If you decide in the task before this one, to change the SPECTRUM attributes for the model/table in your PDB,
now is the time to add variables that correspond to these metrics. See Cabletron Spectrum Appendix 6: Mapping
SPECTRUM Data Types to an IT Service Vision PDB in this document for information on adding new variables
to a table.
To add new variable(s) in the View Variables window, follow this path:
select variables -> close
then follow the information under [help] on each tab.
To return to the list of variables, select OK.
e. Adjust the Kept status of the variables, if necessary.
Look through the decisions that you made in the prerequisites to this task for the variables for which you now
want to keep data. For that set of variables, find the ones whose Kept status is currently No. To change the Kept
status for all these at the same time, follow this path from the list of variables:
select list of variables to change from No to Yes -> right mouse click -> Properties ->
Modify the kept in PDB status to
Yes
Data will be kept at detail level for these variables.
Look through your list for the variables for which you no longer want to collect data. For that set of variables,
find the ones whose Kept status is currently Yes. To change the Kept status for all these at the same time, follow
this path from the list of variables:
select all variables to change from
Yes to N o -> right mouse click -> Properties -> Modify
the
Kept in PDB
status to
No
Data will not be read and thus not kept at detail level for these variables. As a consequence, data will also not be
available at reduction levels for these variables.
f. Adjust the calculation status of the statistics on the variables whose Kept status is Yes
,
if you require
values different from the default settings.
One of the attributes of a variable is its interpretation type, such as INT, C2RATE, STRING, TIME, and so on.
By default, IT Service Vision calculates the same statistics for all variables of the same interpretation type. For a
table of the default statistics that correspond to each interpretation type, see Shared Appendix 6: Characteristics
of Variables.
select the variable -> click right mouse button -> Properties -> Statistics
If you want to change which statistics are set for a variable, IT Service Vision displays a grid of statistic vs. level.
Highlighted statistics are calculated at the indicated level.
For all the variables, if you want to see which statistics are selected it is often easier to look at the complete table
definition (see the Prerequisites in this task). Note that in a variable definition, the statistics are listed by level.
