For a given installation, some variables can be set to customize the Viewer.

	Note
	If you want to change the value of certain variables, please contact the Favendo team, as they will have to change it in the backend.

Variable	Possible values	Default	Explanation
RA_SHOW_GEOJSON_LABEL=false	true/false	false	If set to true, the fixed zone labels in the middle of the zones will be shown at a certain zoom level. If set to false, the fixed zone labels won’t be displayed at all. In either case, you will see a floating zone label when you hover over the zones.
RA_SHOW_STATUS_TABLE	true/false	true	If set to true, the table will be activated and accessible through the “TO THE LIST” button.
RA_THROTTLE_INTERVAL	An integer in ms, for example 500	500 ms	The map update rate. This is the maximum rate at which the positions of the markers are updated on the map. Note that the update rate of the positions in the viewer depends not only on the environment variable, but also on the update rate of your tracking system. The lower of the two will be what you see in the viewer.
RA_USE_CLUSTERS	true/false	true	When set to true, markers on the map that are close to each other are grouped into a cluster.
RA_TABLE_HIDDEN_COLUMNS	Comma-separated strings	null	To hide specific table columns, specify a comma-separated list of column names.
RA_ASSET_EVENT_BTN_TEXT_KEY	Only two values are possible: “dematch” or “ping_tag”	null	Hover text label when the optional button at the end of the Viewer table is activated.
RA_ASSET_EVENT_BTN_ICON	Any icon from the MUI icon library. For example: “WbTwilight”	null	The icon of the option button at the end of the Viewer table if activated
RA_MATCH_KEY_FOR_PING_ASSET	Only one value is possible: “VIEWER_BUTTON1_CLICKED”	null	This is the matchkey Favendo’s event manager is listening to.
