General Reporting Utilization Reports DDR Reports At the portal application selection page, in the upper right-had corner is a Preferences icon . Click this icon and you will be taken to a page that allows you to change your Mersoft portal preferences. Note:This is different than your ATM Reporting preferences. The Mersoft portal preferences allow you to change your password to the portal.
What other applications are available through the Mersoft portal? For Sprint customers, the following application are available:
How current is the ATM performance data? Unless otherwise arranged with Mersoft, all data is collected from Sprint on a 24-hour basis between the times of 8:00 PM CST and 6:00 AM CST. Sprint updates their data store every 2 hours and Mersoft does have the ability to retrieve information on a reoccurring 2 hour basis. For more information about this capability, please contact Mersoft.
How far back in time can I see reports? For the basic performance reports as provided by Sprint, you can see data going back 45 days. Mersoft offers additional storage available in the Professional and Enterprise packages.
What is the lowest interval of time for the data collected? Sprint provides Mersoft data that is collected on an hourly interval. The lowest granularity that can be reported is hourly.
Sprint does not currently offer reporting on all device types. Sprint's official statement regarding device type availability is show below: ATM performance information Currently includes data collected from the Marconi ASX4000 and Nortel Vector ATM edge switches. NEC switch related performance reporting information is targeted to be available in mid November, 2002. DDR statistics for ATM circuits which terminate to a Frame Relay, Internet or International gateway are currently not available.
How is port utilization calculated? Port utilization is calculated by taking the total number of bits transmitted and dividing that value by the total ATM bandwidth capacity for the physical port.
What is the difference between average utilization and maximum utilization? The average utilization is calculated by averaging all hourly utilization over a specified date range. The maximum utilization is the highest single interval utilization taken over the same specified date range.
How is VPC/VCC utilization calculated? For the basic reports provided by Sprint, the VPC or VCC utilization is calculated by taking the total number of bits transmitted and dividing that value by the SCR value. In the Professional and Enterprise packages, you have the option of calculating VPC/VCC utilization over SCR or PCR.
Why is average or maximum utilization on VPC/VCC greater than 100%? The VPC/VCC utilization is being calculated using SCR. If you are consistently running over SCR, the avg and max utilization will be over 100%. In the Professional and Enterprise packages, you have the option of calculating VPC/VCC utilization over SCR or PCR.
The Data Delivery Ratio (DDR) is calculated by taking the number of bits transmitted from the A-side virtual connection and dividing it by the number of bits received from the Z-side virtual connection. The same calculation is also done in reverse for the Z-A link. The two values are added together and then divided by 2.
Why are some values blank on my DDR report? A blank value on a DDR report is usually caused by one of the following issues: 1. One end of the connection terminates on a unsupported device and no data is being collected. 2. Both ends of the connection are reporting zero utiliation.
Can I use the DDR report as prove of a Sprint SLA violation? Sprint has provided the following information: This information is acceptable to Sprint as verification of POP-POP Availability and POP-POP DDR SLAs. |
