This dialog box is for specifying the list of resource queries to be
sent to the node's MOM daemon. This query can be anything from a simple
expression involving only MOM query keywords (ex. loadave), or to
complex expressions made up of numerical constants, arithmetic/logical/bitwise
operators, and MOM keywords (ex. "(loadave/ncpus)*100)"). The valid operators
are: -,~,*,/,%,+,^,(,),<,>,|,&,=,!, <<, <=, >>, >=, ==, !=, &&, ||. Some
possible query keywords are given in the following, listing also the
architecture of the host (that is running MOM) where the keyword is valid:

A description of each keyword is given below:

sessions        - list of sessions in the system
pids            - list of pids in a session
nsessions       - number of sessions in the system
nusers          - number of users in the system
totmem          - total memory size
availmem        - available memory size
ncpus           - number of cpus
physmem         - physical memory size
idletime        - seconds of idle time
loadave         - current load average
swaprate        - swap activity in chars / sec
swapinrate      - swapin activity in chars / sec
swapoutrate     - swapout activity in chars / sec
swapused        - chars swapped out
swapavail       - chars available in swap area
swaptotal       - total chars in swap area
cpusysw         - percent cpu system wait

cpuuser         - percent cpu user
cpuidle         - percent cpu idle
cpuguest        - percent cpu guest

The result of the query (Query_Expr) will be displayed on the node's canvas
with an accompanying text label (Display_Info) and the output format
(Display_Type) can be in one of 2 ways: TEXT, SCALE. TEXT means that the
result will be displayed as is, while SCALE will show an actual scale
item/widget calibrated over 100. For the latter, be sure the result value of
your query is numeric  and that a value of 100 is considered "optimal".

So specify the query expression in the Query_Expr entry box, the accompanying
text label on the Display_Info entry box, and drag the mouse over the
Display_Type CHOICE entry box and click the left button to display the
choices: {TEXT, SCALE} for the output format of the result. Then click "add"
(or simply hit <return>) and watch as your input gets added to the Queries
listbox. For example, if you specified:

Query_Expr		Display_Info		Display_Type
---------		------------		-------------
loadave			Load Ave:		TEXT

then if the result of the query is "0.22", the  node's canvas will display:

Load Ave:	0.22

After putting in all the necessary parameters, then simply click the "ok" button
found at the bottom of the dialog box.
