icinga check_nrpe 报错收集

一、安装nrpe，编译的时候提示以下信息

• checking for SSL headers... configure: error: Cannot find ssl headers
• 原因是缺少openssl-devel包，解决办法
• CentOS
  • yum -y install openssl-devel
• debian
• apt-get install libssl-dev

二、服务器端和客户端的nrpe版本必须一致才能正确采集数据，报错如下

• CHECK_NRPE: Socket timeout after 10 seconds
• Connection refused or timed out

三、nrpe参数传递错误

• CHECK_NRPE: Received 0 bytes from daemon. Check the remote server logs for error messages.
• 重新编译nrpe
• CentOS
  • ./configure --prefix=/usr/local/icinga --enable-ssl --with-nrpe-user=nagios --with-nrpe-group=nagios --with-nagios-user=nagios --with-nagios-group=nagios --enable-command-args

• Debian

  • ./configure --prefix=/usr/local/icinga --enable-ssl --with-nrpe-user=nagios --with-nrpe-group=nagios --with-nagios-user=nagios --with-nagios-group=nagios --enable-command-args --with-ssl-lib=/usr/lib/x86_64-linux-gnu

• 测试
  /usr/local/icinga/libexec/check_nrpe -H x.x.x.x -c check_disk_args -a 4% 11% data

四、check_icmp check_dhcp 权限问题

• 由于对 icinga/libexec 执行了chown nagios.nagios . -R出现如下错误
  Warning: This plugin must be either run as root or setuid root.
• 解决办法
  chown root.nagios check_icmp
chown root.nagios check_dhcp chmod 4750 check_icmp
chmod 4750 check_dhcp
