To access flow information and functionality
Introduction:
Entuity Integrated Flow Analyzer integrates flow-based performance data alongside Entuity's elemental performance data.
Note, with the correct license, you can have access to Integrated Flow Analyzer Premium, which provides increased functionality.
What can you identify with flow collection?
- network congestion
- applications consuming high bandwidth percentages
- destination of network traffic
Data can be collected and stored with a granularity of 5 minutes, and is retained for one month. Flow data is collected from its own local collector. Data is stored in a compressed form, but can also be stored in an uncompressed form by disabling de-ephemeralization.
On a high specification dedicated flow collector, Entuity can support 100,000 flows per second.
Who has access to flow data?
Members of the Administrators user group have full access to flow collection and data functionality.
Members of other user groups can only access flow data with the Flow Inspection tool permissions, which are Flow Management, Flow Query Management, and Flow Viewing.
Flow Management (in Entuity v19.0 P03 and below, this was called 'Flow Inspection'):
- view flow data.
- start and stop flow collection.
- generate charts.
- access flow data when creating reports.
However, the 'Flow Inspection' tool permission does not enable the following for users:
- run the Flow Health report.
- assign flow collectors to master flow collectors. This is a function only available when running IFA Premium.
Flow Query Management (as of Entuity v23.0 P01):
- view flow data.
- load, view, and configure both personal and shared flow queries.
Flow Viewing:
- provides access to dashboards to view flow data.
- load, view, and configure personal flow queries.
- load and view shared flow queries.
To access flow information and functionality:
There are three ways you can access flow information:
- From the Flow Inventory page in Administration.
- From the Application Port Mappings page in Administration.
- From the Flow dashboard or a custom dashboard containing flow dashlets.
Flow data retention:
Flows generate a large amount of data, for which Entuity uses four levels of data rollup. By default, IFA retains:
- 5 minute samples for 2 hours
- hourly samples for 24 hours
- 6-hourly samples for 7 days
- daily samples for 35 days, although access to a maximum of 31 days is available through the UI
When you query data, Entuity uses the most appropriate data sample, for example, hourly data is accessible when the requested time period is less than one day.
Users with the Flow Inspection permission have access to all collected flow data, including data from interfaces to which they otherwise do not have access in Entuity.
