Centreon Engine

Warning This repository is now deprecated. Please switch to Centreon Collect.

Centreon Engine is a fast and powerful open-source monitoring scheduler. It is a low-level component of the Centreon software suite.

Centreon Engine is released under the General Public License version 2 and is endorsed by the Centreon company.

This project was started as a fork of Nagios, the well known open-source monitoring application. While keeping its configuration file format and its stability we improved it in several ways:

• Reduced startup time
• Faster standard check execution engine
• New light check execution system (connectors)
• On-the-fly configuration reload
• Less obscure configuration options
• Frequent bugfix releases

Just give it a try!

Installing from binaries

Centreon Engine is a low-level component of the Centreon software suite. If this is your first installation you would probably want to install it entirely.

Centreon (the company behind the Centreon software suite) provides binary packages for RedHat / CentOS. They are available either as part of the Centreon Platform or as individual packages on our RPM repository.

Once the repository installed a simple command will be needed to install Centreon Engine.

yum install centreon-engine

Fetching sources

Beware that the repository hosts in-developement sources and that it might not work at all.

Stable releases are available as gziped tarballs on Centreon's download site.

Compilation (quickstart)

This paragraph is only a quickstart guide for the compilation of Centreon Engine.

Centreon Clib should be installed before installing Centreon Engine. If you do not have Centreon Clib please refer to the centreon-clib project.

CentOS / Debian / Raspbian

Compilation of these distributions is pretty straightforward.

You'll need to download the project and launch the cmake.sh script to prepare the compilation environment:

git clone https://github.com/centreon/centreon-engine
cd centreon-engine
./cmake.sh

Now launch the compilation using the make command and then install the software by running make install as priviledged user:

cd build
make
make install

Other distributions

If you are on another distribution, then follow the steps below.

Check if you have these packages installed (Note that packages names come from CentOS distributions, so if some packages names don't match on your distribution try to find their equivalent names): git, make, cmake, gcc-c++, python3.

For the projet compilation you need to have conan installed. Try to use the package manager given by your OS to install conan. ('apt' for Debian, 'rpm' for Red Hat, 'pacman' for Arch Linux, ...). It is prefered to install gcc before conan.

Example:

apt install conan

If it does not work, conan can be installed with pip3:

pip3 install conan

All the dependencies pulled by conan are located in conanfile.txt. If you want to use a dependency from your package manager instead of conan, you need to remove it from conanfile.txt.

You can now prepare the compilation environment:

git clone https://github.com/centreon/centreon-engine
mkdir -p centreon-engine/build
cd centreon-engine/build
conan install --build missing ..
cmake -DWITH_PREFIX=/usr -DWITH_PREFIX_BIN=/usr/sbin -DWITH_USER=centreon-engine -DWITH_GROUP=centreon-engine -DCMAKE_BUILD_TYPE=Release -DWITH_RW_DIR=/var/lib/centreon-engine/rw -DWITH_PREFIX_CONF=/etc/centreon-engine -DWITH_VAR_DIR=/var/log/centreon-engine -DWITH_PREFIX_LIB=/usr/lib64/centreon-engine ..

This will look for required dependencies and print a summary of the compilation parameters if everything went fine.

Now launch the compilation using the make command and then install the software by running make install as priviledged user:

make
make install

Verify the /etc/centreon-engine directory.

Usually, its content is filled by the Centreon web interface, owned by the apache user.

A command like the following may be necessary:

chown -R apache:apache /etc/centreon-engine/*

You're done!

Bug reports / Feature requests

The best way to report a bug or to request a feature is to open an issue in GitHub's issue tracker.

Please note that Centreon Engine follows the same workflow as Centreon to process issues.

For a quick resolution of a bug your message should contain:

• The problem description
• Precise steps on how to reproduce the issue (if you're using Centreon web UI tell us where you click)
• The expected behavior
• The Centreon products versions
• The operating system you're using (name and version)
• If possible configuration, log and debug files

Contributing

Contributions are much welcome! If possible provide them as pull-requests on GitHub. If not, patches will do but describe against which version/commit they apply.
