Zabbix monitoring of Samba mounts defined in /etc/fstab

This project is composed by two shell scripts, a Zabbix template and a zabbix-agent configuration file:

• The script discover_smb.sh checks for mount points defined in /etc/fstab with cifs type
• The script smb_check.sh reads the exit of mount command, and checks if every mount point in fstab is mounted
• The template has discovery items that read those values and activates triggers. This repository was created using Zabbix 4.4.5 and several GNU/Linux CentOS 7 OS servers. It may work on previous zabbix versions, but I couldn't test it.

Features

• Discover shared samba resources, mounted in the file system
• Receive an alert if any resource is not listed as mounted

Features planned

• Define mount types other than cifs

Installation

1. Download the necessary files or clone this project anywhere zabbix user can access.

2. Put zabbix-agentd.d/sambaMounts.conf in zabbix agent directory, normally /etc/zabbix/zabbix-agentd.d/. Edit this file if you don't use the default /var/lib/zabbix folder for shell scripts.

3. Put smb_check.sh and discover_smb.sh in /var/lib/zabbix folder (or the one you defined in the previous file).

4. Now restart the Zabbix agent service.

5. Import template/samba_mount_template.xml in Zabbix and assign it to your desired hosts.
