第二部分关于nrpe的安装
#!/bin/bash #INSTALL NRPE DAEMON# src=/home/nagios/src nagios_home=/home/nagios/nagios yum install openssl openssl-devel useradd nagios groupadd nagcmd usermod -a -G nagcmd nagios echo "5cr8xOW7DF"|passwd --stdin nagios su - nagios mkdir ${src} cd ${src} wget http://nagios-plugins.org/download/nagios-plugins-2.0.tar.gz wget http://jaist.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz echo "##INSTALL NAGIOS-PLUGINS##" tar xvf nagios-plugins-2.0.tar.gz cd nagios-plugins-2.0 ./configure --prefix=${nagios_home} --enable-perl-modules make && make install cd ${src} echo "##INSTALL NRPE##" tar xvf nrpe-2.15.tar.gz cd nrpe-2.15 #编译启用参数传递 ./configure --prefix=${nagios_home} --with-nrpe-user=nagios --with-nrpe-group=nagios --enable-command-args make all make install-plugin make install-daemon make install-daemon-config exit cd ${src}/nrpe-2.15/ make install-xinetd sed -i 's/127.0.0.1/192.168.28.241/g' /etc/xinetd.d/nrpe echo "nrpe 5666/tcp # NRPE" >>/etc/services chown nagios. /etc/xinetd.d/nrpe service xinetd restart lsof -i:5666
nrpe.cfg配置文件简单如下
log_facility=daemon pid_file=/var/run/nrpe.pid server_port=5666 server_address=127.0.0.1 nrpe_user=nagios nrpe_group=nagios allowed_hosts=127.0.0.1 dont_blame_nrpe=1 allow_bash_command_substitution=0 debug=0 command_timeout=60 connection_timeout=300 command[check_users]=/home/nagios/nagios//libexec/check_users -w $ARG1$ -c $ARG2$ command[check_load]=/home/nagios/nagios//libexec/check_load -w $ARG1$ -c $ARG2$ command[check_disk]=/home/nagios/nagios//libexec/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$ command[check_procs]=/home/nagios/nagios//libexec/check_procs -w $ARG1$ -c $ARG2$ -s $ARG3$
其中server_address/allow_address注意根据实际修改,dont_blame_nrpe=1(默认为0,1为开启参数传递)
nagios server端command.cfg需另外define一个check_remote_nrpe的command
define command{ command_name check_remote_nrpe command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$ $ARG3$ $ARG4$ }
这样监控服务,如客户端环境改变需调整参数的话只需要在nagios服务端修改参数即可,例如
define service{ use linux-service hostgroup_name 97f5eafb7a service_description check partition / check_command check_remote_nrpe!check_disk!20%!10%!/ }
第三部分,如果以后添加新监控点,则需去修改每台客户机的nrpe.cfg文件去define command,这样太麻烦了。所以再添加这样一个脚本来传递整个命令,客户端如需添加新监控点只需上传监控脚本,nagios服务端define service即可
#!/bin/sh while getopts "a:c:" arg do case $arg in a) arg_a=$OPTARG; ;; c) arg_c=$OPTARG; ;; ?) echo "unkonw argument" echo "only -c -a argument" exit 1 ;; esac done if [[ "$arg_c" =~ "$HOME/" ]];then if [ ! -x $arg_c ];then echo "[$arg_c] not execute"; exit 3; fi $arg_c $arg_a; exit $?; else echo "cannt execute $arg_c,not allow execute [$HOME] outside scripts"; exit 3; fi
nagios的command文件需添加如下
define command{ command_name check_nrpe_exec command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a $ARG2$ }
客户端nrpe.cfg配置文件command部分只需要有
command[exec_command]=/home/nagios/nagios//libexec/exec_command -c exec_command -a "$ARG1$"
添加监控点例子,只需修改exec_command后的监控脚本命令
define service{ use linux-service host_name 887a34d257 service_description check_swap check_command check_nrpe_exec!"/home/nagios/nagios/libexec/check_swap -w 50% -c 30%" }
