Install Icinga2 with RedHat or CentOS

Python compatibility

To use the Open Integration Manager for Agent-based integrations, Python version>= 3.8.0 and an Agent version >= 10.2 are required.

Prerequisites

python >= 3.8.0 is required for the latest version of the BigPanda Agent, and will be installed by the BigPanda Agent installer if it does not exist.

Note: Access to JFrog, pypi, and yum repositories are required to install all dependencies.

Install the BigPanda Agent on RedHat or CentOS

Connect to the host where your agent server is installed, and install the BigPanda agent package.

Add a new yum repository to download the BigPanda agent package.

 $ sudo vim /etc/yum.repos.d/bigpanda.repo
 
...

 [BigPanda]
 name=BigPanda
 baseurl=https://bigpandaio.jfrog.io/artifactory/int-rpm/bigpanda/agents/
 enabled=1
 gpgcheck=0
 gpgkey=https://bigpandaio.jfrog.io/artifactory/int-rpm/bigpanda/agents/repodata/repomd.xml.key
 repo_gpgcheck=1

Update the yum repos list to add the BigPanda repo.
```
 $ sudo yum update 
```

List all available packages with duplicates in the BigPanda repo.

 $ sudo yum list --showduplicates bigpanda-agent | expand
 
Available Packages
 bigpanda-agent.x86_64       10.2.0-1.el7       BigPanda
 bigpanda-agent.x86_64       10.2.0-1.el8       BigPanda
 bigpanda-agent.x86_64       10.2.0-1.el9       BigPanda
 bigpanda-agent.x86_64       10.3.0-1.el7       BigPanda
 bigpanda-agent.x86_64       10.3.0-1.el8       BigPanda
 bigpanda-agent.x86_64       10.3.0-1.el9       BigPanda

Note: This does not send the OS version to JFrog, so we need to cherry-pick the correct version for the OS.

Install the BigPanda agent package.
```
 $ sudo yum install bigpanda-agent-<version-number> 
```
Note: Append the version number to the package name, (i.e. bigpanda-agent-10.3.0-1.el7).

Note: For the OIM, bigpanda-agent v10.0.0+ is required.

Configure Icinga2

The BigPanda agent uses Icinga2 status.dat and compatibility log to generate alerts. Both files will be created by Icinga2 only after enabling the compatlog and statusdata features. To enable those feature, run the following commands on your Icinga2 server:

$ sudo icinga2 feature enable compatlog statusdata
$ sudo service icinga2 restart

Configure the BigPanda Agent

Generate the agent's configuration file:

$ sudo bigpanda-config --init --token <Your Org Bearer Token>

And add the Icinga2 plugin with the application key you created in step 1:

$ sudo bigpanda-config --add icinga --app-key <Your App Key>

When prompted, specify the locations of icinga.log, status.dat, and objects.cache files.

The script output should look like this:

Log File Path: /var/log/icinga/compat/icinga.log
Status Dat Path: /var/cache/icinga/status.dat
Objects Cache Path: /var/cache/icinga/objects.cache

Of course, the actual paths will depend on your installation.

Update Permissions

Give the agent read permissions to the objects.cache, status.dat and log files. A possible way to do it:

$ sudo usermod -a -G "<GROUP OF OBJECT CACHE FILE>,<GROUP OF LOG FILE>,<GROUP OF STATUS DAT FILE>" bigpanda

Start the BigPanda Agent

Start the BigPanda agent service by running the following command:

$ sudo systemctl start bigpanda

if systemd is not installed, use the alternative command.

 $ sudo service bigpanda start

Verify the agents have started:

$ systemctl status bigpanda

Troubleshooting

You should have the bigpanda directory with the bigpanda.conf config file located at /etc/bigpanda/bigpanda.conf.

If the configs are missing or the package did not set up correctly, stop the service the and reinstall the package.

  $ sudo systemctl stop bigpanda

if systemd is not installed, use the alternative command:

 $ sudo service bigpanda stop

To reinstall the package:

  $ sudo yum reinstall -y bigpanda

The agent is installed using a virtual environment, so the virtualenv package is installed by either yum/apt-get or pip , and gets installed by the installer. You could also pre-install this package.
All packages are installed in the virtual environment, which is located at /opt/bigpanda/venv.
To work within the virtual environment, you need to activate it, source /opt/bigpanda/venv/bin/activate.
Once activated, you can view all python packages within the virtual environment, pip list.
Python packages, including the bigpanda module, are installed in the virtual environment, /opt/bigpanda/venv/lib/<python version>/site-packages/ or /opt/bigpanda/venv/lib64/<python version>/site-packages/.
Once you’re done working with the virtual environment, you deactivate it with the deactivate command.
All bigpanda binaries in /usr/bin/ now call the virtual environment, and should point to /opt/bigpanda/venv/bin/python3 to access installed packages.
If you need to reinstall packages, or update a package, do so with the following workflow:

Activate the virtual environment:
```
source /opt/bigpanda/venv/bin/activate
```

Install packages into the virtual environment, this should be calling:

/opt/bigpanda/venv/bin/pip
pip install -r /etc/bigpanda/agent/requirements.txt

Deactivate the virtual environment
```
deactivate
```

Success

You should be able to see all your active alerts from this integration in the Incidents tab.
