Hello
I have Zabbix in version 3.2.4.
I am running Ubuntu in version 18.04
I am trying to monitor change of specific folder. So, any time someone will change for example folder vfs.file.time[/home/samba/xxxx] I should seen it on Zabbix.

Is the directory permission so that it can be accessed by the user who is running Zabbix agent?
Is /home/samba the same as well?

Yes, this user has access to this directory.
