What are the best options for monitoring Amazon cloud servers, other than CloudWatch?

Monitoring Amazon cloud servers beyond CloudWatch can be achieved through various robust solutions. Prometheus, an open-source tool, excels in collecting and querying metrics, offering flexibility. Grafana, when paired with Prometheus, provides insightful visualizations for performance analysis. Datadog stands out for its comprehensive monitoring, alerting, and collaboration features, supporting multi-cloud environments. New Relic offers deep insights into application performance with its APM capabilities. Zabbix, another open-source option, provides extensive monitoring and alerting capabilities. Each of these alternatives brings unique strengths, catering to diverse monitoring needs beyond CloudWatch, ensuring a well-rounded approach to overseeing Amazon cloud server performance.
