1. Telepítsd fel a MacPorts-ot és játszásdiból indítsd el a munin MacPorts-os telepítését, hogy legyen SVN kliens:

   port install munin +server

   Le lehet állítani pár másodperc múlva

2. Telepítsd fel az AppStore-ból az Xcode programot
3. Indítsd el az Xcode programot és telepítsd fel a Command Line Tools-t:
   1. Preferences → Downloads
   2. Itt kattints a csomag melletti kis letöltés ikonra
4. Nyiss egy rendszergazdai terminált (sudo -s)
5. Felhasználó és csoport létrehozása:

   dscl . create /Groups/munin PrimaryGroupID 4949
   dscl . create /Users/munin UniqueID 4949
   dscl . create /Users/munin PrimaryGroupID 4949
   dscl . create /Users/munin UserShell /bin/false
   dscl . create /Users/munin NFSHomeDirectory /usr/local/munin/var/run/munin
   dscl . create /Users/munin RealName Munin
   dscl . create /Groups/munin GroupMembership munin
   defaults write /Library/Preferences/com.apple.loginwindow HiddenUsersList -array-add munin

6. Takarítás:

   rm -rf /usr/src/munin
   rm -rf /usr/local/munin
   rm -rf /opt/munin
   rm -rf /etc/opt/munin/
   rm /Library/LaunchDaemons/org.munin-monitoring.munin-node.plist

7. Környezet kialakítása:

   export LANG=C
   mkdir -p /usr/local/munin/var/run/munin
   chown munin:munin /usr/local/munin/var/run/munin

8. Forráskód letöltése:

   mkdir -p /usr/src/munin
   cd /usr/src/munin
   svn checkout "svn://munin.projects.linpro.no/munin/trunk"
   cd /usr/src/munin/trunk

9. Forrás átalakítása a Mac rendszerhez:

   Makefile.config

   ...
   # Default user to run the plugins as
   PLUGINUSER := munin
   ...

10. Forráskódok forgatása:

    make install-common
    make install-node
    make install-node-plugins
    make install

11. Pluginek bekapcsolása:

    /opt/munin/sbin/munin-node-configure --suggest --shell | sh
    
    rm /etc/opt/munin/plugins/munin_stats

12. if_err_ plugin javítása:

14. Munin config Mac-esítése:

    cd /etc/opt/munin/

    munin-node.conf

    log_level 4
    log_file Sys::Syslog
    pid_file /usr/local/munin/var/run/munin/munin-node.pid

15. Daemon indítása:

    launchctl load org.munin-monitoring.munin-node.plist

16. Innentől pedig kövessük a Linux-os munin-node beállítást!

1. Telepítsd fel a binárist:

   port install smartmontools

2. Munin beállítása:

   ln -s /opt/munin/lib/plugins/smart_ /etc/opt/munin/plugins/smart_disk0

   /etc/opt/munin/plugin-conf.d/munin-node

   [smart_disk0]
   user root
   env.smartpath /opt/local/sbin/smartctl

3. Daemon újraindítása:

   cd /Library/LaunchDaemons
   launchctl unload org.munin-monitoring.munin-node.plist
   launchctl load org.munin-monitoring.munin-node.plist

• https://www.smartmontools.org/wiki/Supported_USB-Devices

Ebben az esetben a típust nekünk kell kézzel megadni a fenti linken elérhető táblázat alapján:

/etc/opt/munin/plugin-conf.d/munin-node

[smart_chieftec-usb-disk1]
env.smartargs -d sat -a

1. A szükséges git repo klónozása:

   mkdir -p /opt/git-3th
   git clone 'https://github.com/andras-tim/contrib.git' /opt/git-3th/munin-monitoring_contrib

2. Pluginek bekötése, beállítása:

   cd /opt/git-3th/munin-monitoring_contrib/plugins/system
   ls dar_* |
       grep -v 'dar_uptime' | 
       while read a 
       do
           ln -s "/opt/git-3th/munin-monitoring_contrib/plugins/system/$a" /etc/opt/munin/plugins/
           "/etc/opt/munin/plugins/$a" autoconf yes
       done

3. Pluginek tesztelése:

   /opt/munin/sbin/munin-run dar_cpuusage
   /opt/munin/sbin/munin-run dar_memusage
   /opt/munin/sbin/munin-run dar_swap
   /opt/munin/sbin/munin-run dar_vmstat

4. munin-node újraindítása:

   launchctl unload /Library/LaunchDaemons/org.munin-monitoring.munin-node.plist
   launchctl load /Library/LaunchDaemons/org.munin-monitoring.munin-node.plist
