在nagios上安装mongodb_check监控mongodb

1.安装check_mongodb.py
yum install git
cd /usr/local/nagios/libexec/
wget --no-check-certificate https://github.com/mzupan/nagios-plugin-mongodb/archive/master.zip
unzip master 
mv nagios-plugin-mongodb-master nagios-plugin-mongodb
chown -R nagios.nagios nagios-plugin-mongodb/

2. 安装Mongo Python驱动
下载：https://bitbucket.org/pypa/setuptools/get/default.tar.gz#egg=setuptools-dev
tar -xvf pypa-setuptools-5c8ce4511aa5.tar.gz
cd pypa-setuptools-5c8ce4511aa5
python setup install

安装pymongo
git clone git://github.com/mongodb/mongo-python-driver.git pymongo
cd pymongo/
python setup.py install
或者：
wget --no-check-certificate https://github.com/mongodb/mongo-python-driver/archive/master.zip
unzip master.zip
cd mongo-python-driver-master
python setup.py install


3. 测试驱动安装：

define command {
        command_name    check_mongodb
        command_line    /etc/nagios/command/nagios-plugin-mongodb/check_mongodb.py -H $HOSTADDRESS$ -A $ARG1$ -P $ARG2$ -W $ARG3$ -C $ARG4$
        }
5 加入mongo监控的配置
vi hosts.cfg
define service{
        use                             local-service         ; Name of service template to use
        host_name                       Mongodb-Linux

        notifications_enabled           1
        }
       
6. 检查配置
./bin/nagios -v ./etc/nagios.cfg 
7.重启nagios reload
service nagios restart
