prometheus HostDown alert doesn't say what node

In the anti-censorship team we've got a HostDown alert, but it doesn't say what node is down:

I wonder if we should receive those alerts at all, as I guess we can't fix them ourselves. It might be useful to know that a server is down, but will be nice to know which.
