Part III: Application Assurance
Overview
Purpose
This part describes the NSP Analytics reports in the Application Assurance category.
Data sources for reports
Application Assurance reports are based on application assurance (AA) information retrieved from file-based accounting records (AA accounting and/or ISA Performance) or from AA Cflowd records (IPFIX records augmented with application-level information). Unlike accounting-based data, AA Cflowd records are generated based on a sampling rate configured between 1:1 (no sampling – all flows are sampled and a record is created for each flow) to 1:N (where only one of N flows are sampled and one record created).
Sampling is a cost-effective method of collecting AA data for analysis – fewer resources are required to generate, collect, store and analyze the data. Reports that depend on AA sampled data are identified in this guide with “NSP Flow Collector required – Yes”. When the sampling rate is greater than 1:1 (for example, 1:10, 1:1000), the reports present data useful for approximations, comparisons (for example, Do I have proportionately more Netflix or Youtube traffic?), and identification of trends in subscriber activity, applications in use, volume of data consumed, and so on.
When report content must be representative of actual network and subscriber activity, then you must use only reports, ad hoc reports, or dashboards based on one of the following data sources:
Note: AA Cflowd Analytics reports may fail to generate or may contain invalid data if the configuration of 7750 SR is modified via dynamic templates to exclude required fields.
Global policies
Application and application groups must be enabled with global policies, not local policies. When local policies are used, applications and application groups are not populated properly in report prompts, resulting in the inability to select specific applications or application groups correctly at report run time.
