Install Nagios with RedHat or CentOS
Configure the BigPanda agent to send monitoring alerts from Nagios.
The BigPanda agent is a low-footprint utility installed on the master host of your monitoring tool. It consumes alerts from the tool in real-time and then transmits them to BigPanda via TLS-encrypted HTTP calls.
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.
-
Ensure python3 is installed with the following command:
$ sudo yum install -y python3
-
Verify the install with the following commands:
$ python3 --version $ pip3 --version
Note: If pip3 was not installed as a dependency, it can be installed with sudo yum install -y python3-pip
.
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 Nagios 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: RHEL or Centos 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 the BigPanda Agent
-
Generate the agent's configuration file:
$ sudo bigpanda-config --init --token <Your Org Bearer Token> $ sudo bigpanda-config --add nagios-notifications --app-key <Your App Key>
-
Add the Nagios user to the bigpanda group by running the following command:
sudo usermod -a -G bigpanda <Nagios username>
-
Start the BigPanda agent service by running the following command for RHEL or Centos 7 & 8:
sudo service bigpanda start
Configure Nagios
Configure Nagios to send notifications to BigPanda.
-
Edit the main configuration file (
nagios.cfg
). The default location is:/usr/local/nagios/etc/nagios.cfg
.- Add the following line:
cfg_file=/etc/bigpanda/bigpanda-contact.cfg
- Ensure that notifications are enabled
enable_notifications=1
- Add the following line:
-
In the file where your host objects are defined (for example,
templates.cfg
):- Add the
bigpanda
contact to thecontact_groups
. - Set the
notification_options
for the host to:d,r,u,f,s
.
For example:
define host{ name generic-host contact_groups admins,bigpanda notification_period 24x7 notification_options d,r,u,f,s }
If the
contact_groups
option is not already listed in your definitions, you can add it. - Add the
-
In the file where your service objects are defined (for example,
templates.cfg
):- Add the
bigpanda
contact to thecontact_groups
. - Set the
notification_options
for the service to:c,r,w,u,f,s
.
For example:
define service{ name generic-service check_period 24x7 contact_groups admins,bigpanda notification_interval 60 notification_period 24x7 notification_options c,r,w,u,f,s }
If you have already configured notification options on a more specific template or definition, those settings will take precedence over the generic settings.
To get the most out of this integration, ensure all of the desired notifications are sent to BigPanda.
- Add the
-
Restart the Nagios service.
- RHEL or Centos
sudo service nagios restart
- RHEL or Centos
Test the Integration
-
Run the following command:
/usr/bin/bigpanda-notification --send-test
A test alert should arrive in a few moments.
-
In BigPanda, click the Incidents tab at the top of the screen.
-
Confirm that the test alert was received.
-
Since it's a test alert, it won't be resolved automatically. Click Resolve incident to manually resolve it.
Success
The next time Nagios sends a notification for an alert, you will see the alert in the Incident Dashboard.
