Nagios Support Forum

Good morning, I would like more information on how to monitor IT services with the Nagios Nagios application; or some manual where I can find information on how to develop the configurations

Open the Nagios app on your mobile device. Tap on the settings or configuration icon to access the app settings. Enter the necessary information to connect the app to your Nagios server, such as the server IP address, username, and password. Save the settings.
In the Nagios app settings, configure the notification preferences according to your needs. You can choose to receive push notifications, email notifications, or both when a service or host goes down or encounters issues.
After configuring the app settings, test the connectivity by tapping on the refresh or sync button within the app. This will fetch the latest status information from your Nagios server.
Once the app is connected to your Nagios server, you can start monitoring your IT services. The Nagios app will display the status of hosts and services, such as whether they are up, down, or experiencing issues. You can view detailed information, acknowledge alerts, and take appropriate actions directly from the app.

Install Nagios: Start by installing Nagios on a server or machine that will act as the monitoring host. You can download Nagios from the official Nagios website and follow the installation instructions provided in the documentation.

Define Hosts and Services: Once Nagios is installed, you need to define the hosts (devices, servers, or services) that you want to monitor. This involves configuring the necessary parameters such as IP addresses, hostnames, and connection details.

Configure Service Checks: After defining hosts, you need to specify the services you want to monitor on each host. This can include services like HTTP, FTP, SSH, SMTP, etc. Configure service checks by defining parameters such as check intervals, thresholds, and specific criteria for determining service status.

Set Up Notifications: Nagios can send notifications when a service check fails or when certain conditions are met. Configure notification settings to define who should be notified (email, SMS, etc.) and under what circumstances.

Customize Monitoring: Nagios allows for customization to meet specific monitoring requirements. You can define custom plugins, create service groups, set up dependencies, and configure advanced monitoring options based on your needs.
