Description

Currently, we can view the node's bootstrap state in the following ways:

• via the nodetool cli tool, e.g. by running the "resume" command;
• querying the bootstrapped column of the system_veis.local virtual table;

In addition, we can also expose the status and state of the node's bootstrap via JMX. This is used by third-party tools that rely entirely on the JMX API and don't have access to the CQL interface. The operator will be able to get all the information they need from the dashboards without having to use CLIs.
