    Hi, thank for your reply. I use SSH to my CentOS server, use redis-cli => info and got something:

    If I use: redis-cli => KEYS *metrics*
    I got:

    127.0.0.1:6379> KEYS *metrics*
    1) "my-domain-1.comwp_1a43c2f:redis-cache:metrics"
    2) "my-domain-2.comwp_e2cb081:redis-cache:metrics"
    3) "my-domain-3.comwp_648a5bd:redis-cache:metrics"
    4) "my-domain-4.comwp_b962ee3:redis-cache:metrics"

    I have 30 website (domains) on my server

    Is it what you need me to provide?

    Thanks

    I wonder if this is an escaping issue with your fancy prefixes.

    Would you mind reporting this issue on GitHub and we can take it from there?
