Execute Python Script on Remote Linux Host with Zabbix Agent
Video Lecture
Description
I create a Python script on my remote Linux host that prints a random number.
I create a new item for the host and select the system.run option for the key and enter the Python command needed to run the new .py file on the remote host.
Create the Python Script
Create a folder on the remote Linux host. (if the folder doesn't already exist)
mkdir /home/zabbix/
CD into the folder
cd /home/zabbix
Create the Python script
sudo nano genrand.py
Paste in the following
1 2 | |
Save and test
python3 genrand.py
You should see a random integer from 0 to 36.
Configure Item in Zabbix UI
Now in the Zabbix UI, add a new item to your host configuration,
| Key | Value |
|---|---|
| Name | Generate Random Number |
| Type | Zabbix agent |
| Key | system.run[python3 /home/zabbix/genrand.py] |
| Type of information | Numeric (Or Text if you want to see the error message in the latest data) |
And then try using the Test button at the bottom of the form.
It is unlikely to work until you've configured the DenyKey and AllowKey in the Zabbix agents configuration.
Zabbix Agent Configuration
Edit the Zabbix agents configuration file
sudo nano /etc/zabbix/zabbix_agentd.conf
I have explicitly allowed this key by adding,
AllowKey=system.run[python3 /home/zabbix/genrand.py]
After making changes to the configuration, restart and check status
sudo service zabbix-agent restart
sudo service zabbix-agent status
No go back into the Zabbix UI and test the new item again.
