The event field is optional. Leave it empty and the preset will be
applied at all times.

Fautls are per channel per device. If a fault occures in a given
channel then all presets in that channel will be put on hold until the
fault is deleted or after the retry timeout has passed. The reasons
behind this are 1) to ensure a fault in one process (e.g. refreshing
stats) does not stop another unrelated process (e.g. device
provisioning); and 2) to ensure a group of presets in one channel are
applied atomically so that when using weights to override some values
we can guarentee there won't be any configuration "leakage".
