This article mainly introduces the configuration of zabbix monitoring mongodb.

Zabbix monitoring mongodb needs to be monitored by a custom script, which can pass in multiple parameters.

Principle: through the mongodb client connection command, filter out the information output by db.serverStatus ().

First, create a monitoring data collection script

1. Content of the script:

# cat checkboxes mongodb.shatter raceme # mongodb status# db.serverStatus (). Ok# memory status# Physical memory: db.serverStatus (). Mem.resident# Virtual memory: db.serverStatus (). Mem.virtual# opcounters status# insert: db.serverStatus (). Opcounters.insert# query: db.serverStatus (). Opcounters.query# update: db.serverStatus (). Opcounters.update# delete: db.serverStatus (). Opcounters.delete# connections status# current connections: db.serverStatus (). Connections. CurrentMONGODBPATH= "/ usr/local/mongodb3.2.1/bin/mongo" HOST= "127.0.0.1" PORT= "$1" MONGODB_PA= "$MONGODBPATH ${HOST}: ${PORT}" if [$# = = 3] Then result=$ (/ bin/echo "db.serverStatus (). $2.room3" | $MONGODBPATH ${HOST}: ${PORT}-- quiet) echo $resultelif [$# = = 2]; then result=$ (/ bin/echo "db.serverStatus (). $2" | $MONGODBPATH ${HOST}: ${PORT}-- quiet) echo $resultelse echo "Usage:$0 PORT mem resident" fi

two。 Script usage

Storage location: / usr/local/zabbix/etc/scripts

Features:

(1)。 The script can accept three parameters to monitor mongodb memory usage, number of client connections, dml operation statements, etc.

(2)。 The script can accept two parameters and monitor whether the mongodb is online.

Second, modify the agent configuration file

1. Modify zabbix_agentd.conf

Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/

two。 Define the key for monitoring mongodb under zabbix_agentd.conf.d

# cat mongodb_stats.confUserParameter=mongodb_stats [*], / usr/local/zabbix/etc/scripts/check_mongodb.sh $1 $2 $3

3. Restart the agent service

Create monitoring items in the web interface

The port of mongodb instance is defined as a host macro. For more information on macro operation, please see http://hnr520.blog.51cto.com/4484939/1852655.

1. Create an items to monitor whether the mongodb is online

Key value: mongodb_stats [{$MONGODB_PORT_TEST}, ok]

two。 Create an itmes to monitor mongodb memory usage

Key value: mongodb_stats [{$MONGODB_PORT_TEST}, mem,resident]

Note: the unit of data collected is MB, and the unit is B, so you need to define a multiple of 1024 times. Otherwise, the GB cannot be displayed when the memory usage exceeds GB.

3. Create a monitoring mongodb client connection count items

Key value: mongodb_stats [{$MONGODB_PORT_TEST}, connections,current]

4. Create monitoring dml statement related information items

Key value: mongodb_stats [{$MONGODB_PORT_TEST}, opcounters,insert]

Note: it is monitored through db.serverStatus () .opcounters that the data is the total quantity since the service was started, so the stored value type needs to be modified to a difference.

Several other query, delete, and update types are created

Fourth, view the data

Select monitoring-> latest data-> Select the appropriate filter conditions

5. Create mongodb opcounters information graphics

Select configuration-> hosts-> Select mongodb hosts-> Graphics
