My current config is set to rotate the active write index each day, this works as intended.
My current config is set to delete old indices, with a maximum number of 2 indices. However there are now 18 indices, and old ones aren’t being deleted. I have tried restarting GL and rotating and recalculating the indices.
Once I resolved this issue I went back to look at the retention strategy issues, but to my surprise the other indices were gone and there were only two as I expected.
