We would like to detect when a shard fails, begins relocating off of a node, and finishes relocating. We do use the metrics that show the count of these active operations, but would like to additionally know the specific shard, index, and nodes involved.
I am aware that we can enable logging at a per-java-package level, but I don't know which logs might have this information. Are there any specific logs that capture this information?
We're using ES 5.6 temporarily, and will be on 7.9 soon.
