Zabbix Monitoring 4.2 Release

Das Zabbix Team hat avor wenigen Tagen die neue Hauptversion 4.2.0 veröffentlicht. Die Entwickler des Enterprise Class Open Source Monitoring Tool, behebten über 300 Fehler und führten über 80 Verbesserungen und Neuerungen durch.

Ca. 6 Monate dauerte die Entwicklung von Version 4.0. auf 4.2, die nun mehr Systeme wie Raspberry Pi unterstützt. Und auch der Agent für Mac OS X ist neu. Viel Augenmerk setzten die Entwickler auf die Performance, die nun eine höhere Geschwindigkeit bei Abfragen durch den Agent durchführt. Weiterhin wird die Sprache PromQL unterstützt, Fehler nun besser überprüft und abgefangen und Abfragen können mittels JavaScript verarbeitet werden.

In Version 4.2 können nun auch Agenten Processing-Abfragen auswerten. Zabbix kann Systeme nun besser erkkennen und unterstützt Low-Level-Discovery (LLD). Das Tag-Management wurde vereinfacht und TimescaleDB als Datenablage wird unterstützt.

Auch an die Oberfläche wurde Hand angelegt und überarbeitet. So lassen sich Preprocessing-Regeln nun direkt testen und Informationen zu entfernten Servern direkt aus der Netzwerkübersicht aufrufen.
