Have you used any infrastructure monitoring tools like Nagios, Zabbix, or Datadog? Explain your experience with monitoring system health and performance

Yes, I've used monitoring tools like Nagios and Datadog for monitoring system health and performance. These tools provided real-time visibility into the health and performance of infrastructure components, including servers, networks, and applications. I've configured alerts and thresholds to proactively identify and respond to issues before they impact the user experience. Performance metrics were analyzed to optimize resource utilization and ensure optimal system performance.
