ERROR: unknown data source name 'toaster1_nyc'

[Guest]

i'm seeing these in my Apache error log, when trying to update some of my data sources. i have a feeling it is caused by some characters i use in the data source names? In particular, dot and dash.

Could someone confirm?
Sure, the DataSource page says "Name: The name used for RRA files, among other things; no spaces or strange characters.", but "strange" is pretty meaningless. Are the supplied strings checked for the "strange" characters and reject them?

First of all, that error is being caused by rrdtool. It is complaining that you are referencing to a data source name that it does not have a DEF for. Cacti will normally handle this for you, unless you are using a data source for a GPRINT and NOT the AREA/STACK/LINE.

You'll want to double check your graphs to make sure this is not the case. Future versions of cacti will not care as much where/how a data source is used on the graph.

The name itself looks completely valid.
