Calendar and Time Zone
You need to associate a time zone with a group to enable aggregation. A time zone determines the date stamp
for data. It is attached to a group and is associated with the resources and resource groups below it.
Calendars define non-operational periods called planned outages. When associated with groups, a calendar
controls when data for those groups are to be processed.
For more information, see the Netcool/Proviso DataMart Configuration Guide and the Netcool/Proviso Command Line
Interface Guide.
Threshold Detection
A threshold is a value that is compared against metrics to determine if the metrics exceed or drop below a specific
limit. Using thresholds as the measure against which data is evaluated lets you report on only those resources with
pertinent data.
The following are examples of thresholds:
• Burst threshold –“removes” the natural network bursts by evaluating how many times in a row the
violations occurred over a certain period of time.
• Period threshold – involves the concept of duration for which the threshold is violated. This duration is
accumulated until the end of the SLA period.
In addition, a threshold can indicate two different levels of meaning, warning and critical. You can deploy
thresholds per metric (for example the same threshold for all resources for a specific metric) or per resource.
For more information, see the Netcool/Proviso DataMart Configuration Guide and the Netcool/Proviso Command Line
Interface Guide.
Properties
Properties are the attributes or characteristics of an element or sub-element that defines its state, appearance, or
value.
The CME uses numeric properties in calculations with raw data or other complex metrics. The CME determines
what properties are required and loads them from the database at startup.
The properties are kept in CME memory. When a property value changes in the database, the CME obtains the
new value on the next load from the database.
Properties are installed by Netcool/Proviso Application Packs. You can also define new properties.

Operation Guide.
