Zabbix

active check "vfs.fs.inode[/root/.cache/duplicity,pfree]" is not supported: Cannot obtain filesystem information: [13] Permission denied
active check "vfs.fs.size[/home/git-data/repositories/+gitaly/PackObjectsCache,pused]" is not supported: Cannot obtain filesystem information: [13] Permission denied

Investigate access right:

sudo -u zabbix /bin/bash

Solution:

apt install acl
setfacl -m u:zabbix:x /root
setfacl -m u:zabbix:x /root/.cache
 
setfacl -m u:zabbix:x /home/git-data
setfacl -m u:zabbix:x /home/git-data/repositories
setfacl -m u:zabbix:x /home/git-data/repositories/+gitaly

NOTE: gitlab-ctl reconfigure will change permissions to default.
