Exclude partition from disk usage monitoring process

-
Problem:
zimbra@mail:~/common/conf$ df -hT
Filesystem Type Size Used Avail Use% Mounted on
/dev/sda3      ext4        909G       86G      777G  10%       /
/dev/sda2      ext2        473M      65M      384M 15%       /boot
/dev/sda1      vfat         511M      3.4M     508M 1%         /boot/efi
/dev/loop0    squashfs 100M      100M    0         100%     /snap/core/11187
/dev/loop1    squashfs 62M        62M      0         100%     /snap/core20/1026
/dev/loop2    squashfs 43M        43M      0         100%     /snap/certbot/1201
/dev/loop3    squashfs 100M      100M    0         100%     /snap/core/11316
/dev/loop4    squashfs 43M        43M      0         100%     /snap/certbot/1280

We found /dev/loop0 to /dev/loop4 partition has 100% storage utilization. Hence, a system generated 
email is being received at admin@domain.com address.

Target: 
Stop these emails.

Solution:
zmlocalconfig -e zmstat_df_excludes="/dev/loop0:/dev/loop1:/dev/loop2:/dev/loop3:/dev/loop4"
zmstatctl restart
