Deploy

The deploy script is not intended to advise which approach you should implemented nor deploy the sudoers configuration but the user that will run the script needs be running with sudo privileges.

There are two options to setting up sudoers for the user:

Provided sudo all

~# cat /etc/sudoers.d/user_zabbix
Defaults:zabbix !syslog
Defaults:zabbix !requiretty

zabbix	ALL=(ALL)  NOPASSWD:ALL
~#

Limited acccess to run command with sudo

~# cat /etc/sudoers.d/user_zabbix
Defaults:zabbix !syslog
Defaults:zabbix !requiretty

zabbix ALL=(ALL) NOPASSWD: /usr/sbin/glusterd *
zabbix ALL=(ALL) NOPASSWD: /usr/bin/gluster *
~#

Zabbix

Please ensure that the zabbix user has the right permissions before continue with the installation.

~# git clone https://github.com/sergiotocalini/glusix.git
~# sudo ./glusix/deploy_zabbix.sh
~# sudo systemctl restart zabbix-agent

Note: the installation has to be executed on the zabbix agent host and you have to import the template on the zabbix web.

zabbix agent user sudo

zabbix agent user needs sudo privs on gluster and glusterd commands

other than that, awesome work, thanks for providing this !!

I guess I add that requirement to the README.

volume_status.sh display_units not working on fedora 30

Everything worked, except "Disk total" and "Disk free", which both showed 0.

After debugging I came up with a patch that fixed it for me.

glusix[volume_status, prod-glusterfs, size, free] incorrectly reports the size of the arbiter node

ref: https://docs.gluster.org/en/latest/Administrator%20Guide/arbiter-volumes-and-quorum/

I have a glusterfs configuration of two data notes and a arbiter node (replica 3 arbiter 1). The arbiter node has a small disk. Now glusix[volume_status, prod-glusterfs, size, free] incorrectly assumes the arbiter node is the smallest node of the replica, and glusix[volume_status, prod-glusterfs, size, free] reported the free size of the arbiter node.
