"""The network plugin honours the hide_threshold_bytes it documents.
|
|
|
|
Both the reference configuration and docs/aoa/network.rst offer the option
|
|
under [network]:
|
|
|
|
[network]
|
|
hide_zero=True
|
|
hide_threshold_bytes=0
|
|
|
|
Nothing reports an option a plugin does not read -- the value simply stays at
|
|
the base class default of 0 and every interface with any traffic at all is
|
|
shown. These tests read the boundary back out of the views dict, so they fail
|
|
if the option stops being wired up again.
