how to monitor is a linux server is up or has been rebboted

Fortunately, there are a few approaches you can consider to achieve this. One option is to leverage the monitoring capabilities provided by Foglight itself. Foglight offers various features and plugins that can be configured to monitor the status of servers and detect any reboots. By setting up the appropriate monitoring parameters and thresholds, you can receive alerts or notifications whenever a server goes offline or undergoes a reboot.

Another alternative is to utilize existing monitoring tools or scripts within your server's operating system. Most operating systems provide built-in tools or command-line utilities that can be used to check the status of servers. For example, on Linux systems, you can use commands like "ping" to check if a server is responsive, or tools like "uptime" to determine the time since the last reboot. On Windows systems, you can employ commands like "ping" or PowerShell scripts to achieve similar results.
