RackPlannerPlugin

The RackPlannerPlugin handles the tag %RACKPLANNER% and renders a rack overview (HTML table) with devices (computer, router, switches, ...).

Syntax Rules

Devices are defined within a TWiki table. Following columns are supported:

Device	Rack	Starting Unit	Form Factor	Connected to:	Owner	Color/Image	Notes
device name(s) (separated by ' / ' or ' # ')	rack name	a starting unit (a number between 1 and units)	a form factor (units, e.g. 4U, 2, 1U, ...)	device(s) is/are connected to ... (comma separated list of other devices, ports ...); every 'connected to' item is displayed as a icon (see connectedtoicon, e.g. ) with the text as tooltip; if you use links the icons are also links;	the device owner(s) is/are displayed as tooltip of the device name	colors or a background image (a URL or shortcut, e.g. @sun - see attachments) for the table data cell	notes are displayed as a icon (notesicon e.g. ) with the note as tooltip; if you use a link the icon is also a link
must	must	must	must	optional	optional	optional	optional
Examples
Server1	RackS21	10	2U	port31	server admins	blue,white	not in use
Patchfield1 / Switch2	RackS21	40	1U	switch3 / router4	network admins / network admins	blue,white / green,white	3 ports free / 8 ports free
SunServer2	RackS21	15	4U	port12	sun server admins	blue,white,!@sun

You can use following %EDITTABLE% tag (EditTablePlugin must be installed) to simplify some things ( it must be one line):

%EDITTABLE{format="|text,10,|text,10,|text,5,1|select,1,1U,2U,3U,4U,5U,6U,7U,8U,9U,10U|text,20,|text,20,|text,10,|textarea,3x20|" 
header="|*Device*|*Rack*|*Starting Unit*|*Form Factor*|*Connected to:*|*Owner*|*Color/Image*|*Notes*|"}%

This %EDITTABLE% tag is an example. Feel free to modify the attributes (format and header). Hint: Put a %TABLE{initsort="3" initdirection="down"}% tag before the %EDITTABLE% tag to sort the table like the rack (modify initdirection to "up" if your first unit is at the top of the rack (dir="topdown")).

Notes:

• The device order in the table is not relevant (except there's a conflict) but the column order is relevant (because the table header will be ignored).
• If more than one device uses the same unit the conflict will be displayed with a icon (see conflicticon attribute, e.g. ). The tooltip of the icon contains the device names.
• If you have more than one device in the same unit you have to put them into a single table row and separate device names, 'connected to', owner, colors, notes with a ' / ' or a ' # ' (a whitespace before and after the separator is required).

Attributes

Usage: %RACKPLANNER{attribute1="value" attribute2="value" ... }%
Example: %RACKPLANNER{racks="rack1, rack2"}%

Attribute	Description	Example/Default
Behavior:
autotopic	set it on and every rack name is automatically used as source topic for the device definition (racks attribute is required and the value is attached to the topic attribute value); useful if you define your racks and devices on topics with the same names as the racks	autotopic="off"
dir	sets the direction of the units: topdown - unit 1 is at the top of the rack; bottomup - unit 1 is at the bottom of the rack; leftright - units are shown horizontal with unit 1 at the left; rightleft - units are shown horizontal with unit 1 at the right	dir="bottomup"
clicktooltip	if enabled JavaScript tooltips are only shown with a mouse click to the table cell instead of 'mouse over' (related: enablejstooltips, clicktooltiptext)	clicktooltip="off"
enablejstooltips	enables/disables JavaScript tooltips	enablejstooltips="1"
racks	a comma separated list of rack names to show; if omitted all racks found on topics (see topic attribute) are shown	racks="rack1,rack2"
steps	unit steps to display (useful if you use only every steps unit of a rack)	steps="1"
topic	a comma separated list of source topics	topic="%TOPIC%"
units	units to show	units="46"
Icons:
conflicticon	if a conflict exists this icon will be displayed	conflicticon="%S%"
connectedtoicon	if a 'connected to' entry exists this icon will be displayed with the entry as tooltip	connectedtoicon="%M%"

Notes:

• You can use TextFormattingRules for some attribute values: conflicticon, connectedtoicon, emptytext, name, notesicon
• Every attribute of %RACKPLANNER% can also be used as plugin setting. You only have to use capital letters.

Example
