Monitoring tools are software applications designed to track and analyze the performance of systems, networks, or applications. They help organizations ensure that their technology operates efficiently by providing real-time data on various metrics, such as uptime, response times, and resource usage. This information allows IT teams to identify issues quickly and maintain optimal performance. These tools can also generate reports and alerts, enabling proactive management of potential problems before they escalate. Common examples of monitoring tools include Nagios, Zabbix, and Prometheus, which are widely used in IT environments to enhance reliability and improve user experience.
