Restrictions and limitations

To avoid compatibility issues, ensure your monitoring cluster and production cluster run on the same Elastic Stack version. Monitoring clusters that use 8.x do work with production clusters that use the latest release of 7.x, but this setup should only occur when upgrading clusters to the same version.
Monitoring across regions is not supported. If you need to move your existing monitoring to the same region, you can do a reindex or create a new deployment and select the snapshot from the old deployment.
The logs shipped to a monitoring cluster use an ILM managed data stream (elastic-cloud-logs-<version>). If you need to delete indices due to space, do not delete the current is_write_enabled: true index.
Traffic filters on monitoring deployments are supported on version 6.0 and later. Both the monitoring source and the target need to be on version 6.0 or later.
Log delivery is only supported on production deployments version 6.0 and later, and it requires a monitoring deployment version 6.5 and later.
Verbose logging in Kibana is only supported on production deployments version 7.6 and later.
When sending metrics to a dedicated monitoring deployment, the graph for IO Operations Rate(/s) is blank. This is due to the fact that this graph actually contains metrics from of all of the virtualized resources from the provider.
