Version 1

    In this release, we're thrilled to be adding flow support for for Meraki routers, and introducing completely new interfaces for navigating flow source and CBQoS enabled interfaces at scale. Also in this release - we've spent some significant effort to make substantive performance improvements - both in presentation, and in the ingestion and processing of flow records. We're also rounding out our Azure deployment story with comprehensive support for Azure managed instances.

     

    Meraki Flow Support

    Meraki MX and Z series routers export NetFlow v9 flow records. The implementation has varied over the last several generations of Meraki firmware, as vendors have worked to present the correct flow volumes and interfaces for traffic conversations. With this release, SolarWinds has worked with Meraki to implement support for these devices that accurately represents packet and byte counts, and associates the traffic conversations with the correct interfaces.

     

    The NTA product can adapt it's behavior to different Meraki firmware revisions to ensure we're providing accurate and granular data. For firmware revisions less than 15.14, we'll provide a mapping of the interfaces which is not available through SNMP, and we'll correct the byte counts for revision 14.7 and later.

     

    Getting the traffic by interface correct is important for our bandwidth hogs investigation. Our most common workflow is still the investigation of high-utilization interfaces to determine the primary traffic drivers.

    Meraki devices are integrated just the same as other sources of flow data, but are recognized and processed internally to ensure what we're presenting is accurate.

     

     

    Class-Based Quality of Service Interfaces

    New in this release, we've created a dedicated page for viewing and managing the collection of data from CBQoS enabled interfaces.  Class-Based Quality of Service is a Cisco specific feature that maps policies to interfaces. In previous releases of NTA, you could see CBQoS information on the NTA interface details page. Collection was controlled from the NetFlow sources page, which displayed both NetFlow and CBQoS controls for interfaces. In this release we've separated those functions, and provided dedicated pages for each:

     

    The CBQoS Polling Management page consolidates all CBQoS enabled interfaces into a single list, and offers sorting, filtering, and searching for the entire list. Interfaces are listed in a paginated list, with links to the NTA interface details or node details pages.

     

    The Flow Sources page is now exclusively dedicated to sources of all types of flow data, and has been similarly updated to provide for sorting, filtering, and searching. From this page, you can also manually override sampling parameters for sampled flow sources.

     

     

    The 2019.4 release includes common platform features like support for managed Azure SQL instances, expanded Orion Maps functionality, and platform-wide improvements in web performance.
