README

This is a simple, yet powerful Zabbix API client for PHP. I have made no attempt to model the Zabbix API in PHP functions, but rather, I have made the interface extremely easy to use in order to query the Zabbix JSON-RPC API.

There are several examples in examples/ that should be quite useful. You can even make a copy of zabbix_auth.php and call it zabbix_auth_local.php and that file will be used by the examples instead, so you don't need to taint the git repo.

Compatibility

This library is designed and tested for Zabbix 2.2 and it's likely to have problems with other versions. If you want to add support for 2.4 (or any other version) you are more than welcome :)

Authentication

Zabbix uses a username and password to connect initially, then an auth token for subsequent requests.

Here's how you connect and authenticate:

$client = new ZabbixClient(
    "http://myzabbixserver/zabbix/api_jsonrpc.php",
    "myusername",
    "mypassword"
);

Calling Zabbix Endpoints

All the Zabbix endpoints are described in the Zabbix Documentation.

To call and endpoint, use the $client->request(string endpoint, array params=[]) method:

$response = $client->request('apiinfo.version');
echo "Server is running Zabbix $response\n";

Note that $response is a kamermans\ZabbixClient\ApiResponse object that has some magical properties. In the example above, the Zabbix endpoint apiinfo.version returns a single string, so you can use $response as a string as well.

Most endpoints return an associative array as a response:

$hosts = $client->request('host.get', [
    'output' => [
        'host_id',
        'host',
    ],
]);

foreach ($hosts as $host) {
    echo "{$host['hostid']}: {$host['host']}\n";
}

As you can see, you can iterate over the response object (although it's still a kamermans\ZabbixClient\ApiResponse).

In this example we also passed an array of parameters as the second argument.

Error Handling

When the Zabbix API returns an error, it is wrapped up into a proper exception and thrown.

There are three types of exceptions that you can catch inside the kamermans\ZabbixClient namespace:

  • Exception: base class used for generic exceptions. All exceptions extend this one.
  • ApiException: all API calls that returned a parseable JSON response are wrapped by this exception which gives you a well-formed error message from Zabbix and access to raw response via ApiException::getResponse().
  • AuthException: an extention of ApiException that only gets thrown for authentication errors so they can be handled differently.

Utility Functions

Response Dumping

For easy troubleshooting of responses, you can use the ApiResponse::dump() function to output the response to the screen, or ApiResponse::dd() to dump and die:

$response = $client->request('apiinfo.version');
$response->dd(); // '2.2.8'

Server Ping

There is a utility function to check to latency (in milliseconds) to the Zabbix Server API:

$time = $client->ping();
echo "Pinged Zabbix Server in {$time}ms\n";

Complete Example

This example lists all the system items in the Zabbix Server:

<?php

require __DIR__.'/../vendor/autoload.php';

use kamermans\ZabbixClient\ZabbixClient;

$client = new ZabbixClient(
    "http://myzabbixserver/zabbix/api_jsonrpc.php",
    "myusername",
    "mypassword"
);

$host = 'Zabbix server';
$key = 'system';

echo "Showing $key items for $host\n\n";

$response = $client->request('item.get', [
    'host' => $host,
    'search' => [
        'key_' => $key,
    ],
    'sortfield' => 'name',
]);

foreach ($response as $item) {
    echo "{$item['name']}: {$item['lastvalue']}\n";
}

Output:
