Description: A monitoring tool is software used to observe and analyze system performance, allowing system administrators and developers to identify issues, optimize resources, and ensure service availability. These tools collect real-time data on various aspects of the system, such as CPU usage, memory, storage, and network, and present this information visually through graphs and dashboards. Monitoring tools are essential in various environments as they help prevent failures and maintain optimal performance. Additionally, they may include alerts that notify users of abnormal conditions or critical thresholds, facilitating a quick response to incidents. In the context of modern systems and architectures, monitoring tools are crucial for managing resources and ensuring that services communicate efficiently and securely.
