I have this kind of logs

00:00:47: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to down
00:00:48: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan3, changed state to up
00:00:48: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/5, changed state to down

How can I extract severity and interface?

TIA

hey try this

index=your_index | rex field=_raw "%\w+-(?P<Severity>[^\-]+)-.*Interface\s(?P<Interface>[^\,]+)"

Also check this to see this in action
