running pt-query-digest for percona xtraDB cluster 8.0.19


Today want to make sure this toolkit works: 

but when I run it for the first time I say a new update is available and it said

“reading from STDIN…”

then it pends there for a long time, any one know what is the problem ?

what is the IP address this tools is downloading update?

I can simply ask IT mean to enable or check that IP for me.

Make sure you read that documentation page again. It explains how to properly use pt-query-digest. You need to provide a slow query log file.
