Note Adding permissions

# chown Nagios.nagios check_mongodb.py# chmod a+x check_mongodb.py

Third: Test whether the check_mongdb.py plug-in can be used.

#./check_mongodb.py--help

If the normal practical help option is available, the plug-in will work properly. If no module named Pymongo information is displayed, install the Pymongo module for the system.

Four: Download and install Pymongo.

Download the latest pymongo2.7.1

# wget--no-check-certificate https://pypi.python.org/packages/source/p/pymongo/pymongo-2.7.1.tar.gz

Installing Pymongo

# tar-zxvf pymongo-2.7.1.tar.gz# cd pymongo-2.7.1# python setup.py install

V: Test the MongoDB connection using the check_mongodb.py plugin.

Six: Configure Nagios.

Configuration commands

# vi /usr/local/nagios/etc/objects/commands.cfg##### #check_mongodb ####### #define  command {     command_name    check_mongodb    command_line      $USER 1$/check_mongodb.py -h  $ARG 1$ -a  $ARG 2$ -p  $ARG 3$  -W  $ARG 4$ -c  $ARG 5$ }define command {    command_name     check_mongodb_database    command_line    $ user1$/check_mongodb.py -h  $ARG 1$ -a  $ARG 2$ -p  $ARG 3$ -w  $ARG 4$ - c  $ARG 5$ -d  $ARG 6$}define command {    command_name     check_mongodb_collection    command_line     $USER 1$/check_ mongodb.py -h  $ARG 1$ -a  $ARG 2$ -p  $ARG 3$ -w  $ARG 4$ -c  $ARG 5$  -d  $ARG 6$ -c  $ARG 7$}define command {    command_name     check_mongodb_replicaset    command_line     $USER 1$/check_mongodb.py  -H  $ARG 1$ -a  $ARG 2$ -p  $ARG 3$ -w  $ARG 4$ -c  $ARG 5$ -r   $ARG 6$}define command {    command_name    check_ mongodb_query    command_line     $USER 1$/check_mongodb.py -h   $ARG 1$ -a  $ARG 2$ -p  $ARG 3$ -w  $ARG 4$ -c  $ARG 5$ -q $ arg6$}

  Configuration Services (the following separately monitor connections, idle connections, memory usage, replica set status, library size)

# vi /usr/local/nagios/etc/objects/localhost.cfg##### #check_mongodb ######### #define  service{         use                               linux-service                 host_name                        10.0.1.103         service_description             check_ mongodb_connect_54        check_command             check_mongodb!10.0.1.54!connect!27017!2!4         }  define service{        use                               linux-service         ; name  of service template to use        host_name                         10.0.1.103        service_description              check_mongodb_connections_54         check_command                    check_mongodb!10.0.1.54!connections!27017!70 !80        }define service{        use                               linux-service          ; Name of service template to use         host_name                        10.0.1.103         service_description              check_mongodb_memory_54        check_command                    check_mongodb! 10.0.1.54!memory!27017!20!28        }define service{         use                              linux-service          ; Name of service template to use         host_name                        10.0.1.103         service_description              check_mongodb_rep_state_54        check_command                     check_mongodb!10.0.1.54!replset_state!27017!0!0}define service{        use                               linux-service         ;  Name of service template to use         host_name                        10.0.1.103        service_ Description             check_mongodb_ database_exam_54        check_command                    check_mongodb_database! 10.0.1.54!database_size!27017!300!500!exam} 

Seven: Test syntax reread Nagios configuration

#/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg

If there is no error rereading the configuration

# service Nagios Reload

Eight: Check the Nagios monitoring page for verification results.
