PackageHeader.png

This Laravel package allows you to run SNMP queries to the snmp-agent of network hosts through laravel applications.

Before you run any SNMP query in your Laravel application, you must install snmp in the operating system and enable the PHP extension ext-php in the php.ini to make queries.

Installation

Requirements

At the Operating System level, you need to install net-snmp.

Debian

apt-get install -y snmp

Centos / RHEL

yum install \
  net-snmp.x86_64 \
  net-snmp-agent-libs.x86_64 \
  net-snmp-libs.x86_64 \
  php-snmp.x86_64

At php.ini enable the extension ext-php.

Composer Install

You can install the package via composer:

composer require acamposm/snmp-poller

Publish vendor assets

Running this command, you can publish the vendor assets. This allows to modify the default package configuration.

php artisan snmp:install

Usage

Single SNMP Poller class

use Acamposm\SnmpPoller\SnmpPoller;
use Acamposm\SnmpPoller\Pollers\IfTablePoller;
use SNMP;

$session = new SNMP(SNMP::VERSION_2C, '192.168.10.254', 'csnmpv2c');

$poller = new SnmpPoller();

$poller->setSnmpSession($session)->addPoller(IfTablePoller::class)->run();

The output of an SNMP query to the snmp-agent of a network host with a single SNMP Poller class returns an array of objects with the data inside the data field.

Note: For demonstration purposes, all ports between 3 and 22 have been removed from the output of the query.

Multiple SNMP Pollers classes

use Acamposm\SnmpPoller\SnmpPoller;
use Acamposm\SnmpPoller\Pollers\IfTablePoller;
use Acamposm\SnmpPoller\Pollers\IfExtendedTablePoller;
use Acamposm\SnmpPoller\Pollers\EntPhysicalTablePoller;

use SNMP;

$session = new SNMP(SNMP::VERSION_2C, '192.168.10.254', 'csnmpv2c');

$poller = new SnmpPoller();

$pollerClasses = [
   IfTablePoller::class,
   IfExtendedTablePoller::class,

   LldpRemoteTablePoller::class,
];

$poller->setSnmpSession($session)
       ->addPollers($pollerClasses)

The output of an SNMP query to the snmp-agent of a network host with multiple SNMP Poller classes returns an array of objects with the data inside the data field.

Note: For demonstration purposes, all ports between 3 and 22 have been removed from the output of the query.
