These release notes for NetEye 4.7 describe new features and improvements compared to version 4.6. The complete change log, which includes all fixed issues, can be generated on demand by following the instructions in the updated NetEye documentation (see the section “Starting your Upgrade” below).

New Features

SLM Module

A new Service Level Management (SLM) module is available for NetEye 4.7. It provides tools to associate Monitoring Objects with SLA target metrics, calculated over a specified Service Level Window for a specific customer in so called contracts.

These contracts associate a specific customer with a set of monitoring objects , and define the exact time frame to be observed (the Service Level Window), as well as the thresholds for the computed metrics, so that it is possible to verify the satisfaction of their contractual service level agreements.

The SLM module uses the existing Reporting module to create HTML and PDF reports for a specific customer, showing the metrics (currently Availability) and their satisfaction for the related monitoring objects. This module is available with an additional NetEye SLM subscription.

At present the SLM Module computes the availability expressed as a percentage for monitoring objects in the service level window. Future metrics like the number of outages, MTBSI, and MTRS are planned. The SLM documentation (User Guide > Service Level Management) describes both the details of the API and the graphical interface.

Log Manager
Beginning with this release, the Log Manager module will have a new configuration entry that supports the systematic deletion of outdated logs (from both rsyslog and Elasticsearch) according to a user-configurable retention policy. Expressed in days, the retention value defaults to one year (365 days) and will be applied to all hosts which do not have a different value configured on either the host itself or its host template.

At midnight after the 4.7 update has been applied, all rsyslog and Elasticsearch logs already stored in the system that are older than one year will be deleted. If you desire a longer retention period for your existing logs, you should change this value immediately after you update to version 4.7. You can find more details about retention in the updated user guide at User Guide > Log Manager > Retention Policy for Log Manager.

Technical Preview

Tornado
Tornado now has the capability to process incoming Email messages, and to interpolate Strings in Actions, such that more complex outputs like check results using perfdata are possible.

The new comparison operators greater than, greater than or equal to, less than, and less than or equal to for numerical data are also now available. All of these new features are described in detailed How Tos at User Guide > Tornado.

In addition, with this release we introduce a preview of our first Tornado frontend component, the Processing Tree Viewer. You can use this GUI panel as a check that your hand-written configuration rules were correctly read by Tornado.

Improvements

Lampo

Lampo monitoring integration has improved and Lampo now also has the ability to search for hostgroups and servicegroups in addition to hosts and services.

Standalone Updates to the User Guide

In addition to documentation for the issues listed above, the user guide has been updated to include the following new content:

  • User Guide > System Configuration > Host and Service Check Creation
  • User Guide > System Configuration > Recurring Jobs and Systemd

Deprecations

Log Manager

As noted above, after completing this update you must immediately change the new Log Manager default retention policy of 365 days if you do not wish for your rsyslog and Elasticsearch logs older than one year to be deleted.

Module and OS Updates

The following software has been updated:

  • Updated Safed Agent v1.10.1 UX
    – The Safed agent for AIX Version 7.1 now supports TLS 1.3 based on wolfssl 3.15.7
  • Grafana from 5.2 to 6.2
  • Icinga Web 2 Reporting from 0.9.0 to 0.9.1
  • Icinga Web 2 PDF Export from 0.9.0 to 0.9.1

Hi folks! I began loving computer since 1994, it was still the time of windows 3.1. Immediately I learned starting DOS games from the command promt, and while typing some white text on black background I felt like some hackish dude in a hollywoodian movie. Later during the studies at the university, I discovered the magic world of opensource, and it was love at first sight. Finally I got rid of BSOD's =) I love everything that is connected to some network, especially in a security perspective. My motto is: "With motivation, nothing is impossibile. It only requires more time."
