Infrastructure monitoring provides comprehensive and proactive alerts

One of the valuable features of this site is that it operates 24/7, monitoring my entire infrastructure, uptime, and related error issues. For example, it can monitor my network switches. The feature includes IP SLA to assess IP-based connections like static IPs. An alert is generated if issues occur, monitored through email notifications. It can also monitor Kubernetes, containers, FTP servers, and MSP features. The self-healing automation capability is also included.

"The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want."

"The most valuable features are the reports and the way it generates the report in a graphical manner."
