FreeNAS (for Zenoss)
As we all know, FreeNAS is powerful enterprise-grade storage with a comprehensive user interface designed to make ZFS filesystem easier to use.
We've answered to a community need to develop a dedicated zenpack for this tool.
The goal here is to be able monitor FreeNAS/TrueNAS devices with auto-discovery for pools and datasets. We rely on SNMP to extract the needed performance metrics.
