README

Collect Linux server metrics through an existing SSH connection.

Installation

composer require jord-jd/php-server-info

Usage

<?php

use JordJD\ServerInfo\Server;
use JordJD\SSHConnection\SSHConnection;

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

$connection = (new SSHConnection())
    ->to('example.com')
    ->as('username')
    ->withPrivateKey('/home/user/.ssh/id_rsa');

$array = (new Server($connection))
    ->metrics()
    ->toArray();

var_dump($array);

array(14) {
  ["uptime"]=>
  int(7564013)
  ["hostname"]=>
  string(11) "example"
  ["disk-usage-percentage"]=>
  int(29)
  ["total-disk-space-bytes"]=>
  int(1000204886016)
  ["memory-usage-percentage"]=>
  int(37)
  ["total-memory-bytes"]=>
  int(1033347072)
  ["swap-usage-percentage"]=>
  int(26)
  ["total-swap-bytes"]=>
  int(1073737728)
  ["mysql-server-running"]=>
  bool(true)
  ["apache-server-running"]=>
  bool(false)
  ["nginx-server-running"]=>
  bool(true)
  ["active-http-connections"]=>
  int(0)
  ["load-averages"]=>
  array(3) {
    [1]=>
    float(0.13)
    [5]=>
    float(0.19)
    [15]=>
    float(0.13)
  }
  ["cpu-usage-percentage"]=>
  float(6.2)
}

Byte-named metrics are returned as actual bytes. Disk total is the total size of the root filesystem, not its remaining free space. A metric returns null when its command output is unavailable or cannot be validated; a server with no swap configured reports zero swap usage.

Selecting metrics

To avoid unnecessary SSH commands, pass only the metric classes you need:

use JordJD\ServerInfo\Metrics\Hostname;
use JordJD\ServerInfo\Metrics\LoadAverages;

$metrics = (new Server($connection))
    ->metrics([Hostname::class, LoadAverages::class])
    ->toArray();

Custom metric classes may also be supplied when they implement JordJD\ServerInfo\Interfaces\MetricInterface.

Remote requirements

The target is expected to be a Linux server with /proc, POSIX shell tools, awk, df, and top. Active HTTP connections use ss when available and fall back to netstat. Service checks use pgrep and recognize both MySQL and MariaDB process names.

Compatibility

PHP 7.1 through the current PHP 8.x releases are supported. Versions 3, 4, and 5 of jord-jd/php-ssh-connection are accepted, allowing Composer to select the newest release compatible with the running PHP version. PHP 7.1 installations will continue to receive SSH connection version 3 or 4 because version 5 needs PHP 7.2; this package's PHP minimum has not changed.

Upgrading to 4.0

Earlier releases mislabeled KiB values as bytes and returned available disk space from total-disk-space-bytes. Version 4 returns actual byte values and the root filesystem's total capacity. Consumers that store or threshold these three metrics should update their expected values accordingly.
