Name

• system.load.1

• The average system load over one minute.

• system.load.15

• The average system load over fifteen minutes.

• system.load.5

• The average system load over five minutes.

• system.load.norm.1

• The average system load over one minute normalized by the number of CPUs.

• system.load.norm.15

• The average system load over fifteen minutes normalized by the number of CPUs.

• system.load.norm.5

• The average system load over five minutes normalized by the number of CPUs.

计算公式

# load = [3.98, 4.57, 3.58]
system.load.1 = load[0]
system.load.5 = load[1]
system.load.15 = load[2]
# cpuCores=`cat /proc/cpuinfo | grep "model name" | wc -l`
system.load.norm.1 = system.load.1 / cpuCores
system.load.norm.5 = system.load.5 / cpuCores
system.load.norm.15 = system.load.15 / cpuCores
