How to add new host (zabbix agent) at Zabbix Server

Step 1 – Configuration ==> Hosts ==> Create Host

Step 2 – Enter Follwing

- Host name - 
- Templates - Linux by Zabbix Agent OR Windows by Zabbix agent
- Groups - Virtual Machine
- Interfaces - Agent

Note - Use Public IP address of Agent
Code language: PHP (php)

Step 3 – Wait for 60 seconds and verify as below;

The Availability column contains indicators of host availability per each interface. We have defined a Zabbix agent interface, so we can use the agent availability icon (with ‘ZBX’ on it) to understand host availability:

•  – host status has not been established; no metric check has happened yet
•  – host is available, a metric check has been successful
•  – host is unavailable, a metric check has failed (move your mouse cursor over the icon to see the error message). There might be some error with communication, possibly caused by incorrect interface credentials. Check that Zabbix server is running, and try refreshing the page later as well.

How to configure and deploy Zabbix passive and active agents:

1. Install the Zabbix repository and the Zabbix Agent on your host
2. Open the zabbix_agentd.conf configuration file
3. Specify your Zabbix Server address in the Server and ServerActive parameters
4. Define the name of your host in the Hostname parameter
5. Restart the Zabbix Agent
6. Navigate to Configuration →  Hosts
7. Create two hosts in Zabbix frontend – one for passive and one for active checks
8. For passive Agent host – define an Agent interface containing the address of your Zabbix Server
9. The active agent Host name should match the Hostname parameter value in the Agent configuration file
10. Apply the corresponding Linux by Zabbix Agent/Linux by Zabbix Agent active template
11. Navigate to Monitoring →  Latest data and check if you have received metrics from the hosts
