Make cluster nodes identifiable from the GUI¶
When running one or more clusters of GeoServer installations it is useful to identify which cluster (and eventually which node of the cluster) one is working against by just glancing at the web administration UI.
This is possible by setting one variable, GEOSERVER_NODE_OPTS
, with one of the supported
mechanisms:
as a system variable
as an environment variable
as a servlet context parameter
GEOSERVER_NODE_OPTS
is a semicolon separated list of key/value pairs and it can contain the following keys:
id
: the string identifying the node, which in turn can be a static string, or include the following substitution tokens
$host_ip
: the IP address of the node
$host_name
: the hostname of the node
$host_short_name
: the hostname truncated to not include the domain (foo.local
becomesfoo
)
$host_compact_name
: the hostname with all domain parts shortened to their first character (foo.local
becomesfoo.l
)
color
: the label color, as a CSS color
background
: the background color, as a CSS color
Here are some examples:
