An instance name is used by the Greenplum Command Center as
a way to uniquely identify a Greenplum Database that has the monitoring
components installed and configured. This name is also used to control
specific instances of the Greenplum Command Center web UI. Instance names
can contain letters, digits and underscores and are not case sensitive.
Please enter a new instance name:
> gpmon
The web component of the Greenplum Command Center can connect to a
monitor database on a remote Greenplum Database.
Is the master host for the Greenplum Database remote? Yy|Nn (default=N):
> n
The display name is shown in the web interface and does not need to be
a hostname.
What would you like to use for the display name for this instance:
> linux1024
What port does the Greenplum Database use? (default=5432):
>
Creating instance schema in GPDB. Please wait ...
The display name is shown in the web interface and does not need to be
a hostname.
Would you like to install workload manager? Yy|Nn (default=N):

Skipping installation of workload manager.
The Greenplum Command Center runs a small web server for the UI and web API.
This web server by default runs on port 28080, but you may specify any available port.

Done writing web UI clustrs configuration to /usr/local/greenplum-cc-web/./instances/gpmon/conf/clusters.conf
Greenplum Command Center UI configuration is now complete. If
at a later date you want to change certain parameters, you can
either re-run 'gpcmdr --setup' or edit the configuration file
located at /usr/local/greenplum-cc-web/./instances/gpmon/conf/gpperfmonui.conf.
