Utilization reports information overview
General information
Utilization reports provide utilization or uptime information at the NE, port, SAP, service or customer level.
Limitations
Report limitations include:
-
Customer specific reports (Customer Utilization Summary and Customer Uptime) may not complete if they are run on customers with more than 100 000 services.
-
Changing the graph type of a report, for example, switching from a line chart to a bar chart, can take 30 or more seconds to complete.
-
Running customer level reports with output on one page may impact the time required to generate the report. In extreme cases, report generation may fail.
-
The 7705 SAR prior to Release 8.0 does not support the Complete Service Ingress Egress and Combined Network Ingress Egress Octets accounting policies. As a result, utilization reports that rely on these accounting policies will not show data for the 7705 SAR pre-Release 8.0.
-
The utilization graph in forecast reports does not stretch when the forecast in the graph is unselected.
Drill-down reports
All Utilization reports can be run from the main Utilization reports folder. Some reports can also be run as drill-downs by clicking on a data point in another report.
The following table shows the drill-downs available for Utilization reports. Each level of indentation indicates a drill down. For example, Port/LAG Details and Service Utilization Per Port reports are both drill-down reports from a Port Throughput Summary report.

Note: Using the Show Report On One Page option when creating reports as drill-downs may impact report rendering time. Nokia recommends disabling the Show Report On One Page option when creating reports.
Aggregation
Utilization reports are available without aggregation (RAW collection) or with user-selected aggregation granularity. RAW collection uses the periodic time from the statistics collection to calculate utilization for periods when statistics are available. Aggregated collection calculates utilization for the requested report duration, regardless of whether statistics data is available for the entire period. If a collection failure occurred during a report internal, the utilization reports collected using RAW and aggregated collection will not match.
