Hello there,

in our setup, for every single host that has these snap-things, we have:

HOST=hostname
            DISK    %^/snap/.+ IGNORE
            INODE   %^/snap/.+ IGNORE

And nothing with a wildcard.
Think i can remember that if you have an entry with a wildcard, and after that another entry with an explicit hostname, that last found explicit entry COULD override the one with the wildcard; but not really sure about that, but worth a try.

Regards
Christian

Hi,

have you tried without the regex?
I have here

HOST=xyz
     DISK /mnt IGNORE
     INODE /mnt IGNORE

which is working.

Regards,
Torsten

I added this to my analysis.cfg no good...

HOST=*
     DISK %^/snap IGNORE
     INODE %^/snap/.+ IGNORE

this is my default analysis.cfg
