Hello,

Here is a feature suggestion for Graphite.
Sometimes the client sends values, but sometimes nothing is sent.
It would be good to have a default value when nothing is sent, instead of "no data".

Here is an example: let's say I send the value 1 when my job starts, and 0 when it stops.
By using "keepLastValue", I can monitor in real time when my job is running and when it stopped.

Now, if my job failed before sending the value 0, Graphite will keep displaying the value 1 even if the job is not running anymore!

The defaultValueifNoData function I'm suggesting ccan fix this.

Thanks & regards.
