas on the error noted above?

Thanks for all your time. I really appreciate it.
