Today if an Elasticsearch node reaches a disk watermark then it will repeatedly emit logging about it, which implies that some action needs to be taken by the administrator. This is misleading. Elasticsearch strives to keep nodes under the high watermark, but it is normal to have a few nodes occasionally exceed this level. Nodes may be over the low watermark for an extended period without any ill effects. This commit enhances the logging emitted by the `DiskThresholdMonitor` to be less misleading. The expected case of hitting the high watermark and immediately relocating one or more shards that to bring the node back under the watermark again is reduced in severity to `INFO`. Additionally, `INFO` messages are not emitted repeatedly. Fixes #48038 |
