Server Node Name

I was trying to get some control over the Server node name in the web control panel.

Right now, it seems to pick up the value in xx/couchdir/var/lib/couchbase/ip_start start file.

/couch/bin/couchbase-cli server-info -u Administrator -p password -c localhost:8091 returns the value in “hostname”

How can I set the server node name to something meaningful like: LondonNode03 (
instead of just ip address:
