Welcome to version 4.7 of our NetEye v4 Unified Monitoring Solution. Following version 4.6, the new and updated features in this version focus mainly on a new Service Level Management module, Retention in Log Management, and the Tornado event processing engine.
Release Number: 4.7
Release Date: July 31, 2019
Release Type: Minor
Previous Release: 4.6
Upgrade Requirements: A NetEye 4.6 installation
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).
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.
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with this release, the Log Manager module will have a new configuration entry that supports the systematic deletion of outdated logs (from both rsyslog and Elasticsearch) according to a user-configurable retention policy.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.
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.
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:
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.
