Full-Stack Monitoring + AIOps

ZenPacks are plug-ins that make it easy for customers to collect real-time health and performance metrics from every system in their environment. There are four categories of ZenPacks — Commercial, Open Source, Subscription and Community — which are aligned by two key attributes: who has access to the ZenPack and how it is supported. Many ZenPacks are created by Zenoss and are released freely, while others are only available via a paid subscription or service agreement. Community ZenPacks are created and supported by their community members.
