Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References: Event logs are the primary source for tracking server reboots and other system events. Logs such as the system log in Linux (/var/log/syslog or /var/log/messages) or the Event Viewer in Windows provide timestamps and details about shutdowns, restarts, and boot processes. Regular monitoring ensures that unplanned reboots or system errors are identified and addressed. * Uptime: Indicates how long the server has been running since the last reboot but does not provide detailed reboot evidence. * IOPS: Refers to input/output operations per second, unrelated to reboots. * CPU utilization: Reflects processor activity but offers no reboot evidence.
