Here it says that "number_of_replicas": "0"
But look at the "Index patterns" from the picture above.
Template has: "ilm-history-5*"
But the index which was created: "ilm-history-3-000004"
So why ilm-history index was created with different name than its template..?
If there is no template for certain index, is the default value for number_of_replicas = 1 ? (if so, can I change this default?)
Nop.
As I said. I have single host cluster with 7.11.1 version.
I don’t have any template for “ilm-history-5*” also.
For some reason template is for “ilm-history-3*”
And index was created starting with “ilm-history-5..”
That's precisely the opposite of what you said in your original post: the index is called ilm-history-3-000004 but the template in the screenshot matches ilm-history-5*.
I don’t have any template for “ilm-history-3*” also.
For some reason template is for “ilm-history-5*”
And index was created starting with “ilm-history-3..”
I have checked all my 7.11.1 clusters.
All of these have the same behaviour - at midnight clusters all went to "yellow" state due to this "ilm-history-3" index.
E: "yellow" state followed for all the clusters where I had single host in cluster. But the issue still stands for multi node clusters also, since it is not using its designated index template.
