In Linux, to see the system load for 1 minutes, 5 minutes, and 15 minutes, you can use the Uptime command:The third item: the average number of processes running in the queue within 15 minutes is a reference, mainly in two ways: from 1 minutes-

Cat 192.168.101.* | grep Load | awk ' {sum+=$4} END {print ' average= ', sum/nr} 'Cat 192.168.101.* | grep Memory | awk ' {sum+=$3} END {print ' average= ', sum/nr} 'Cat 192.168.101.* | grep Os-root | awk ' {sum+=$5} END {print ' average= ', sum/nr}

Purpose Description The uptime command is used to display system Run-time information (tell-how long, system has been running.), and the following is an example and description of the output information: 21:41:43 up 2 days, 12:28, 7 users, load

In the analysis of the system, one of the first and most basic tools is often a simple measurement of the CPU utilization of the system. Linux and most unix-based operating systems provide a command to display the system's average load (loadaverage).

load Average (average load) Basic concepts: load refers to the length of the run queue (run-queue) : L = number of waiting processes + number of running processes Load Average A statistic that refers to the sum of the number of processes that
