Descriptions of Provided Host Tags

Each broker sets a few well-known system-defined host tags when starting up, in part inferred from the operating system. These are considered transient (that is, not durable) host tags because the value of the tag is determined on the broker at startup. These host tags are not modifiable by the user. Here is an example using NuoDB Manager to list the system-defined host tags for all hosts in the domain:
