TNPFA 4.1.1 Installation and User Guide - e IBM Tivoli Composite ...

Figure 4-4 shows how aspects are defined in the user interface. The default collection type for
collecting usage variation information is Time Array. This type of aspect represents traffic in sent and
received directions separately. Sent traffic is above the x-axis. Received traffic is below the x-axis. A
Unidirectional Time Array does not differentiate between sent and received traffic – both are added
above the x-axis. A Counter aspect records separate totals for sent and received data for the current
and last time period. The only graphical representation for the data in counter aspects is pie charts.
Figure 4-4 Site Configuration > Aspects
A defined aspect has to be enabled for collection before the database maintains information for the
aspect. To enable each aspect for collection with respect to time periods and units, click Configuration
> Site configuration > Collection. The possible time periods are hour, day, week, month, quarter,
and year. The possible units are octets, packets, and flows (see Figure 4-5). In addition, the system
provides a means to filter and rewrite the incoming flow information records during the collection
process (see Figure 4-6).
Note: When you configure aspect collection with more periods and units enabled, the memory
consumption increases.
