--------------------------------------------------------------
Stuck on Zenoss 3.1.0 for now, lately my collectors have started failing to fetch zencommand and zenjmx config where these commands in data sources depend on a zProperty that is unchanged and inherited from the device type e.g. /Server/Oracle and not instantiated in the device level e.g. /Server/Oracle/devices/device_name. This used to work for ages but presumably some now untraceable change to the system has cased this to start happening every day.
The result when this exception happens is all commands for the device are deleted from the collection schedule of the device with coresponding "Deleting command" logs in the collector's zencommand.log. Usually a restart of the central hub and the collector will restore the commands for a while only to be deleted again when each collector next runs what I presume is a config cycle.
*Here is an example of the log lines in zenhub.log when zencommands fail:*
