nagios monitor mongodb resolves Nagios interface display null issue

There are many online The introduction of Nagios monitoring MongoDB , but without exception, manual execution python can get the value of the client,the Nagios monitoring interface shown above NULL, for this issue, I have re-encapsulated some of the monitoring options with shell scripts, allowing Nagios to monitor the MongoDB server properly

If you would like to know about the deployment process for Nagios monitoring MongoDB, please click:

Https://github.com/mzupan/nagios-plugin-mongodb/blob/master/README.md

Implementation principle:

Use a shell script to get the value of check_mongodb.py and then pass it to Nagios to implement Nagios warnings

currently check_mongodb.sh just configure the ' Connect ' ' Connections ' replset_state ' memory ' option

can refer to README.MD the configuration!

Test Configuration:

Run a command under the Nagios account to check the mongodb server: ( executed under Nagios account)
