Dashboard reference

Use this reference to understand the Flow or entity metrics that are displayed on each dashboard, and other properties of the dashboard. The aggregations that are used on the NetFlow dashboards are also specified as applicable.

The following types of metrics are stored in Network Performance Insight® database:
  • Flow metrics

    The raw metrics from Flow records are aggregated and stored FLOW_METRIC schema tables.

  • Entity metrics

    The raw metrics that are discovered and polled from Tivoli® Network Manager are aggregated and stored in ENTITY_METRIC schema tables.

These individual metrics and a combination of the metrics are displayed in various dashboards and widgets. The data is queried and retrieved from the database with the help of REST APIs.

REST (REpresentational State Transfer) APIs rely on a stateless, client/server, cacheable communications protocol. REST applications use HTTP requests to post data (create and update), read data (such as running queries), and delete data. REST is a lightweight alternative to mechanisms like RPC (Remote Procedure Calls) and Web Services (such as SOAP and WSDL). Much like Web Services, a REST service is:
  • Platform-independent
  • Language-independent
  • Standards-based (runs on top of HTTP)
  • Able to be used in the presence of firewalls.
