If you want to exclude all cagefs-skeleton or some other virtfs, bind mounts and etc
zabbix_get -s xx.xx.xx.xx -k vfs.fs.discovery
“{#FSNAME}”:”\/usr\/share\/cagefs-skeleton\/dev\/pts”,
“{#FSTYPE}”:”devpts”},
“{#FSNAME}”:”\/usr\/share\/cagefs-skeleton\/dev\/shm”,
“{#FSTYPE}”:”tmpfs”},
“{#FSNAME}”:”\/usr\/share\/cagefs-skeleton\/lib”,
“{#FSTYPE}”:”ext4″},
Administration -> General -> Regular expressions -> New regular expression
Name: File systems for discovery – exclude cagefs
Expressions
Expression type: [Result is FALSE]
Expression: /cagefs-skeleton
Configuration -> Templates -> Template OS Linux -> Discovery rules -> Mounted filesystem discovery -> Filters -> Add
Type of calculation: A and B
A: {#FSNAME} matches @File systems for discovery – exclude cagefs
b: {#FSTYPE} matches @File systems for discovery
Also you need readd host to rediscover all mounted filesystems
Resolving Dependencies

—> Package zabbix-agent.x86_64 0:4.0.0-1.1alpha6.el6 will be installed
–> Processing Dependency: libpcre.so.0()(64bit) for package: zabbix-agent-4.0.0-1.1alpha6.el6.x86_64

Error: Package: zabbix-agent-4.0.0-1.1alpha6.el6.x86_64 (zabbix)
Requires: libpcre.so.0()(64bit)
You could try using –skip-broken to work around the problem
You could try running: rpm -Va –nofiles –nodigest
You should check if zabbix-release match your OS version than:
yum remove zabbix*
yum clean all
mv /var/cache/yum /var/cache/yum_old
yum install zabbix-agent
mv /etc/zabbix/zabbix_server.conf{,_back}
mv /etc/zabbix/zabbix_server.conf.rpmnew /etc/zabbix/zabbix_server.conf
vi /etc/zabbix/zabbix_server.conf
DBPassword=your_secret_password
service zabbix-server restart
