Working Criteria for MongoDB 4.0 with ReplicaSet

[eligiable]

This is a Great Script, I've done some modifications according to the following environment:

• AWS
• Ubuntu 16.04
• Zabbix Agent 3.4
• MongoDB 4
• Python3

Below are my configuration:

• Installing PyMongo
  sudo apt-get install build-essential python-dev python3-pip
sudo pip3 install pymongo
• Installing Zabbix_Sender
  sudo apt-get install zabbix-sender
• Change python to python3 in mongodb-stats.sh
  python /usr/local/bin/zabbix-mongodb.py -- to --> python3 /usr/local/bin/zabbix-mongodb.py
• Change Parameters under class MongoDB(object), in case of ReplicaSet
  self.mongo_host = "hostname"
• Provide Credentials if you have enabled Security
  self.mongo_user = "username"
self.mongo_password = "password"

Appriciate your effort ...

Hi @eligiable thanks for sharing your environment. I have a similar set up with the differences being I am using Ubuntu 18.04 and Python 2.7.15rc1

When I run python zabbix-mongodb.py I am getting all the stats and they are being written on the screen. So I am assuming that there are no issues with python versino.

But when I run sh mongodb-stats.sh

I keep getting the following error.

close failed in file object destructor:
sys.excepthook is missing
lost sys.stderr
zabbix_sender [26855]: invalid parameter "/etc/zabbix/zabbix_agentd.conf"

Looks like the issue is when the python script is being called form shell script. Any pointers to fix the issue would be great. Thanks in advance.

Hi @nkgokul just install zabbix_sender, which is not by default installed with zabbix-agent or zabbix-server.

sudo apt install zabbix_sender and then try,
