Hi,
Everyday i am facing red health on Elasticsearch. Then i am chencking the indices under index management and i am seeing one or two red metricbeat indices. After i marked them and i deleted them the cluster health comes to green again.
The annoying thing is that i am facing it everyday.
I am sendig you the GET /_cluster/allocation/explain?pretty in order to help me if there is another way to solve my problem from not deleting the red indices everyday.
