13. Zabbix adding hosts in the API way

The Zabbix API begins to play an increasingly important role, especially when integrating third-party software and automating daily tasks. It's hard to imagine how difficult it is to manage thousands of servers without automation. The Zabbix API provides a programmable interface for bulk operations, third-party software integration, and other functions.

The Zabbix API was introduced in version 1.8 and has been widely used. All Zabbix mobile clients are API-based and even native web front-end parts are built on top of it. The Zabbix API middleware makes the architecture more modular and avoids direct manipulation of the database. It allows you to create, update, and retrieve Zabbix objects through the JSON RPC protocol and do whatever you like "if you have an authentication account," of course.

The Zabbix API provides two key features:

Remote Management Zabbix Configuration

Remote retrieval of configuration and historical data

Using JSON

The API is implemented with JSON-RPC. This means that any function that is called will need to send a POST request, and the input and output data are in JSON format. The approximate workflow is as follows:

Prepare the JSON object, which describes what you want to do (create a host, get an image, update a monitor item, and so on).

The Post method is used to

1. To do before the monitoring host Server3 deleted, the first step, generate Authentication Tokens

• "Jsonrpc": "2.0"-this is the standard JSON RPC parameter to indicate the protocol version. All requests will remain unchanged.

• "Method": "User.login"-This parameter defines the action that is actually performed. For example: Host.create, item.update, etc.

• "Params"-this is done by passing a JSON object as a parameter to a particular method. If you want to create a monitoring entry, the "name" and "Key_" parameters are required, and the parameters required for each method are described in the Zabbix API documentation.

• "id": 1-this field is used to bind JSON requests and responses. The response will have the same "id" as the request. Useful when sending multiple requests at once, and these do not require a single or sequential

• "Auth": "*********************"-This is an authentication token "authentication token" to authenticate the user and access the API. This is also the premise of using the API for related operations-get the authentication ID.

Note: Write the command into the shell script
