Re: filtering out passwords from diagnostic snapshot

 

Thank you, Bogdan.

Is "password sanity checks" built-in feature in Elasticsearch? I've not
managed to find anything about this feature. What exactly do you mean
taking about "password sanity checks"? How can index help if the password
looks like "admin" or something like this?
