How do vassals manage themselves?

[Ellixhirion]

Hi all,

I play as the Duke of Flanders, I have 3 vassal counts, now from time to time, I see a revolt in one of my vassal counties.
But the vassal in question does nothing when a revolt breaks out in his county... I have to raise my own troops and go to his county to supress it.
I have to do it each time and its so frustrating that the vassal don't react on his own.
Is there a way to see the revolt risk of the vassal?
Cuz if i let things go, I have 2 vassals overruned by rebels.

You can see the revolt risk in the province screen.

It is most likely that their castles are not built up to weild enough of a force to defeat the rebels. This may change later though.

But one nice thing about rebels is that if you kill them yourself the province owner will be grateful towards you (+25).

I would still like it if it were like in Sengoku where vassals cleared up rebels throughout the country.

Vassals never raise a levy to go kill rebels in other peoples realms, even if the other guy is also a vassal under the same liege (as that is your job as liege).
Vassals also never raise the levy to fight rebels if it's smaller than the rebel stack, which it will be for every single province count at the beginning of the game.

So, if you keep your vassals weak and broken up enough to pose no threat to you, they're also too weak to properly defend against rebels.
Reward a strong duke with multiple counties and he'll take care of rebellions in his realm on his own. Of course, he may also decide to take care of you...
