点击(此处)折叠或打开

  1. 4 Hours
  2. 24 Hours
  3. One Week
  4. One Month
  5. One Year
  6. vi /usr/local/nagios/etc/pnp/config.php

  8. $views[0]["title"] = "4 Hours";
  9. $views[0]["start"] = ( 60*60*4 );
  10. $views[1]["title"] = "24 Hours";
  11. $views[1]["start"] = ( 60*60*24 );
  12. ###更改为
  13. $views[0]["title"] = "30 Minutes";

  10. command_line /usr/lib64/nagios/plugins/pmp-check-mysql-innodb -H 127.0.0.1 -l root -p admin
  11. }
  12. define command{

  14. command_line /usr/lib64/nagios/plugins/pmp-check-mysql-deleted-files -H 127.0.0.1 -l root -p admin
  15. }

5、

点击(此处)折叠或打开

  1. vi /usr/local/nagios/etc/localhost.cfg
  2. 添加
  3. define service {
  4. use local-service
  5. host_name localhost
  6. service_description Mysql Processlist
  7. check_command mysql_process!16!32
  8. }
  9. define service {
  10. use local-service
  11. host_name localhost
  12. service_description Mysql Innodb
  13. check_command mysql_innodb!3!10
  14. }

以上只添加了3个针对mysql的监控,可根据实际需要继续添加。
某些mysql监控脚本中的命令需要root权限,根据监控提示可对脚本作出一定更改
