Our Azure Elasticsearch instance has a hard disk of 60 Gb.
On our dev/acc environments, the hard disk took more than 55 Gb of space.
Which resulted into a disk usage exceeded flood-stage-watermark, Kibana was not available and search didn't work.

examples of monitoring indices:
How can we deleting monitoring logs automatically or modify some settings when they take too many place on the hard disk?
