Easy-to-use, but feature-rich client for Checkmk Web API

Latest Stable Version Minimum PHP Version Build Status

About

Checkmk is a software application for network monitoring. The community edition ("raw") is licensed under the GPLv2.

This client communicates with Checkmk over its Web API. It provides a simple, but powerful abstraction layer for written in PHP. Feel free to use it as a library in your own projects.

Requirements

Meet these simple requirements before using the client:

  • One or more Checkmk sites, version 1.4 or higher (most calls work since 1.5)
  • PHP, version 7.1 or higher (7.0 still works but is deprecated; 7.3 is recommended)
  • PHP modules curl, date, json, openssl, spl and zlib

Installation

It is recommended to install this client via Composer. Change to your project's root directory and fetch the latest stable version:

composer require bheisig/checkmkwebapi

This command installs the latest stable version. Instead of sticking to a specific/minimum version you may switch to the current development branch by using @DEV:

composer require "bheisig/checkmkwebapi=@DEV"

Updates

Composer has the great advantage (besides many others) that you can simply update the client by running:

composer update

Usage

Composer comes with its own autoloader. Include this line into your PHP code:

require_once 'vendor/autoload.php';

This is it. All other files will be auto-loaded on-the-fly if needed.

First call

This is a simple "Hello, world!" example. It fetches all configured hosts from Checkmk:

use bheisig\checkmkwebapi\API;
use bheisig\checkmkwebapi\Config;
use bheisig\checkmkwebapi\Host;

$config = new Config();
$config
    ->setURL('https://monitoring.example.org/mysite/check_mk/')
    ->setUsername('automation')
    ->setSecret('abc123');

$api = new API($config);

$request = new Host($api);
$hosts = $request->getAll();

var_dump($hosts);

Configuration

The API class requires configuration settings passed to its constructor:

use bheisig\checkmkwebapi\API;
use bheisig\checkmkwebapi\Config;

$config = new Config();
$config
    ->setURL('https://monitoring.example.org/mysite/check_mk/')
    ->setPort(443)
    ->setUsername('automation')
    ->setSecret('abc123')
    ->enableProxy()
    //->disableProxy()
        ->useHTTPProxy()
        //->useSOCKS5Proxy()
        ->setProxyHost('proxy.example.net')
        ->setProxyPort(8080)
        ->setProxyUsername('proxyuser')
        ->setProxyPassword('verysecure');

$api = new API($config);
