Welcome to version 4.16 of our NetEye v4 Unified Monitoring Solution.
A difficult and tough year for everyone has gone, leaving us with uncertainty, some thoughts, and lots of hope for the new year.
NetEye welcomes the new year and its new release with a snow-covered view of the Alpe di Siusi/Seiseralm, for a glimpse of serenity and peace in these grueling days.
NetEye now supports out of the box an additional Voting Only Node, which acts as a tie-breaker in two-node (or any even number of nodes) cluster installations to avoid split brains, that can lead to data or service inconsistencies. For more info about the NetEye 4 Voting Only node you can read this article.
Furthermore, NGINX Elasticsearch load-balancing configuration is now aware of the presence of a voting-only node in the NetEye cluster.
In this release, we extended the NetEye automated upgrade procedure to support voting-only NetEye cluster nodes, thus reducing the manual steps required to upgrade this kind of node.
neteye upgrade command now installs the RPMs of the new NetEye version also on voting-only nodes, and the NetEye agent and the NetEye health checks have been both extended to support voting-only nodes.
Detailed information is provided in the specific upgrade documentation from 4.15 to 4.16 in the User Guide > Upgrading and Updating [verify this location when releasing].
We updated the NetEye base OS packages from CentOS minor version 7.8.2003 to 7.9.2009, which are now available for all NetEye 4 Versions.
Further information can be found at the following link: https://wiki.centos.org/Manuals/ReleaseNotes/CentOS7.2009
Icinga2 packages that allow using all the functionalities of NetEye 4 (such as Command Orchestrator and Shutdown Manager) are now available not only in form of RPM but also for different operating systems, like Debian derivatives or Windows. These packages are available in the NetEye repositories.
More information on the installation of the packages can be found in the User Guide > Initial Configuration > Icinga2 packages.
We updated Icingaweb to version 2-2.8.2_neteye1.81.0-1. We have modified the default filter of event overview to ‘timestamp>=-7 days×tamp<=now’. This modification will filter the events list in the last 7 days.
We updated telegraf version 1.14.1 to 1.16.3. This update contains the most recent Telegraf Input, Output, Processor and Aggregator plugins as well the latest bug fixes and the new custom programmatic metric processing language Starlark (Full Changelog Here).
ITOA based on Grafana is now shipped with a completely new theme based on Carbon Design System. The default ITOA theme for NetEye 4.16 will be the dark one. For an improved user experience, the ITOA module is now opening in a new tab, leading the user directly to a “wide screen” mode.
We upgrade Elastic Stack from 7.9.1 to 7.10.1, which brings:
Refer to the Elastic Stack Release notes for additional information:
The Snapshot and Restore functionalities provided by Elasticsearch and Kibana are the best options to manage SIEM backup. As a consequence the Elasticsearch backup scripts (User Guide > System Configuration > Elasticsearch backup) provided in NetEye are deprecated, and they will be removed in the next release.
