用nagios监控mongodb

网上已经有人写好了mongodb的nagios监控脚本,参考:https://github.com/mzupan/nagios-plugin-mongodb/blob/master/README.md

1) 先安装git

yum install git

2) 下载脚本

cd /etc/nagios/command

git clone git://github.com/mzupan/nagios-plugin-mongodb.git

cd nagios-plugin-mongodb/
chmod 755 check_mongodb.py

如果执行报下面的错误:

# ./check_mongodb.py –help
need to install pymongo

需要安装pymongo:

git clone git://github.com/mongodb/mongo-python-driver.git pymongo
cd pymongo/
python setup.py install

3) 修改nagios配置,加入这个命令

vi objects/commands.cfg
# ‘check_mongodb’ command definition
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 $ARG4$
        }

4) 加入mongo监控的配置

vi hosts.cfg
define service{
        use                             generic-service         ; Name of service template to use
        host_name                       monodb_host
        service_description             mongodb
        check_command                   check_mongodb!connect!27017!10!30
        notifications_enabled           1
        }
      

5) 没错的话,重载nagios就行了。

nagios -v /etc/nagios/nagios.cfg
service nagios reload
