Is there any way to know how much data are we pushing to an Index monthly?

I wonder if there is any way to monitor how much data are we pushing to a specific index.
i can see some information on the monitoring section but i dont think i can pull off the information i am looking for from there.

any help is appreciated.

Thanks
Daniel

If Monitoring isn't showing what you want, what exactly do you want?

i would like to know how much data gets in a specific index by day or month.
i dont seem to find a way to query the monitoring.

We don't store that, just the index size.

You would need to install the mapper size plugin to get an accurate sizing. Or you can just take the index date range and then divide the size by that.

where could i find the range?
I looked into the index like this:

GET /ct_*/_stats but i dont see the range.
