Project Notes
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 'uptime' command. 2. Warning and Critical thresholds are 80% and 90% of the total number of processor cores. For Ex: If you are using 16 core processor, Warning threshold will be 80% of 16 i.e. '12.8' and Critical threshold will be 90% of 16 i.e. '14.4' 3. If the calculated value, may it be 1 min load, 5 min load or 15 min load, exceeds the thresholds, status will be set accordingly (OK, WARNING or CRITICAL). 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_loadaverage.sh]=sudo /usr/local/nagios/libexec/check_loadaverage.sh 3. Add the following line to /etc/sudoers file: nagios ALL=(ALL) NOPASSWD:/usr/local/nagios/libexec/check_loadaverage.sh Usage: On Monitoring Server: ./check_nrpe -H 128.9.45.13 -c check_loadavg.sh Output: OK- Load Average: 0.09, 0.05, 0.01 | load1=0.09;6.4;7.2;; load5=0.05;6.4;7.2;; load15=0.01;6.4;7.2;;
