We are trying to implement single node cluster of Elasticsearch per installation of our application. Our application is on-prem. I was looking at the indexing data location parameters in the Elastic documentation. I came to know there are disk-based shard allocator settings with following parameters,
I would need to know whether by default Elasticsearch sets the disk threshold as Enabled?
I don’t see the use case of keeping it enable by default in a single node cluster where we will be having multiple disks on a single node/server. We will write our own disk alerts to monitor the threshold.
It would be good if anyone can explain the low and high alert meaning with some simple examples?
