Ekaterina Dimitrova updated CASSANDRA-16378:
--------------------------------------------
Description:
Recent java-driver's
[com.datastax.oss.driver.api.core.session.SessionBuilder|https://docs.datastax.com/en/drivers/java/4.9/com/datastax/oss/driver/api/core/session/SessionBuilder.html]
respects properties
[ApplicationName|https://docs.datastax.com/en/drivers/java/4.9/com/datastax/oss/driver/api/core/session/SessionBuilder.html#withApplicationName-java.lang.String-]
and
[ApplicationVersion|https://docs.datastax.com/en/drivers/java/4.9/com/datastax/oss/driver/api/core/session/SessionBuilder.html#withApplicationVersion-java.lang.String-].
It would be helpful to expose this information via virtual table
{{system_views.clients}} and with {{{}nodetool clientstats{}}}.
+Additional information for newcomers:+
The drivers can send as part of the {{STARTUP MESSAGE}} the
{{APPLICATION_NAME}} and {{APPLICATION_VERSION}} options. To new volatile
fields {{applicationName}} and {{applicationVersion}} need to be added to
{{ClientState}} in a similar way to {{driverName}} and {{{}driverVersion{}}}.
The {{APPLICATION_NAME}} and {{APPLICATION_VERSION}} optionsneed to be
retrieved in {{StartupMessage#execute}} and passed to the {{{}ClientState{}}}.
The new {{application_name}} and {{application_version}} columns need to be
added to the {{system_views.clients}} represented by the {{ClientsTable}}
class. The data then need to be retrieved from the {{ClientState}} through
{{{}ConnectedClient{}}}.
Some unit tests similat to {{SettingsTableTest}} should be added.
