PhpMonit

Small Monitoring system write in PHP (Just to monitor some hosts, not a lot)

It can check on Unix host :

• Uptime
• Load Usage
• Memory Usage
• Swap Usage
• Disk Usage
• Disk Inode Usage

And for all type of host :

• Ping from current server
• Open ports on the host

Installation

Copy source into a directory : cd /home/http/PhpMonit

Use Composer to install PHP libraries : composer.phar install

Prepare configuration : cp data/server.php.sample data/server.php

Edit Configuration : vim data/server.php

Add script/test_all.php in crontab (start it each 5 mins)

Configuration

The configuration is stored in a PHP Array. Each item of the main array define a host to check.

$arServers = [
    'server name' => [
        'host' => 'hostname',
        'type' => 'HostUnix', // The only suported host type
        'ssh' => [ // SSH info to connect to the server (ssh key only)
            'login'       => 'monitor',  
            'private_key' => 'data/deploy_rsa',
            'public_key'  => 'data/deploy_rsa.pub',
        ],
        'services' => [ // list of activated services
            'uptime' => ['minimal' => 3600],
            'load' => ['maximal' => [1.5, 1, 1]],
            'mem' => ['mem_minimal' => '10', 'swap_minimal' => '95', 'need_swap' => false],
            'disk' => [mounts=> ['/'], params => ['minimal' => 10]],
            'diskInode' => [mounts=> ['/'], params => ['minimal' => 10]],
            'port' => ['list' => [22, 25, 80, 443], 'needed' => [22, 80, 443]],
        ],
    ]
];
