Hi Florian,

I found that the patch was not included in 4.10.1 release. Can you please let me know if this patch is going to make it to 4.10.x branch eventually?

Thank you in advance,

Thank you for your comments. I had submitted the patch already (email attached again). 

Is there any estimate when this code will be integrated in the "official" 4.10.x release? Is there anything else I can do to expedite the adoption of the code?

Thanks a lot

if you're using RRDtool, the number will be aggregated eventually.
Your best bet is to multiply the value by the time difference between two samples, which should result in roughly the number of lines matched in the displayed time period.

Reading those graphs is not trivial though, since the number in the graph will increase with the timespan being displayed as a result of more and more events being shown in the graph.

Personally I think what you're trying to achieve is best done with a COUNTER or DERIVE data source, but if should send a patch for a "GaugeInc" type I don't have any general objections ;)
