Update as of 16/04/18

Create a  service user: zabbix

Check if the gid you will use, is still available, for users: sudo dscl . -list /Users UniqueID

Groups: sudo dscl . -list /Groups UniqueID

sudo dscl . -create /Groups/zabbix gid 301
sudo dscl . -create /Groups/zabbix RealName “Zabbix Server Group"
sudo dscl . -create /Groups/zabbix passwd "*"


sudo dscl . -create /Users/zabbix
sudo dscl . -create /Users/zabbix uid 301
sudo dscl . -create /Users/zabbix gid 301
sudo dscl . -create /Users/zabbix NFSHomeDirectory /var/empty
sudo dscl . -create /Users/zabbix UserShell /usr/bin/false
sudo dscl . -create /Users/zabbix RealName "Zabbix Server"
sudo dscl . -create /Users/zabbix passwd "*"

For zabbix clients 3.4 on mac os, we’ll also need PCRE as noted here https://www.zabbix.com/documentation/3.4/manual/installation/install

Switch to Download folder of current user and download the source package.

cd /Downloads
curl --remote-name ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.41.tar.gz

Extract the archive and move into the folder.

tar -xzvf pcre-8.41.tar.gz

sudo mv pcre-8.41 /etc/pcre-8.41

Configure, compile and install into  /etc/pcre-8.41

sudo ./configure --prefix=/etc/pcre-8.41
sudo make
sudo make install 

Create a symbolic link to /usr/local/pcre.

sudo ln -s /etc/pcre-8.41 /usr/local/pcre 

We’ll need xcode for zabbix to compile on a Mac osx server (so once compiled you can skip this step, until and including the line “./configure –enable-agent”. Just copy the already compiled agent from an existing mac osx)
command-line tools:

xcode-select --install

Download zabbix source code: https://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/3.2.0/zabbix-3.2.0.tar.gz/download (http://www.zabbix.com/download.php)
Untar

cd /Users/administrator/Downloads (or whatever)
curl -L https://sourceforge.net/projects/zabbix/files/ZABBIX%20Latest%20Stable/3.4.7/zabbix-3.4.7.tar.gz/download -o zabbix-3.4.7.tar.gz
tar -zxvpf zabbix-3.4.7.tar.gz

Switch to the tarball directory

cd zabbix-3.4.7

Make the installation directories and run the configure script with the –enable-agent switch

sudo mkdir -p /usr/local/etc /usr/local/sbin
sudo ./configure --enable-agent --with-libpcre=/etc/pcre-8.41
sudo make
sudo make install

Copy the configuration file to the local etc directory:

sudo cp ./conf/zabbix_agentd.conf /usr/local/etc/

Copy the daemon file to the local sbin directory

sudo cp ./src/zabbix_agent/zabbix_agentd /usr/local/sbin
sudo nano /usr/local/etc/zabbix_agentd.conf

Start the agent:

/usr/local/sbin/zabbix_agentd

To autostart the zabbix agent with a reboot of MAC OSX

Make the following file: “/Library/LaunchAgents/org.macports.zabbix_agent.plist”

sudo nano /Library/LaunchAgents/org.macports.zabbix_agent.plist

Contents of the file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">


<dict>
<key>Label</key>
<string>org.macports.zabbix_agent</string>
<key>RunAtLoad</key>
<true/>
<key>ProgramArguments</key>

<array>
<string>sh</string>
<string>/etc/startzabbix.sh</string>
</array>
</dict>
</plist>

test your file with: plutil /Library/LaunchAgents/org.macports.zabbix_agent.plist

Let’s create a startup script for zabbix (yes, i am aware it is “strange” to create a bash file, while i could copy paste the same command directly in the plist file, but i’ve seen, how can i say, various result with different mac os versions, it seems this works best overall on all mac os versions):

sudo nano /etc/startzabbix.sh

which says:

#!/bin/bash
/usr/local/sbin/zabbix_agentd

make it runnable:

sudo chmod a+x /etc/startzabbix.sh

Launch the launchctl file with (so you don’t need to reboot to test the plist, no sudo!): launchd /Library/LaunchAgents/org.macports.zabbix_agent.plist

Last: Make the host in zabbix and add the mac template on it.
Also don’t forget to open up port 10050 in the firewall of the mac osx server
