TrueNAS ZenPack

Monitoring of FreeNAS/TrueNAS servers with auto-discovery feature for pools and datasets


The ZenPack Catalog has moved to its new home at https://www.zenoss.com/product/zenpacks as of January 17, 2017. The following information may be out of date, and this page will eventually be removed.


This ZenPack is developed by the Zenoss user community and supported via our online forums. Zenoss, Inc. does not provide direct support for this ZenPack.


Version 0.9.0- Download
Compatible with Zenoss Core 4.2.x, Zenoss Core 5.0.x



This ZenPack relies on SNMP to extract performance metrics as well as discovering pools and datasets.Therefore, the correct community has to be set. Apart from SNMP-based monitoring, FreeNAS/TrueNAS events are also translated to Zenoss events. Dismissing them on the web interface clears them on Zenoss. Syslog monitoring can also be enabled on the web interface regardless of this ZenPack's installation.


Before installing the ZenPack, be sure to install PyYAML as the Zenoss user:

   easy_install PyYAML

The ZenPack provides a device class named TrueNAS nested under /Server/Linux. FreeNAS/TrueNAS devices should be added to that class, configured then modelled. Below a list of zProperties added by the ZenPack.

zProperty Description
zTrueNASLogin FreeNAS/TrueNAS web login. Used to extract alerts from the API
zTrueNASPass FreeNAS/TrueNAS web password. Used to extract alerts from the API
zTrueNASIgnorePools List of pools to ignore on modeling.
