1540.0. "DECmcc V1.2 Graphing utility questions" by TENERE::HAYES (A European Telecomet ...) Tue Sep 24 1991 09:08

	

	Hello,
	


I have some questions about the DECmcc V1.2 real time graphing utility.

It is said that unsignedX, integerX, CounterX, 
LcounterX, Bolean and real data types is supported.

My question relates to this example :

      TYPE RoutingCost = 58 RECORD 
        LocalCall    = 1 : Unsigned8;
        ExternalCall = 2 : Unsigned8;
        X25Call      = 3 : Unsigned8;
        END ;

Let's imagine an object called Routing Path. A status 
attribute (Cost) is defined as being of data type 
RoutingCost.

1) - Will the generic real time graphing utility be able to 
     graph the LocalCall, ExternalCall and X25Call 
     attributes ?

2) - If no, why not, will it ever be supported?

The reason for using Record data type, is that it gives 
a better user representation by sub-grouping 
attributes. 

                   Best regards

1540.1	Graphs support simple data types	TOOK::A_MOORE		`Tue Sep 24 1991 10:13`	10
	The real time graph supports simple datatypes. It does not support constucted data types. The why is: it takes more engineering time to do more complicated datatypes. We have to justify bells and whistles by defining user benefit or competitive advantage. Feel free to give examples of customer benefit of this feature for future versions. Al Moore

	This was directly extracted from a requirement of my preferred customer, which is not only a customer but also an SVP partner, and not only an SVP partner, but the largest european SVP partner. Guess who... Thanks for your quick answer Best Regards Catherine

Cathrine, please note that LocalCall, ExternalCall, and X25Call are NOT attributes based upon the definition you supplied. Instead they are portions of an attribute value. As stated by Al we will be able to graph attribute of primitive types (numerics). I understand the subfield idea but by doing such they have created a complex attribute, and not the three attributes that they meant to return.
1540.4	You have three attributes, not one record	BLUMON::SYLOR	Architect = Buzzword Generator	`Thu Oct 24 1991 09:57`	5
	This is a great example of why attributes of type record cause difficulties, but defining each field of the record as a separate attribute would work far better. I doubt very much that there is any reason why the 3 fields must appear as one attribute, they are almost always treated as separate values.
