Zabbix Agent does not return iscsi filesystems

[brentg]

I have a couple of Linux servers with iscsi (xfs) filesystems mounted on them that aren't showing up in filesystem discovery. I've found that running

zabbix_get -s [host] -k vfs.fs.get

from my Zabbix server does not include those filesystems. If I run

zabbix_agent2 -t vfs.fs.get

as root on one of the impacted hosts, it does include those filesystems in the list. However, if I instead run

sudo -u zabbix zabbix_agent2 -t vfs.fs.get

then those filesystems disappear. I changed the Zabbix Agent 2 service file to run the agent as root instead of zabbix, restarted the agent, and suddenly the iscsi filesystems do get returned by zabbix_get. Changing the agent back to the zabbix user causes them to disappear again. I've found no output in zabbix agent2 logs, and nothing that appears relevant in selinux logs. How can I get these file systems to be included by the Zabbix Agent?

Running zabbix-agent2 7.4.0 on Oracle Linux 9.

Sure enough. I had previously tested the mount command as the zabbix user and that worked. But this morning I tried df and that omitted them. A bit of quick research showed that I needed to grant execute permissions on the directory structure that the mount points are on. Now I have data! Thanks!

I think you may need to review those mounting options/permissions there. Seems like ordinary users do not see them... or have no permissions to access them....
