Effective IT monitoring is essential for maintaining system health and performance. Best practices include defining clear objectives, choosing the right tools, implementing continuous monitoring, setting up alerting systems, and regularly updating strategies. For AWS monitoring, leverage AWS CloudWatch, monitor resource utilization, enable logging and auditing, implement cost monitoring, and ensure security. Agentless server monitoring, using protocols like SNMP and WMI, offers reduced overhead and security risks. Regular updates and audits enhance reliability. By following these practices, businesses can achieve seamless operations and optimize performance, with Netreo providing comprehensive monitoring solutions.
