My cluster get data from metricbeat and save daily elasticsearch indexes. I'm intresting in best way to convert daily to monthly indexes. The goal is to decreas index storage size and show monthly view of performance.
I know that to easy way to create monthly indexes it to use reindex but I'm didn't found some example for process some fields before create monthly index. (to example: daily average for system.cpu.idle.pct, system.cpu.system.pct etc. fields). May it have another way using curator?
