Fix ElasticsearchTimeoutException
in ELK Stack
✅ Solution
ElasticsearchTimeoutException usually indicates that an operation, like taking a snapshot or cluster recovery, took longer than the configured timeout. To fix it, increase the relevant Elasticsearch timeout settings, such as `cluster.routing.allocation.disk.watermark.low` or `indices.recovery.max_bytes_per_sec`, in the `elasticsearch.yml` file, and ensure the cluster has sufficient resources by monitoring CPU, memory, and disk I/O. After modifying the configuration, restart the Elasticsearch nodes for the changes to take effect.
