Всем привет,
подскажите способы получить в результате net.if.discovery список только активных eth интерфейсов в Linux?

Подвопрос: вызовом какой "команды" zabbix-agent получает список интерфейсов (ifconfig, ip) и можно ли там как-то отфильтровать только активные интерфейсы (например, при "ip a" фильтровать по NO-CARRIER )?

Code:

[root@zabbix ~]# strace zabbix_agent -t 'net.if.discovery'

Спасибо, а какой-нибудь work-around можете подсказать?

Писать свой дискаверинг скриптами.

Перепишите дискавер скрипт, делов то

Подвопрос: вызовом какой "команды" zabbix-agent получает список интерфейсов (ifconfig, ip) и можно ли там как-то отфильтровать только активные интерфейсы (например, при "ip a" фильтровать по NO-CARRIER )?

А чем вам мешает то, что мониторятся все имеющиеся интерфейсы? ну на down будут нули постоянно, база чуть раздувается, но это не существенно.

Триггеры пишете на основе "событий", а не на основе "состояния". То есть не "интерфейс $if down", а "интерфейс $if перешел в состояние выключен"

**_=Alex=_** · 26-07-2015, 20:02

Тогда будет просьба - внести такую возможность в след. версии.
