What Types of Data Reports Are Available?
10.5.2 Viewing Utilization Data
The Utilization Data Report verifies all ports, and connections. Utilization is based on percentage of
total bits received in seconds and total bits transmitted in seconds. You specify the parameters listed that
crosses the threshold value.
These tasks are used to configure Utilization Data Reports:
• 10.5.2.1 Calculating the Percent Utilization for Top Utilization Reports
• 10.5.2.2 Generating a Utilization Data Report
• 10.5.2.3 Exporting the Utilization Data Report
• 10.5.2.4 Generating a Utilization Data Report for Connection Endpoints
For more information on the supported objects for each report type, see Table 10-4.
10.5.2.1 Calculating the Percent Utilization for Top Utilization Reports
For percent utilization, the data is aggregated over a time period specified in the report.
Table 10-5 lists the calculations for the ports, and connections.
Table 10-6 lists the method conversion that are used to convert to bps.
Table 10-5 Percent Utilization Calculations for Top Utilization Reports
Type Calculation
Ports
Percent bytes received from the network (number of packets or cells) received per
second or port speed) * 100
Percent bytes transmitted to the network (number of packets or cells) transmitted
per second or port speed) * 100
Percent utilization of the port = percent bytes received from the network +
percent bytes transmitted to the network
Table 10-6 Method Conversion for Endpoints
Endpoint Method Conversion
ATM Convert cells received to bps by using the conversion formula, for example, each cell
has a 48 B payload.
bps = (number cells received / (bucket interval * 60)) * 48 * 8
Voice and Data Convert packets to bits per second (each packet has 24 bytes)
bps = ((number packets received / (bucket interval * 60)) * 24 * 8
