How to ignore Junipers Unit 0 ports

Hey there,

my company is facing issues that Observium is reaching its limits in discovering and we want to reduce load on our discovery by ignoring so irrelevant port types.

JunOS always create a Unit 0 interface if a port is seen as untagged e.g. ge-0/0/0 and ge-0/0/0.0, we want to ignore all Port with a .0 at the end but how?

I have seen the $config['bad_if_regexp'][] but what would be the right expression?

$config['bad_if_regexp'][] = "/.[0]:/"; ? or what?
