I send data every day on one index, and I would like to delete all the data older than 15 minutes. I have set up the following ILM:
I notice that after 15 minutes nothing happens, then after about 25-30 minutes all past data is deleted except the last 5 minutes :
Why is the system not able to keep the last 15 minutes at all times with this configuration?
Thanks in advance for your help.
