[rrd-users] How To Graph with Occasional NaN (OK)

[Patrick Best]

Hi everyone;

I have a data source that occasionally provides a NaN.

This is OK for us, it's expected about 20 times a day or so.

What we'd like to do is to eliminate "gaps" in the graph data, by using a technique like drawing a similar value as the last good poll.

Is there a way we can do this?

Is there a selector that can tell rrdgraph how to interpret NaN ?  Or would the mechanism be in the creation of the rrd?
