What intervals does the uptime command show usage statistics for?

The uptime command in Linux provides information about how long the system has been running, as well as the average load on the system over specific time intervals. The correct answer shows that the uptime command provides load averages for the last 1 minute, 5 minutes, and 15 minutes.

These load averages represent the number of processes that are in a runnable state, waiting to be executed by the CPU. By assessing these intervals, system administrators can gauge the system's performance and responsiveness. A high load average could indicate that the system is becoming overloaded, particularly if the values exceed the number of processing cores on the machine.

In summary, the command outputs average load values for the last 1, 5, and 15 minutes, which is critical information for monitoring the health and performance of a Linux system.
