Hi,

I am trying to upgrade the underlying broker_module livestatus.o object file which i got it installed from 1.4.0p31-2.el7.x86_64. I am trying to upgrade it to 1.5.0p12-el7-38.x86_64. I am using it for Nagios Core 4.4.3 in my setup.

Code: Select all

#cp /opt/omd/versions/1.5.0p12.cre/lib/mk-livestatus/livestatus.o /usr/lib64/check_mk/livestatus.o

[1552120195] Error: Module loading failed. Aborting.

I have rolled it back to the previous working state and it is working fine. The details of nagios.log are as below :-

You need to recompile livestatus for nagios 4. Please uninstall the old module and follow this instruction:

wget https://mathias-kettner.de/support/1.5. ... 0p9.tar.gz
tar xzf mk-livestatus-1.5.0p9.tar.gz
cd mk-livestatus-1.5.0p9
./configure --with-nagios4

You'll see this error:
error: *** A compiler with support for C++17 language features is required.
Run these commands:
1. yum install centos-release-scl
2. yum install devtoolset-7-gcc-c++
3. yum install rrdtool-devel
(if you get some error with GPG keys please install the nagios repo for Cent7 from here) https://repo.nagios.com/?repo=rpm-cento ... 1496153015
4. yum install boost*
5. scl enable devtoolset-7 bash
6. ./configure --with-nagios4

cd src
make install

Create broker_module line in nagios.cfg and restart nagios

broker_module=/usr/local/lib/mk-livestatus/livestatus.o /usr/local/nagios/var/rw/live

service nagios restart

Hi Nikita Polovenko,

I wanted to list the latest mk-livestatus software version using https://mathias-kettner.de/support/ and it prompted me to provide username and password. I have attached the screenshot for your reference.

For example the complete URL :- https://mathias-kettner.de/support/1.5.0p12/mk-livestatus-1.5.0p12.tar.gz

Please comment and i look forward to hearing from you.

@kaushalshriyan, Check_MK is a third party software and looks like this is the link to their support portal? We don't have any access to that.
From what I've read their community edition is free but the support is paid. More can be found here:
