## 9.4. MKLiveStatus Integration

### 9.4.1. Introduction

MKLiveStatus is a module written by Mathias Kettner interfacing Icinga (or Nagios) with several addons like NagVis or Thruk. Unless you need a database for storing historical data this might be a good choice because it's quite small and easy to install. Please have a look at the official website for a complete documentation as the following lines are just a very short guide on how to install and configure MKLiveStatus for Icinga. We assume that you have installed Icinga in /usr/local/icinga.

### 9.4.2. Installation / Configuration

1. Download the software and compile it (please check the website for the latest version)

        wget http://mathias-kettner.de/download/mk-livestatus-1.2.2.tar.gz
        tar xzvf mk-livestatus-1.2.2.tar.gz
        cd mk-livestatus-1.2.2
        ./configure --prefix=/usr/local/icinga --exec-prefix=/usr/local/icinga
        make
        cp src/livestatus.o /usr/local/icinga/bin

2. Edit icinga.cfg to integrate the module. Please make sure that the directory /usr/local/icinga/var/rw exists and is writable for the Icinga user. It should be the same directory used for the command file (mostly icinga.cmd). "live" is a socket and it will only be present during runtime of the module.

   `broker_module=/usr/local/icinga/bin/livestatus.o /usr/local/icinga/var/rw/live`

   | Note
   Starting with Icinga 1.4 you can use the new module definition in one of your object configuration files instead of specifying a broker_module entry:
        define module{
               module_name    mklivestatus
               path           /usr/local/icinga/bin/livestatus.o
               module_type    neb
               args           /usr/local/icinga/var/rw/live
               }

3. Restart Icinga

       service icinga restart

   or

       /etc/init.d/icinga restart

4. Check operation

        ps -ef | grep livestatus
        ls -la /usr/local/icinga/var/rw/live

   If there is no running process and/or no socket then please check the Icinga log file and resolve any errors.
