NNMi and NA 10.21 Release – Expanding visualizations and enhancing automation efficiency!


In the 10.21 release of Hewlett Packard Enterprise Network Node Manager (NNMi) and Network Automation (NA), we added key features requested by customers and enhanced the efficiency and scalability of the core functions of both products.


Key additions in this release include:

  • VLAN Visualization
  • SNMP Proxy
  • Improved scalability for performance metrics
  • Enhanced HTML-5 for Device and Device Group selection
  • Removal of 9-core limit
  • Introduction of ‘Change Plans’ to improve automation efficiency


Network Node Manager I (NNMi)


VLANs interesting.png

On the NNMi network monitoring side, this version allows visualization of VLANs, and it dynamically updates topology as relationships change.  This new capability shows you an end-to-end view and can be filtered and focused to see only the VLANs you are interested in. The graphic above shows how you can ‘grey’ out the background information and just focus on the VLAN you are interested in.

Based on feedback from our MSP customers, we’ve rolled out our support for SNMP Proxy.  This capability lowers TCO for onboarding new customers:

  • Provides an additional tier for scaling discovery, polling and trap reception
  • Lowers the cost of maintaining customers in shared environments using fewer Regional Managers
  • Simplifies the onboarding of new customers

The graphic below shows an example of how this might be manager.png


To address the continued ask for performance in our Performance for Metrics iSPI, we’ve given you another option in the deployment matrix.  This version allows you to break up the database for NPS into multiple DB servers. This capability allows for the assigning of role-based DBs, like a read DB and a write DB, for example.  We’ve also allowed the ability to configure NPS at the GNM level without Regional-level deployment for ‘single pane of glass’ reporting across your entire infrastructure. 

Network Automation (NA)

 On the Network Automation side, more Flash was replaced with HTML5-based support, so you will see some slight changes in the UI.  One example of these changes is the Device and Device Group selection windows now looks like this.

 It’s a small change, but it really helps prevent or get rid of those annoying warning messages from Flash not being secure on the latest browsers.

The ‘Take Snapshot’ function was reworked extensively in this version to significantly reduce the bandwidth consumption for configuration changes. 

Here are the updates:

  • NA Core computes checksum/has for device configurations
  • SHA-512 is used to generate the checksum calculation

 When a change is detected or a snapshot is executed, the new checksum is compared to the stored checksum—instead of comparing the entire configuration.  Please install the September 2016 or later NA Driver pack to utilize these changes.

Another performance improvement is the removal of the 9 core restriction for NA.  Now more than 9 cores can now be configured with the newly developed HS Scripts (addServer.sql) for both Oracle and MSSQL databases.  This allows you to scale up your deployment for additional performance or to match the growing scope of your network.

The most interesting improvement in this 10.21 version of NA is the addition of our ‘Change Plan’ function.  Now you can validate the devices that are included from your inventory before you execute a change.  If no devices return a valid selection, then the change isn’t applied. It truly is as easy as it sounds!

In the figure below, you can see that a few options are available to establish your criteria.  Diagnostics, Device Attributes and Device Groups can all be used to focus in on just the devices you want to apply the change to.

Boolean expressions can be used to ensure the right combination of criteria are met and your change script can be chosen from your existing Command Script library.  These changes help ensure your Command Scripts are applied only to the devices you want updated and improve the efficiency of your automation.


We know these changes address some of the requests you had and look forward to your feedback on this new version.
