README

First you need to install Spatie Server Monitor Package.

Then you need to install this package

composer require jcergolj/extra-checks-for-spatie-laravel-server-monitor

Finally add the following checks to config\server-monitor.php file

'checks' => [
    'diskspace' => Spatie\ServerMonitor\CheckDefinitions\Diskspace::class,
    'elasticsearch' => Spatie\ServerMonitor\CheckDefinitions\Elasticsearch::class,
    'memcached' => Spatie\ServerMonitor\CheckDefinitions\Memcached::class,
    'mysql' => Spatie\ServerMonitor\CheckDefinitions\MySql::class,
    'cpu-load' => Jcergolj\CustomChecks\CpuLoadCheck::class,
    'redis' => Jcergolj\CustomChecks\RedisCheck::class,
    'redis-memory' => Jcergolj\CustomChecks\RedisMemoryCheck::class,
    'horizon-artisan-command' => Jcergolj\CustomChecks\HorizonArtisanCommandCheck::class,
    'horizon-supervisor' => Jcergolj\CustomChecks\HorizonSupervisorCheck::class,
    'horizon-worker' => Jcergolj\CustomChecks\HorizonWorkerCheck::class,
    'queue-worker' => Jcergolj\CustomChecks\QueueWorkerCheck::class,
    'db-connection-count' => Jcergolj\CustomChecks\DbConnectionCountCheck::class,
],

Custom check overview

CpuLoadCheck

You can specify the number of horizon supervisor processes that should run on the server in server-monitor.php config file. Default value is 1.

// config/server-monitor.php
'horizon' => [
    'supervisor_processes' => 2,
]

HorizonWorkerCheck

It checks if horizon worker process is running.

It executes this command on the server: ps aux | grep -E ".*php([0-9]\.[0-9])? .*artisan horizon:work" | grep -v grep.

You can specify the number of min and max horizon worker processes that should run on the server in server-monitor.php config file. The default value is 1 for both min and max.

// config/server-monitor.php
'horizon' => [
    'min_worker_processes' => 2,
    'max_worker_processes' => 2,
]

QueueWorkerCheck

It checks if queue worker process is running.

It executes this command on the server: ps aux | grep -E ".*php([0-9]\.[0-9])? .*artisan queue:work" | grep -v grep.

You can specify the number of queue worker processes that should run on the server in server-monitor.php config file. The default value is 1.

// config/server-monitor.php
'queue' => [
    'worker_processes' => 2,
]

DbConnectionCountCheck

It checks if the number of mysql connections.

It executes this command on the server: netstat -an | grep 3306 | grep ESTABLISHED.

You can specify the db connection threshold in server-monitor.php config file. The default value is 40.

// config/server-monitor.php
'mysql' => [
    'connections' => 50,
]

Extra custom options each host with its own values

How are custom values obtained? First we check if host specific value exists, then the general one in the config lastly if there is none the default value is used.
