Highlights

An overview of the most impactful changes in this release.

Memory management improvements

This release brings significant improvements in the memory management by the operating system. These improvements are beneficial to all sensor types (physical and virtual), with the highest possible impact being observed in sensors with low memory allocation.

Centralized management of custom fields

In line with the needs of Enterprise deployments, the ability to manage device custom fields has been added. Now, custom field additions, deletions and modifications by Central Management Console (CMC) and Vantage users will be propagated down to all connected sensors. CMC and Vantage users may leverage these fields as a way to drive consistency across large organizations while retaining full control over the custom fields they create. Additionally, to avoid conflicts, when custom fields created at the CMC or Vantage match with existing sensor-level (local) custom fields, there is no override, the existing local custom field is assumed to have been “adopted” by the centralized users for Enterprise-wide use and the values stored in these fields are preserved. Conversely, should these custom fields be deleted by CMC or Vantage users, they will continue existing locally, because they proceeded the CMC or Vantage custom field creation.

Arc deployments using Microsoft Software Installer (.msi)

The support for Arc Microsoft Software Installer (MSI) installer has been extended to the automatic Arc deployment (in Windows PCs), resulting in Arc forming part of the list of installed applications accessible through the Control Panel, and thus allowing its management from the Control Panel. This MSI also includes all Arc software dependencies.

AWS deployment remarks

If your organization uses Amazon Web Services (AWS) to host applications, or the data for the assets that you want to monitor you can deploy your sensors in AWS. Before you can deploy with AWS, you must open a support case in the Nozomi Networks Support Portal to request access to the CMC Amazon Machine Image (AMI). For this, you will need to know the: To find your AWS ID, refer to Amazon's documentation on AWS identifiers. Upon receipt, we will grant access to the CMC AMI. Amazon EC2 T3 instance types are recommended.
