For Performance Gauges to show details properly, performance data should be in following format: 'VarName'=CurrentValue Unit;WarningValue;CriticalValue;MininumValue;MaximumValue Important: 1. It uses the output of 'sar' command. 2. Warning and Critical thresholds are 80% and 90% for %user, %system, % nice, %iowait and %steal time. 3. Warning and Critical thresholds for %idle time makes no sense. How To Use: To monitor remote Linux server: 1. Keep the plugin in /usr/local/nagios/libexec directory. 2. Add following line to the nrpe.cfg file: command[check_cputime.sh]=sudo /usr/local/nagios/libexec/check_cputime.sh 3. Add the following line to /etc/sudoers file: nagios ALL=(ALL) NOPASSWD:/usr/local/nagios/libexec/check_cputime.sh Usage: On Monitoring Server: ./check_nrpe -H 128.9.45.13 -c check_cputime.sh Output: OK- %user=8.03%, %nice=0.00%, %system=21.07%, %iowait=0.00%, %steal=0.00%, %idle=70.90% | '%user'=8.03%;80;90;0;100 '%nice'=0.00%;80;90;0;100 '%system'=21.07%;80;90;0;100 '%iowait'=0.00%;80;90;0;100 '%steal'=0.00%;80;90;0;100 %idle=70.90%;;;0;100
