***** Nagios *****
Notification Type: PROBLEM

Service: MEM_USE
Host: s3
Address: 10.10.10.10
State: UNKNOWN

Date/Time: Tue Jun 28 17:41:42 CST 2016

Unable to determine memory usage.

解决过程：

1、根据Service：MEM_USE在文件/etc/nagios/objects/hosts/s3.cfg中找到相应配置

define service{

use generic-service ; Name of service template to use

host_name s3

service_description MEM_USE

check_command check_nrpe!check_mem_used

notifications_enabled 1

contact_groups admins,dxgroup

}

2、在s3上执行检查命令

[root@s3 ~]# /usr/local/nagios/libexec/check_mem.sh 85 90

/usr/local/nagios/libexec/check_mem.sh: line 57: /usr/bin/bc: 没有那个文件或目录

/usr/local/nagios/libexec/check_mem.sh: line 58: /usr/bin/bc: 没有那个文件或目录

/usr/local/nagios/libexec/check_mem.sh: line 69: bc: command not found

/usr/local/nagios/libexec/check_mem.sh: line 69: [: -eq: unary operator expected

/usr/local/nagios/libexec/check_mem.sh: line 72: bc: command not found

/usr/local/nagios/libexec/check_mem.sh: line 72: [: -eq: unary operator expected

/usr/local/nagios/libexec/check_mem.sh: line 75: bc: command not found

/usr/local/nagios/libexec/check_mem.sh: line 75: [: -eq: unary operator expected

Unable to determine memory usage.

3、按照第2步骤提示没有安装bc，安装bc

[root@s3 ~]# yum -y install bc
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* base: mirrors.yun-idc.com
* extras: mirror.bit.edu.cn
* updates: mirrors.yun-idc.com

4、安装完成后，再次执行

[root@s3 ~]# /usr/local/nagios/libexec/check_mem.sh 85 90
OK - Memory usage is 2.200%
