.. explains why the "Host 'host_name' is blocked" error may occur.  

But I do not find an option to display 'host connect_status'.  There is no SHOW statement and no data in Information_Schema exposing how many connect_errors were recorded for evey host (correct me if I am wrong and I will be happy!)

How to repeat:
see above.

Suggested fix:
consider to add statements



SELECT host, connect_errors FROM I_S

(In my understanding the server must store this information in memory already.  Why not use I_S then? It should be possible to monitor and alert the issue *before* connections are refused)

One concern could be that this information should be privileged information (require SUPER privilege maybe)
