Install Zabbix agent on TrueNAS

 In my previous article from 2018 I did mention how to install teh Zabbix agent on FreeNAS.

Since then two years are passed and FreeNAS has been replaced by TrueNAS provides the same functionality in a new version with a new name.

The steps for installation are remained the same, but you won't need to build the agent package yourself, you can use the packages provided from Zabbix for FreeBSD.

So lets see what you have to do now:

1. Download the binary package from the Zabbix webpage at https://www.zabbix.com/de/download_agents?version=4.0+LTS&release=4.0.25&os=FreeBSD&os_version=11.2&hardware=amd64&encryption=GnuTLS&packaging=Archive

It's no problem that FreeBSD 12.x is not listed, the 11.2 packages still work

2. Unpack the /bin and /sbin folders into /usr/local of your TrueNAS server

3. Unpack the /conf/* into /etc

4. Create a use and group zabbix so your agent wont run as root, you need to do this via GUI, otherwiese the account will be gone after reboot

5. Edit your /etc/zabbit_agentd:conf to match your needs

6. Enable daemon

echo 'zabbix_agentd_enable="YES"' >> /etc/rc.conf  

 

Create /etc/rc.d/zabbix_agentd:

#!/bin/sh

# PROVIDE: zabbix_agentd
# REQUIRE: DAEMON
# KEYWORD: shutdown
#
# Add the following lines to /etc/rc.conf.local or /etc/rc.conf to
# enable zabbix_agentd:
#
# zabbix_agentd_enable (bool): Set to NO by default.  Set it to YES to
#         enable zabbix_agentd.
#

. /etc/rc.subr

name="zabbix_agentd"
rcvar=zabbix_agentd_enable
start_precmd="zabbix_precmd"
required_files="/etc/zabbix_agentd.conf"

# read configuration and set defaultsc
load_rc_config "$name"
: ${zabbix_agentd_enable="NO"}
#: ${zabbix_agentd_pre:=/etc/${name}.pre.sh}

zabbix_agentd_conf="/etc/zabbix_agentd.conf"

if [ ! -z "$zabbix_agentd_conf" ] ; then
  zabbix_agentd_flags="${zabbix_agentd_flags} -c ${zabbix_agentd_conf}"
  required_files=${zabbix_agentd_conf}
fi

zabbix_precmd()
{
  if [ ! -z "$zabbix_agentd_pre" ] ; then
    if [ -e $zabbix_agentd_pre ] ; then
      . $zabbix_agentd_pre
    fi
  fi
}

command="/usr/local/sbin/${name}"

run_rc_command "$1"  run_rc_command "$1"

 Make executable:

1. chmod +x /etc/rc.d/zabbix_agentd
   

2. Start daemon:

   /etc/rc.d/zabbix_agentd start
   

3. Make config files persistent and survive reboots:

   cp /etc/rc.conf /conf/base/etc/
   cp /etc/rc.d/zabbix_agentd /conf/base/etc/rc.d/
   mkdir /conf/etc/zabbix_agentd
   cp /etc/zabbix_agentd.* /conf/base/etc/
   cp /etc/zabbix_agentd.* /conf/base/etc/ 

   Zabbix configuration
