Mounted filesystem discovery when using dockbix-agent-xxl

[oldunclez]

I am running Zabbix 4.2.4 server , and want to monitor a ubuntu 16.04 host .

How I run dockbix-agent-xxl :

docker run
--name=dockbix-agent-xxl
--net=host
--privileged
-v /:/rootfs
-v /var/run:/var/run
--restart unless-stopped
-e "ZA_Server=<ZABBIX SERVER IP/DNS NAME/IP_RANGE>"
-e "ZA_ServerActive=<ZABBIX SERVER IP/DNS NAME>"
-d monitoringartist/dockbix-agent-xxl-limited:latest

And in the zabbix server web dashboard , I link two templates to this host :

Template App Docker
Template OS Linux

After a while , I found the following zabbix items:

Mounted filesystem discovery: Used disk space on /etc/hosts
Mounted filesystem discovery: Free inodes on /etc/hostname
Mounted filesystem discovery: Total disk space on /rootfs
Mounted filesystem discovery: Total disk space on /rootfs/data01
Mounted filesystem discovery: Free disk space on /etc/hosts
Mounted filesystem discovery: Total disk space on /etc/resolv.conf
Mounted filesystem discovery: Total disk space on /etc/hosts
Mounted filesystem discovery: Used disk space on /rootfs
Mounted filesystem discovery: Used disk space on /rootfs/data01
Mounted filesystem discovery: Used disk space on /etc/resolv.conf
Mounted filesystem discovery: Used disk space on /etc/hostname
Mounted filesystem discovery: Total disk space on /etc/hostname

But in fact , there are only two mounted filesystems ( / and /data01) on this ubuntu 16.04 host.

My question is that :
What should I do to make Mounted filesystem discovery to / and /data01 ,.
Thank you !
