Prerequisites

To complete the "Monitoring Ruby on Rails with Zabbix" tutorial, you will need the following prerequisites:

• A server or virtual machine running Ubuntu 18.04 or later
• A Ruby on Rails application running on the server
• Basic knowledge of Ruby on Rails and Linux command line
• Access to the server via SSH
• A web browser to access the Zabbix web interface
• Administrative access to the server to install and configure Zabbix
• Zabbix server and Zabbix agent installed on the server
• Zabbix web interface installed and configured on the server
• A Zabbix user account with administrative privileges to configure monitoring and alerts.

Ruby on Rails Zabbix step by step setup and configuration

Integrating Zabbix into a Ruby on Rails project involves several steps. First, you need to install and configure the Zabbix agent on the server where your Ruby on Rails application is running. This will allow Zabbix to collect performance data from your application. To install the Zabbix agent on Ubuntu, you can use the following command:

sudo apt-get install zabbix-agent

Next, you need to configure the Zabbix agent to monitor your Ruby on Rails application. This involves adding a new item to the Zabbix agent configuration file that specifies the path to your application's log file. For example, if your application's log file is located at /var/log/myapp.log, you can add the following item to the Zabbix agent configuration file:

UserParameter=myapp.log[*],tail -n1 /var/log/myapp.log | awk '{print $NF}'

This item will monitor the last line of the log file and extract the last field, which is assumed to be a numeric value representing the performance metric you want to monitor.

Once the Zabbix agent is configured, you can create a new host in the Zabbix web interface and associate it with the agent. You can then create a new item for the host that specifies the key of the item you added to the agent configuration file. For example, if you added the item myapp.log[*] to the agent configuration file, you can create a new item in Zabbix with the key myapp.log[*].

Finally, you can create a new trigger in Zabbix that specifies the conditions under which an alert should be generated. For example, you can create a trigger that generates an alert if the value of the myapp.log[*] item exceeds a certain threshold. You can then configure the trigger to send an email or other notification when it is triggered.

Overall, integrating Zabbix into a Ruby on Rails project involves installing and configuring the Zabbix agent, creating a new host and item in the Zabbix web interface, and configuring a trigger to generate alerts when performance metrics exceed certain thresholds. With these steps completed, you can monitor your Ruby on Rails application and quickly identify and resolve any performance issues that arise.

Zabbix configuration options in Ruby on Rails

Here are the Zabbix configuration options for Ruby on Rails integration along with their short explanations:

• Zabbix agent: The Zabbix agent is a small program that runs on the server where your Ruby on Rails application is hosted. It collects performance data from your application and sends it to the Zabbix server for analysis.
• Zabbix server: The Zabbix server is the central component of the Zabbix monitoring system. It receives performance data from the Zabbix agent and stores it in a database. It also generates alerts and notifications based on predefined triggers.
• Zabbix web interface: The Zabbix web interface is a graphical user interface that allows you to configure and manage the Zabbix monitoring system. It provides real-time monitoring, reporting, and visualization of performance data.
• Zabbix item: A Zabbix item is a specific performance metric that you want to monitor. For example, you might create a Zabbix item to monitor the CPU usage of your Ruby on Rails application.
• Zabbix trigger: A Zabbix trigger is a predefined condition that generates an alert or notification when a performance metric exceeds a certain threshold. For example, you might create a Zabbix trigger to generate an alert when the CPU usage of your Ruby on Rails application exceeds 80%.
• Zabbix action: A Zabbix action is a predefined response to a trigger. For example, you might create a Zabbix action to send an email notification when a trigger is activated.
• Zabbix template: A Zabbix template is a predefined set of items, triggers, and actions that can be applied to multiple hosts. For example, you might create a Zabbix template for monitoring Ruby on Rails applications that includes items for CPU usage, memory usage, and disk space.
• Zabbix host: A Zabbix host is a specific server or device that is being monitored. For example, you might create a Zabbix host for your Ruby on Rails application server and associate it with a template that includes predefined items, triggers, and actions.

Conclusion

In conclusion, monitoring your Ruby on Rails application with Zabbix is a powerful way to ensure that your application is running smoothly and efficiently. With Zabbix, you can monitor key performance metrics such as CPU usage, memory usage, disk space, and network traffic, and quickly identify and resolve any issues that arise.
